Ingersoll/Rand 5 Inch Disc Backup Pad

The Ingersoll/Rand 49877-1 is a foam backup pad designed for adhesive-backed abrasive discs. It fits sanders with a 5/16 In. -24 threaded shaft connector. The round pad measures 5 in diameter and 3/8 in thickness. It suits operators who need a soft density surface for contour sanding tasks.

Sustained Load Performance

Rated for a maximum operating speed of 12, 000 RPM, the pad maintains structural integrity during continuous high-speed sanding. The foam construction absorbs vibration to reduce operator fatigue over long sessions. A non-vacuum design means dust extraction relies on external shop systems. The adhesive mount keeps discs secure under prolonged centrifugal force.

Build Quality and Mounting

The soft density foam conforms to curved workpieces without creating flat spots. A threaded shaft ensures a fixed connection that will not loosen during use. The PSA face allows quick disc changes without tools or a quick-change mechanism. The 5 in diameter matches standard orbital sander orbits for even wear distribution.

Questions about this item

How much heat or noise does the 5 in backup pad generate when running at 12,000 RPM all day?

The foam pad itself produces no heat or noise; any sound or warmth comes from the sander motor and the abrasive contact surface during operation.

What sander shaft does the 5/16 in.-24 threaded connector on this pad require?

It fits any sander with a matching 5/16 in.-24 threaded output shaft; the pad mounts directly without an adapter.

Will the 5 in diameter and 3/8 in thickness work with my older orbital sander that uses hook-and-loop discs?

No, this pad uses a PSA adhesive-backed mounting system, so it is not compatible with hook-and-loop disc sanders.
