Pneumatic Drum for Belt Finishing

This pneumatic drum fits the LINE-MATE system and uses a 5/8-11 threaded arbor for secure mounting. The air cushion between drum and belt prevents edge cutting and swirl marks during surface preparation. Designed for workshops that finish metal with coated abrasive belts, it helps extend belt life by lowering heat buildup. Operators seeking consistent results on contoured parts will find the wide contact area useful.

Threaded Arbor and Air-Cushion Build

The internal 5/8-11 thread locks directly onto compatible drive spindles without extra adapters. Compressed air inflates the drum, creating a flexible backing that conforms to workpiece shapes while reducing vibration. This construction limits aggressive contact that can gouge material, making day-to-day finishing smoother and more predictable. The drum ships new and ready for immediate installation on supported equipment.

Extended Belt Life and Surface Quality

By distributing pressure evenly across the belt, the air cushion cuts heat accumulation that normally degrades abrasive cloth. Belts therefore stay sharp longer, lowering consumable cost over time. The design also minimises swirl patterns, reducing the need for secondary polishing steps. Buyers who need rigid, non-compliant contact wheels or who work without a compressed-air supply should consider alternative tooling.
