Primary grouping
Bearing characterization
Sliding Bearings
Sliding orientation are not isolated into inward and external rings and don’t have a moving body, however are for the most part made of wear-safe materials. They are ordinarily utilized at low velocities, light loads and in hardware where grease and support are troublesome.
Joint orientation
Joint direction have a round sliding contact surface and are principally utilized for swaying, shifting and turning developments.
Moving course
Moving course are partitioned into outspread orientation and push heading as per the bearing of the heap they can convey or the ostensible contact point. Among them, outspread contact orientation for the ostensible contact point of 0 centripetal headings, centripetal precise contact course for the ostensible contact point of more than 0 to 45 centripetal headings. Pivotal contact heading for the ostensible contact point of 90 push orientation, push rakish contact course for the ostensible contact point more prominent than 45 yet under 90 push direction.
As indicated by the state of the moving body can be separated into metal balls and roller heading. Roller course are isolated into tube shaped roller heading, needle orientation, tightened roller direction and circular roller orientation as per the sort of roller.
As indicated by its work can be separated into round course – – – – raceway is circular, can adjust to the two raceway pivot line between the rakish deviation and precise development of the bearing and non-round direction (unbending bearing) – – – – can hinder the raceway between the hub line rakish offset orientation.
As indicated by the quantity of sections of moving body is separated into single line bearing, twofold line bearing and multi-column bearing.
As per its parts (collar) can be isolated into distinct direction and non-distinguishable heading.
As indicated by its construction shape, (for example, regardless of filling groove, regardless of inward and external ring and the state of the collar, the design of the holding edge, even regardless of keep outline, and so forth) can likewise be separated into an assortment of underlying sorts.
As indicated by its external width size is isolated into scaled down direction (<26mm), little heading (28-55mm), little and medium-sized course (60-115), medium and enormous orientation (120-190mm), huge orientation (200-430mm) and exceptionally huge direction (>440mm).
As per the application region, it is separated into engine course, moving factory orientation, principle direction, and so on
As per the material is isolated into clay direction, plastic heading, and so forth
Profound furrow metal balls
Profound furrow metal balls are the most delegate moving direction. Contrasted and different kinds of orientation of a similar size, this sort of bearing has a little coefficient of rubbing, high cutoff speed, basic construction, low assembling cost, high accuracy, no requirement for incessant support, and an enormous scope of sizes and structures, is the most broadly utilized sort of bearing. It primarily bears spiral burden, yet additionally can bear a specific pivotal burden. Whenever it just bear spiral burden, the contact point is zero.
Profound score metal roller introduced in the shaft, in the course of the pivotal freedom range, can restrict the shaft or shell two bearings of hub uprooting, so can be in two headings for hub situating. Whenever the profound furrow metal roller has an enormous outspread freedom, with rakish contact bearing execution, can endure the bigger pivotal burden . In the pivotal burden is exceptionally huge under rapid working circumstances, profound notch metal rollers than push metal balls have greater predominance. Furthermore, this kind of bearing likewise has a certain changing capacity, when comparative with the shell opening slant 2′ ~ 10′ when, actually can work ordinarily, however the bearing life has a specific impact.
Precise contact metal ball
By and large standard known as 36, 46 sort bearing as a delegate of the six kinds of direction, rakish contact is for the most part 15 degrees, 25 degrees, 45 degrees, and so forth
Circular metal balls
Circular metal balls
Circular metal balls
Circular metal balls are two raceways of the inward ring and the raceway for the circular surface of the external ring between, collected with a round metal rollers. The focal point of shape of the external raceway surface is equivalent to the focal point of the bearing, so it has a similar arrangement work as oneself adjusting metal roller. In case of diversion of the shaft or lodging, it tends to be consequently changed without expanding the weight on the bearing. Circular roller orientation can bear spiral burden and two headings of hub load. Circular metal ball outspread burden limit is huge, reasonable for there is weighty burden, shock load circumstance. Internal ring inward distance across is tightened opening bearing, can be straightforwardly mounted. Or on the other hand utilize the fixing sleeve, dismantling chamber mounted on the tube shaped shaft. The enclosure is made of squeezed steel plate, polyamide framing. Round metal balls are appropriate for bearing weighty loads and shock loads, accuracy instruments, low-commotion engines, vehicles, motorbikes, metallurgy, moving factories, mines, oil, paper, concrete, sugar and different enterprises and general hardware, and so on
Push metal balls
Push metal balls are partitioned into one-way and two-way. They can bear pivotal burden, can never bear any outspread burden. Push bearing is isolated into tight circle and live circle two sections. Tight circle and shaft sleeve tight, live circle support in the bearing seat. The ring and moving body generally utilize high strength, great wear opposition of moving bearing steel producing, extinguishing the surface hardness should arrive at HRC60 ~ 65. keep outline more with delicate steel stepping made, can likewise be utilized copper combination sandwich material elastic wood or plastic and other assembling.
Twofold directional push precise contact metal balls
Twofold column tightened roller course
Twofold column tightened roller orientation
Push rakish contact metal ball contact point is for the most part 60 ° regularly utilized push rakish contact metal ball is by and large two-way pushed rakish contact metal ball, basically utilized for accuracy machine device shaft, for the most part with twofold column round and hollow roller course together, can bear two-way pivotal burden, with high accuracy, china Bearing manufacturers great unbending nature, low temperature rise, fast, simple to introduce and dismantle and different benefits.
Push roller orientation
Counting push round and hollow roller direction, push tightened roller orientation, push needle roller heading and push circular roller course.
Needle roller heading
Needle roller direction are outfitted with slight and long rollers (roller length for the measurement of 3 to multiple times, the width is by and large not more than 5mm), so the spiral design is conservative, its internal breadth size and burden limit with different sorts of course, the external distance across of the littlest, particularly reasonable for outspread establishment size is restricted help structure. Needle roller heading as indicated by the utilization of various events, can pick no internal ring course or needle roller and enclosure get together, this time with the holding on for the diary surface and shell opening surface straightforwardly as the orientation of the inward and external moving surface, to guarantee the heap limit and running execution with the sleeve bearing something similar, shaft or shell opening raceway surface hardness, machining precision and surface quality ought to accompany the bearing sleeve. Consolidated needle roller bearing is a blend of needle roller bearing and push bearing parts bearing unit, its smaller design and little volume, high rotational exactness, can bear a high spiral burden simultaneously bear a specific hub load. Furthermore the item structure different, flexibility, simple to introduce. Joined needle roller course are generally utilized in machine instruments, metallurgical apparatus, material hardware and printing hardware and other mechanical gear, and can make the mechanical framework configuration is exceptionally minimal and handy.
Outside circular metal balls
Outside circular metal balls have a round surface on the external breadth of the external ring, which can assume a circular part.
Round Roller Bearings
Round roller heading have two columns of balanced circular roller, predominantly bear outspread burden, yet in addition can endure either course of the hub load, yet can not bear unadulterated hub load. This kind of bearing external ring raceway is round, so its arrangement execution is great, can make up for coaxiality blunder, when the shaft is bowed or introduced different heart bearing can in any case ordinary use, arrangement with bearing size series and unique, the overall permitted arrangement plot for 1 ~ 2.5 degrees, the sort of bearing burden limit, notwithstanding bear spiral burden bearing can likewise endure two-way job of the hub load, has a decent Impact opposition, by and large, circular roller course permitted to work at a lower speed. Reasonable for weighty burden or vibration load work.
Spine orientation
Spine orientation have a rib on the external wheel. They are portrayed by an improved on centralized computer development, diminished centralized computer aspects and more straightforward bearing situating.
Heading with lodging
A mix of an outspread bearing and a seat in a part with a help surface corresponding to the pivot of the holding on for a base plate for mounting screws.
Consolidated course
A bunch of direction in a blend of the over at least two bearing construction structure moving bearing. For example, needle roller and push barrel shaped roller blend direction, needle roller and push ball mix course, needle roller and precise contact ball mix orientation, and so on
Straight heading
Direct heading are isolated into metal straight course and plastic direct orientation.
Metal direct heading are a straight movement framework delivered for minimal price for use with tube shaped shafts with limitless travel. Since the transporter balls are in point contact with the shaft, the heaps utilized are little.
