Rock Solid Oilless Plain Sleeve Bearing 5mm Id X 7mm Od X 5mm Length Carbon Steel Bronze Bushing Keeps Your Electrical Motors Rolling Smooth And Zero Sweat

Precision oilless plain bearing bushing for electric motors
✔️ 5mm (0.20in) bore x 7mm OD x 5mm length bronze sleeve

This one piece oilless plain sleeve bearing combines a carbon steel shell with a sintered bronze core to deliver steady rotary motion without messy greases. Equipment builders and garage tinkerers slide these zero drip rings into treadmill axles, printing rollers, and light industrial drives to absorb shock and hold shaft positions under moderate loads. You get exactly one rugged bushing per pack.

✅ 5mm (0.20in) inner hole accepts standard metric drive pins and nylon rods
✅ 7mm (0.28in) outer diameter seats tightly in cast aluminum or steel housings
✅ 5mm (0.20in) overall width matches standard slot depths for quick swaps
✅ Porous copper matrix maintains a dry friction coefficient from 0.04 to 0.2

💡 What keeps industrial shaft alignment steady while skipping routine grease up?

The dry running bushing handles tough workshop grime so mechanics skip daily maintenance routines.
- The porous metal core transfers copper traces onto the journal surface to lower kinetic drag during hot run periods
- Technicians grab these cheap replacements to fix stiff hinges on agricultural harvesters without taking whole units apart
- A handy dry film lubricant setup prevents rust flash when equipment sits idle past rainy season storage
