4 Pack 25Mm Universal Roller Ball Casters for Easy Sliding
✔️ 4 packs supply smooth 25mm tracks with 8mm stems 22mm long

This set of four heavy duty roller ball transfer bearings creates a low friction sliding layer for shop tables, loading docks, and small conveyors. Workers push materials across the rolling spheres instead of dragging heavy boxes, which saves time and protects delicate finishes.

✅ Rollers measure 25mm or 1 inch wide for consistent forward motion ✅ Mounting stems fit 8mm or 0.32 inch clearance holes perfectly ✅ Stem thickness reaches 22mm or 0.87 inch into base plates securely ✅ Each unit supports up to 55 pounds of steady distributed weight ✅ Getting started takes minutes since screws thread right into wood

💡 What makes roller ball transfer bearings handy for light manufacturing lines? These casters remove drag by rolling weight across sealed spherical tracks that glide under any rigid platform. - Free spinning internal rings prevent surface scuffing on epoxy floors - Tight threaded stems lock firmly into pre drilled plywood or aluminum frames - Even weight spacing reduces muscle strain during repetitive cart moves - Modular layout lets you arrange caster patterns for maximum ground coverage
