Recirculating linear bearings
Our recirculating linear bearing is a core component for high-stability linear motion systems, featuring high rigidity, low friction, and precise positioning.
Features
High position precision
Durable table operation, slipping occurs, and it can achieve Micron-level positioning accuracy.
Low wear, maintains precision for long periods
The wear of the rolling guide is very small, so it can maintain precision for a long time.
Suitable for high speed motion & reduces drive power significantly
The linear guide has very low friction during movement, generating, less heat, making it suitable for high speed operation.
Can bear loads in up, down, left, and right directions simultaneously
The linear guide`s special constraint structure design allows it to bear loads in up, down, left and right directions at the same time.
Easy assembly & interchangeability
During assembly, just mill to grind the mounting surface of the guide on the machine table, and fix the guide and slider to the machine with specific torque according to the recommended steps to restore high precision during processing.
Simple lubrication structure
The linear guide is equipped with oil nozzle on the slider; grease can be injected directly with an oil gun, or a special oil pipe joint can be installed to connect the oil supply pipe for lubrication with an automatic oil feeder.

Installation method of slide rail |
|
|
1.clean the dirt on the assembly surface of the machine table. |
2.place the slide rail smoothly on the machine table , and fit with the reference surface of machine table. |
|
|
|
|
3.temporarily tighten the assembly screws to check if the screw holes align, and roughly fix the reference surface at the bottom of the slide rail to assembly surface at the bottom of the machine table. |
4.use lateral fixing screw to sequentially push the side reference surface to the slide rail against the side assembly surface of the machine table to confirm the slide rail`s position. |
|
|
|
|
5.use a torque wrench to tighten each screw in sequence with a specific torque, pushing the reference at the bottom of the slide rail tightly against the assembly surface at the bottom of the machine. |
6.install the remain matching slide rails according steps 1 to 5. |
