Quality Requirements For WSBC Bearing Appearance

Time：2020.04.23  Source：Roller Bearings Suppliers

Wuxi Spark Bearing Co.,Ltd quality department has our own criterion for bearing appearance,All of our bearings are following as below:

1. Bearing parts are not allowed to have cracks, sharp edges, burrs and rust;The raceway is not allowed to have the trace of the process;The superfine lines of the inner and outer ring and steel ball face should be uniform, and no abrasions and bruises are allowed.

2. the bearing parts with surface grinding grain should be rules are the same, there is no swirl marks, marks, Yin and Yang face and grinding marks, are not allowed to appear and obvious trace measuring bearing seal, are not allowed to have knocked wounded and obvious color difference.

3. No oxide coating is allowed on the part surface.Ring chamfering, inner diameter and inner diameter are required to be brightened.

4. When the bearing ring parts are pickling, the working surface should not be burned, and the surface should not be damaged without acid cleaning, and the hardness test should not be affected.

5. Assembly chamfering. 

A. Assembly chamfering size and chamfering shape shall conform to the requirements of our product drawings. 

B. The chamfer surface is not corroded and bruised.

6. Steel ball

Steel ball appearance quality standards shall comply with JB/T10861 standard requirements.

7. Cage

The surface should be flat, smooth, without burr, bruise, no rust and obvious color difference. It is not allowed to have the appearance defects such as compression, contusion, deformation and sand eye.

For Example:Full cylindrical roller bearing RSL18 is designed to withstand heavy loads.In the same width, this bearing and the traditional belt cage bearing, has a very high bearing capacity, radial section is small, can save space, but the speed is relatively low.All multi-row cylindrical roller bearings have a lubrication groove and a lubrication hole in the outer ring.

In order for the bearing to work properly, in the case of continuous operation, the bearing must bear a certain minimum load, that is, C/P<25.Otherwise due to insufficient lubrication and high speed operation will aggravate wear.

Full load bearings shall be of GB/ t307.1-94 (iso492-1994)P0 grade with normal radial clearance (CO) and may require original radial clearance from (C2) to (C4).However, the corresponding clearance suffix letter should be added after the bearing code when ordering.Rubber - plastic screw extruder generally USES C3 group clearance.

Fit tolerance can refer to the bearing housing and shaft tolerance limit selection principle.

Bearings are allowed to bear certain axial loads.Adequate lubrication is a prerequisite for bearing axial loads.Unidirectional positioning bearings and positioning bearings whose retaining edges are subjected to axial loads must be fully supported.During installation and disassembly, the installation or disassembly force cannot be directly transmitted through the cylinder roller and the rim of the ring.Need 24134CC/W33,click here.
