THK Rail Plugs: For THK SR35/HSR30/HSR35 Rails

THK rail plugs are plastic covers that seal the mounting holes on THK SR35, HSR30, and HSR35 profile rails. They prevent debris, coolant, and chips from entering the rail mounting holes, protecting the rail surface and extending the life of the linear guide system in industrial automation and machine tool applications.

The THK rail plug model C8 is a plastic plug designed for THK SR35, HSR30, and HSR35 profile rails. It is compatible with manufacturer model numbers SR35, HSR30, HSR35, and HR. The part number is C8, and the plugs are made by THK. They fit the rail mounting holes to keep them clean and free of contaminants.

To install THK rail plugs, first clean the mounting holes on the SR35 rail to remove any dirt or oil. Then press the C8 plastic plug firmly into the hole until it sits flush with the rail surface. No tools are required. Ensure the plug is fully seated to prevent debris ingress. Repeat for each mounting hole along the rail.
