Straight Up Heavy Duty Single Sleeve Bearing Measuring 50Mm X 55Mm X 30Mm Oilless Bushing Made From Durable Carbon Steel And Bronze For Smooth Machinery Operation Without Extra Fuss

Heavy Duty Single Sleeve Bearing With Bronze Core
✔️ Bore 50 mm 1.97 inch OD 55 mm 2.17 inch L 30 mm 1.18 inch

This single pack of maintenance free oilless bushings swaps out noisy grease fittings in heavy equipment. The self lubricating bronze coating works smoothly on fitness racks, printing presses, and hydraulic loaders where steady speed and moderate weight are common.

✅ Carbon steel backing fused with sintered copper layer takes heavy radial loads
✅ Porous bronze matrix holds dry lubricant for constant slip performance
✅ Low friction surface reduces shaft damage during startup cycling
✅ Exact dimensional tolerance allows quick drop replacement in tight frames

💡 What makes a plain sleeve bushing handy for keeping industrial drives running smooth? This self lubricating component stays reliable when shops skip daily greasing routines. Mechanics swear by this design for four solid reasons:
- Sintered bronze inner layer delivers steady slip resistance without oil pumps
- Direct carbon steel outer wall grips housing bores tightly against vibration
- Precise millimeter sizing slides into legacy equipment frames without modification
- Dry running friction cuts maintenance downtime and extends motor life
