Ball Screw Bearing

Ball screw bearing also called ball screw support unit. The bearing for ball screws is used as fixed end support bearings for ball screw. They are designed to take the axial and radial load. These end support ball bearings are designed so that the bearing stiffness is greater than conventional bearings, which allows the machine structure to hold accurate position under heavy load.


1.  The ball screw bearings  Product Introduction

The ball screw bearings are divided into two types as following:

The BK,EK,FK fixed-side support unit contains two angular contact bearings that provide both axial and rotational support for the ball screw.

2. The BF,EF,FF supported-side support unit has only a standard ball bearing that provides rotational support on the end of the ball screw opposite of where the drive occurs (typically a motor or pulley).

3. Our standard ball screws are supplied with machining that will work with these supports without modification.

BK type          

thrust pillow block fixed 


BF type

radial simple support


EK type

fixed side


EF type

floated side


FK type

flange mount thrust bearing


FF type

flange mount simple support



1.High-speed operation
2.Low friction and noise
3.High precision, duration, and reliability
4.Smooth movement      
5.High efficiency of transferring


Ball screw bearing that achieves low noise, small torque fluctuations and long-term maintenance-free .

Therefore it’s widely used in automatic controlling machine,general industry machinery,printing, paper-processing, automatic machines, textiles, robot, measuring instruments, medical equipment, X-Y table,CNC route grinding machine, cutting bending machine ,medical equipment etc.

4.Deliver,Shipping And Serving

Ball screw package is plastic bag+box case or wooden case.
