Simple Oil Free Bronze Sleeve Bearing Unit
✔️ Bore 3mm OD 5mm Length 5mm Bronze core self lubed 0305 pack of 1

This handy single piece oilless bushing pairs a carbon steel base with a sintered porous bronze shell to deliver steady rotation without messy grease jobs. Available in a 3mm bore (0.12 inch) and 5mm outside diameter plus 5mm length (0.20 x 0.20 inch), you will drop these compact rings right into fitness machine pivots, hydraulic arm linkages, and workshop motor mounts where clean operation and steady load handling matter most.

✅ Carbon steel substrate bonded to porous bronze overlay for tough spindle support
✅ Zero drip dry friction setup keeps gritty shop air out while lowering resistance
✅ Abrasion resistant lining guards drive shafts against chatter during heavy vibration cycles
✅ Three five five mm (0.12 x 0.20 x 0.20 inch) cross section drops neatly into custom gearboxes

💡 Why do technicians specify plain cylindrical bushes over sealed rolling elements for slow pivot joints?
This handy replacement ring removes the drip station hassle while keeping your hardware aligned under pressure.
- Sintered bronze matrices feed consistent dry film to reduce spindle wear rates
- Carbon steel substrates absorb shock loads that would crush softer polymer sleeves
- Tolerant inner bores clamp tightly onto mild steel axles without spinning loose
