Angular contact ball bearing for ball screws
This bearing used to support the ball screw. The ball screw belongs to robot transmission mechanism, which requires high precision, high speed machine tool and confidential measuring equipment. This is a kind of high precision, high performance bearing.
Design features:
1、High rigidity: This bearing use nylon cage, and the quantity of steel ball is more than that of ordinary angular contact bearing.
2、Easy to install and adjustment: This bearing has pre-set pre-load, so it is easily installed, without installation torque measurement.
3、Simplified bearing installation structure: This bearing has 60 ° contact angle, and it can bear radial and axial load together. It also simplifies the structure of shaft and shaft washer.
Precision matched stack bearing has （G）A、（G）B、（G）C mark on suffix, A stands for light pre-load, and B stands for middle pre-load, while C stands for heavy pre-load. G is for universal group matches, this product can allow two or more arbitrary matched stack used bearing.
WZFB can provide high precision ball screw thrust bearing with P4, P2 class.
