Closing plugs

The closing plugs close off the counterbores for the fixing screws in the guideway holes flush with the surface of the guideway.

The closing plugs are available in a one-piece or two-piece design and are made from various materials. In addition to the plastic closing plugs, closing plugs made from brass and steel are also available.

ACHTUNG

If closing plugs are used in coated guideways, only plastic closing plugs or two-piece brass or steel closing plugs with a clinch ring can be used.

ACHTUNG

When fitting the closing plugs, observe the guidelines in the Technical principles.

Plastic closing plugs

Plastic closing plugs are an economical solution and are suitable for most applications, ➤ Figure.

Plastic closing plugs, one-piece

The one-piece closing plugs KA..-TN can be easily fitted with the aid of a hammer and press-in block. The interference between the plug and hole creates a burr that must be removed during fitting. After fitting, a minimal ring gap remains.

Plastic closing plugs with clinch ring

The two-piece closing plugs KA..-TN/A comprise a plastic plug and a plastic clinch ring. The clinch ring ensures secure seating of the closing plug in the counterbore. These closing plugs can also be easily fitted with the aid of a hammer and press-in block. After fitting, a small ring gap remains.
