Heavy Duty Oilless Bronze Bearing For Industrial Gear
✔️ 50mm bore, 55mm OD, 30mm length, single unit, sintered bronze carbon steel

This single pack oilless sleeve bearing serves as a reliable lubrication-free pivot point for sliding shafts across workshop tools and factory conveyor drives.

✅ Inside diameter measures 50mm or 1.97 inches for standard shaft fits
✅ Outside diameter spans 55mm or 2.17 inches to house securely in metal sleeves
✅ Overall thickness hits 30mm or 1.18 inches to save valuable cabinet space
✅ Sintered copper alloy shell over hardened steel core handles heavy loads
✅ Dry running design cuts down maintenance trips while keeping friction low

💡 Why pick dry slide bushes over traditional oil feed journals for linear motion tracks?
The copper sintered shell plays handy under relentless shop floor abuse since its built-in lubricant layer keeps things rolling slick.
- fused metallic pores spit out a steady film of grease exactly when friction ramps up
- heavy steel backing keeps the housing rock solid against lateral shoves and sudden startup jolts
- massive sweat savings show up quick when you skip weekly greasing runs and cleanout schedules
