The CGW 36204 is a 4-1/2 inch diameter, 7/8 inch arbor polymer resin fibre disc back-up pad designed to be used with fibre discs for surface grinding and blending applications. This back-up pad serves as a stable mounting surface that helps maintain consistent contact and disc shape during operation, contributing to even dress and extended disc life when paired with appropriate abrasive discs.
Construction highlights include a flexible rubber pad option for contoured work and a rigid pad option for more aggressive grinding tasks. The design incorporates spiral ribs that create contact points and channels for improved air flow, which supports cooler operation and can extend disc life by an estimated 30% to 50% by reducing heat buildup. Larger air holes further aid cooling and heat management during lengthy grinding cycles. These features collectively help maintain abrasive efficiency and finish quality while reducing premature wear on the pad and disc.
This pad is sized for a 4-1/2 inch disc with a 5/8-11 arbor/shank and is rated for up to 11,000 RPM, making it suitable for standard high-speed surface finishing operations on appropriate materials. It is sold as a single unit and is intended for facility maintenance use, where reliable backing support is needed to achieve consistent results with medium-grit abrasive discs. When selecting a pad, consider the contour needs of the workpiece and the aggressiveness of the grinding task to choose between flexible and rigid pad variants, and ensure compatibility with your disc type.
