10 Piece Pro Grade Sleeve Bearing Set 15mm Bore 17mm Outer Diameter 20mm Long Oilless Bushing Bronze Sintered Coating Wear Resistant Low Noise Rock Solid Performance For Machinery

Ten Unit Bronze Bushings For Quiet Axis Rotation Tasks
✔️ 15mm bore 17mm od 20mm length carbon steel bronze sintered sleeve

This set of ten precision sleeve bearings features a thin cylindrical form that cuts down sliding resistance while handling steady axial and radial loads. Mechanics typically install them onto drive shafts for electric fans, conveyor rollers, garden tractors, and compact robotics frames where zero maintenance rotation matters.

✅ Inside measurement 15 mm / 0.59 inch with outside diameter 17 mm / 0.67 inch
✅ Total thickness runs 20 mm / 0.79 inch to save mounting space
✅ Carbon steel inner core covered with sintered bronze composite layer
✅ Dry friction coefficient sits between 0.04 and 0.2 for smooth sliding

💡 What factors make oilless bushings a handy upgrade for residential workshop tools
These self contained rings grab attention from DIYers because they run completely dry without messy grease traps.
- Porous bronze matrix locks in solid lubricant directly into the metal shell
- Low static friction ratings let old lathe spindles spin freely after years of sitting
- Thin wall geometry slides right into standard drill chuck housings without custom machining
- Heat tolerant composition stops warping even during prolonged summer sanding sessions.
