Single Row Angular Contact Bearings

ktai — Wed, 09 Nov 2016 09:11:10 +0000

Single Row Angular Contact Bearings can withstand axial load in one direction, the radial load, it will cause additional axial force must be applied to the corresponding reverse load. Therefore, the types of bearings are generally used in pairs.

bearing material: chrome steel GCr15/52100/100Cr6
bearing tolerance: P0(ABEC-1), P6(ABEC-3), P5(ABEC-5), P4(ABEC-7)
contact angle: C-15^。, AC-25^。, B-40^。, A-30^。,
different angles are available on request.
Type code:
7-the counter bored outer ring
S7-the outer ring is separable
SN7-the inner ring is separable
B7-the stepped inner ring

Bakelite cage

Nylon cage

Brass cage: Y-pressed brass sheet; M: machined brass solid

Steel cage: J-pressed steel sheet

High Speed Angular Contact Bearings

ktai — Tue, 08 Nov 2016 16:35:41 +0000

High Speed Angular Contact Bearings can bear radial load and one direction axial load. When the bearing withstands radial loads, axial force will be generated on inner ring.

Therefore, the single-row angular contact ball bearings are often used with other bearings which can withstand axial load in the opposite direction.

They are used in machine tools spindle, high speed motor, robots and so on.

Double Row Angular Contact Bearings

ktai — Mon, 07 Nov 2016 18:49:03 +0000

Double Row Angular Contact Bearings correspond in design to two single row angular contact ball bearings arranged back-to-back.

They can take a bi-directional axial load in one bearing where it takes a matched pair otherwise, which means the bearings can accommodate radial loads as well as axial loads in both directions.

Matched Pair Angular Contact Bearings

ktai — Sat, 05 Nov 2016 10:45:15 +0000

Matched Pair Angular Contact Bearings, also called duplex bearings, are machined as matched sets. The pairs are furnished with the race faces ground to provide preload when installed. To accomplish this, a gap is provided between the inner races or outer race of the pair.

There are three types duplex bearing arrangements commonly used and they are Back to Back, Face to Face and Tandem bearing arrangement.

DB: back to back bearing arrangement—gap is provided between inner races
It is a type of duplex bearing arrangement where the two half are placed so that contact angle lines of the bearing diverge inwardly. And these contact angle lines form ‘O’ shape, hence called as “O arrangement”.
In back to back arrangement a gap is provided between inner races and when installed, this gap is closed and producing a preload on the bearings. DB arrangement has higher moment stiffness.
They can carry heavy radial loads, combined radial and thrust loads, reversing thrust load, moment loads.

DF: face to face bearing arrangement—gap is provided between outer races
It is a type of duplex bearing arrangement where the two half are placed so that contact angle lines of the bearing converge inwardly. And these contact angle lines form ‘X’ shape, hence called as “X arrangement”.
In face to face arrangement a gap is provided between outer races and when installed, this gap is closed and producing a preload on the bearings. DF arrangement has lower moment stiffness, so they must be spaced sufficiently to provide resistance to moment load.
They can carry heavy radial loads, combined radial and thrust loads, reversing thrust load.

DT: Tandem bearing arrangement—only accepts one directional thrust load
It is a type of duplex bearing arrangement where the two half are placed so that contact angle lines are parallel. This arrangement makes a very heavy duty thrust bearing arrangement, but it will not carry any radial load and accepts thrust loading in only one direction.

Three/Four Points Angular Contact Bearings

ktai — Fri, 04 Nov 2016 11:12:36 +0000

Three/Four Points Angular Contact Bearings are a type of single row angular contact ball bearing, they can support radial load and axial load in both directions.

The inner ring is split, and the bearings are separable, i.e. the inner ring halves and the outer ring with ball and cage assembly can be mounted individually.

bearing material: chrome steel GCr15/52100/100Cr6
cage: brass
bearing tolerance: P0(ABEC-1), P6(ABEC-3), P5(ABEC-5)
clearance: C0(standard)
contact angle: 35^。
QJS: three points angular contact bearings
QJ: four points angular contact bearings
four points angular contact bearing with more than 160mm outer ring diameter can be two locating slot in the outer ring(suffix N2).
