CGW 48224 is a medium-smooth resin fiber disc back-up pad designed for use with 4-1/2 inch diameter sanding discs that mount on 5/8-11 threaded arbors. This back-up pad supports grinding operations by providing a flexible rubber surface for contouring and a rigid option for more aggressive applications, helping to optimize disc performance across a range of materials. The design emphasizes heat management and disc life through air-flow channels and larger air holes, features that reduce heat buildup and extend abrasive life during extended use.
The pad utilizes spiral ribs to create contact points and form air channels, which improves airflow under the disc. This construction contributes to cooler operation and up to an estimated 30% to 50% longer disc life by mitigating heat-related wear. When paired with coarse grits, the rubber back-up pad can adapt to curved surfaces, while the rigid variant remains effective on tougher, more demanding grinding tasks.
For buyers, this back-up pad is sized to fit 4-1/2 inch discs with an arbor/shank size of 5/8-11 and is rated for up to 11,000 RPM, making it suitable for a variety of surface finishing jobs in facility maintenance. Each package contains one pad, ready to install on compatible grinders.
