Heavy Duty Carbon Steel Sleeve Bearings 2 Pack Gcr15 Plain Bushings 40x45x17mm Rock Solid For Smooth Rotating Shafts And Precision Tooling Guides With Slick Self Lube Coating
✔️ Gcr15 Carbon Steel Plain Bushing 40mm x 45mm x 17mm Low Friction
These heavy duty sleeve bearings pack two pieces of Gcr15 forged steel designed to support rotating shafts in demanding setups. You will find them handy inside automotive engines, industrial presses, and woodworking tooling where smooth motion under heavy loads matters most. The self-lubricating surface cuts down on drag so your machine parts spin freely without constant greasing trips.
✅ Material composition uses GCr15 high carbon chrome steel for tough wear resistance✅ Outer diameter measures 45 millimeters while inner hole sits at 40 millimeters tall
✅ Overall height spans exactly 17 millimeters across the cylinder shell
✅ Surface treatment provides a slick factory lubricant layer to slash friction
💡 What variables dictate optimal clearance settings for linear motion guide rails? Selecting the proper gap keeps vibration down when you push heavy fixtures along track paths.
Follow these handy tips to lock in reliable performance.
- Measure actual shaft diameter before dropping in the sleeve to dodge interference friction
- Watch RPM limits closely since higher turnover demands tighter radial gaps for stability
- Monitor wear patterns along the barrel wall since dry contact areas show early fatigue signs
