15Mm Inner Diameter X 17Mm Outer Diameter X 20Mm Long Oilless Sleeve Bearing Carbon Steel Bronze Bushing Solid Plain Bearing Built Tough For Industrial Machines And Electrical Systems Straight Up Smooth Running Heavy Duty
✔️ 15mm bore 17mm outside measure 20mm total span bronze build
This single piece oilless sleeve bearing delivers smooth rotation and reliable durability for everyday machine operations. Made with a solid carbon steel exterior and a sintered copper core, it handles moderate loads while keeping friction low. You will commonly find these straight slide units installed inside textile mills, printing presses, hydraulic loaders, fitness gear, and farm tractors. They take the shock out of moving parts and protect shafts from wear without requiring constant grease.
✅ 15mm inner diameter 0.59 inch matches standard shaft sizes✅ 17mm outside diameter 0.67 inch provides sturdy mounting clearance
✅ 20mm overall length 0.79 inch fits tight housing spaces
✅ Sintered bronze inner layer reduces dry friction to 0.04 value
✅ Maintenance free build keeps gears and motors running clean
💡 How does a dry sliding sleeve improve long term reliability on heavy factory loads?
A handy plain bearing removes messy grease jobs and stops rust from freezing your drive shafts.
1. The porous bronze matrix traps just enough lubricant to handle moderate speeds without dripping onto belts or gears.
2. Metal surfaces glide smoothly under pressure while bypassing the frequent teardown cycles that kill uptime.
3. You maintain consistent torque transfer and extend motor lifespan across tough industrial environments.
