Expansion Rubber Roller – 75 x 25 x 30mm

Designed for use with compatible abrasive bands and sleeves, this expansion rubber roller provides secure support for sanding, grinding, finishing, and polishing applications. As the roller rotates, centrifugal force causes the rubber body to expand, helping hold the abrasive band firmly in place during operation.

The flexible rubber construction provides support across the abrasive surface while allowing efficient contact with the workpiece. It is a useful choice for jewelry fabrication, metalworking, surface preparation, deburring, and finishing applications where controlled material removal and a consistent finish are important.

With a 75mm diameter, 25mm working width, and 30mm bore, this roller is designed for compatible polishing and finishing equipment.
