Description

Cowhide Polyurethane Rubber Band for Clamp Panel and Cylinder – 60mm Yellow Grip Block

The Cowhide Polyurethane Rubber Band for Clamp Panel and Cylinder Framing Machine is the grip interface between your machine’s metal clamp jaw and the picture frame moulding. Despite its traditional name referencing original cowhide leather versions, this modern component is manufactured from high-durometer yellow polyurethane for superior performance and longevity.

Specifications

Length: 60mm. Width: 25mm. Height/Thickness: 12mm. Color: Yellow. Material: High-durometer polyurethane. Slightly rounded top edges prevent point-load stress concentrations on delicate moulding surfaces.

Function in the Clamping System

During the clamping phase of the nailing cycle, the Cowhide Polyurethane Rubber Band for Clamp Panel and Cylinder Framing Machine compresses slightly between the metal jaw and the moulding surface, distributing clamping force over a larger area. This prevents jaw indentation marks on soft or finish-coated mouldings while maintaining sufficient grip.

Material Choice – Why Yellow Polyurethane?

Yellow polyurethane has a higher Shore hardness than the red polyurethane used in pressing blocks. This makes the cowhide rubber band more resistant to permanent compression set when used in continuous clamping applications.

Replacement

Replace when the block shows visible surface glazing, cracking, or any permanent compression deformation that prevents it from seating flat in the clamp jaw.

Complete your clamping system with a new Pressing Block and Press Head Rubber Band.

FAQ

Why is this called a 'cowhide' rubber band?

The Chinese name (cowhide elastic) reflects the traditional material this component was once made from — genuine cowhide leather. Modern versions are made from high-durometer yellow polyurethane, which is more durable and consistent.

What are the dimensions?

The block measures 60mm in length, 25mm in width, and 12mm in height (thickness). It is a flat rectangular block with slightly rounded edges on the top face.

Which machines use this rubber band?

This cowhide rubber band is used with the clamp panel (??) and clamping cylinder (????) assemblies found in corner nailing machines and frame assembly aids.
