Dynabrade 56185 Disc Backing Pad Psa 13000 Rpm

Product Description

The DYNABRADE 56185 is a PSA (pressure-sensitive adhesive) disc backing pad designed for use with random orbital sanders. It features a 5/16-24 male threaded mount for secure, vibration-resistant attachment to compatible sander spindles. Rated to a maximum of 13,000 RPM, this backing pad is built to handle the rotational demands of production sanding applications. The soft-density construction allows the pad to conform to slightly contoured or irregular surfaces, improving abrasive contact and finish consistency. This part is commonly installed by body shop technicians, industrial maintenance professionals, and skilled tradespeople who work with disc-style abrasives on a regular basis.

This backing pad is suited for surface preparation, paint removal, and finishing work where PSA-backed abrasive discs are the preferred consumable. The threaded spindle mount makes tool changes straightforward without requiring additional hardware. Its soft density makes it appropriate for applications where full surface contact on non-flat workpieces is required, such as featheredging, scuffing, or light material removal on automotive panels, metal fabrication parts, or wood substrates.

Key Features

• PSA adhesive interface accepts pressure-sensitive adhesive abrasive discs directly
• 5/16-24 male threaded mount for spindle attachment on compatible random orbital sanders
• 13,000 RPM maximum rating for high-speed sanding applications
• Soft density construction promotes surface conformity on contoured workpieces
• Threaded mount type eliminates need for additional fasteners during pad changes

Compatibility

Designed for use with random orbital sanders that accept a 5/16-24 threaded spindle mount and PSA-backed abrasive discs.

Installation Notes

Installation should be performed by a qualified technician familiar with rotational abrasive tooling. Power off and disconnect the sander from its air supply or power source before threading on or removing the backing pad. Hand-tighten onto the spindle and verify the pad is seated securely before operating at speed. Do not exceed the 13,000 RPM maximum rating of this pad.
