Product Description

The THK Rail Plugs, part number C4, are plastic plugs designed for THK profile rails. They are compatible with THK rail sizes HSR15, HRW17, HRW21, HRW27, and GS models. These plugs serve to cover rail mounting holes, maintaining a clean rail surface.

Frequently Asked Questions

What are THK rail plugs used for?

THK rail plugs, part number C4, are plastic plugs designed to cover mounting holes on THK profile rails. They maintain a clean rail surface and prevent debris from entering the mounting holes, which is critical for linear motion systems in automation, machine tools, and industrial equipment.

What are the specifications of THK rail plugs C4?

The THK C4 rail plugs are plastic plugs compatible with THK rail sizes HSR15, HRW17, HRW21, HRW27, and GS models. They are manufactured by THK under part number C4 and fit rails with model numbers HSR15, HRW17, 2127, and GS. These plugs are used to cover rail mounting holes.

Where to buy THK rail plugs C4 worldwide?
