Single Row One Way Clutch Bearing Housing Unit
✔️ 20mm Bore X 42mm OD X 14mm Width Grease Packed Design

This single sleeve bearing assembly acts as a handy one way roller clutch mechanism designed to keep conveyor drums, free wheel idlers, and backstops spinning freely in a single direction while locking against reverse torque. Mechanics typically drop these units onto heavy duty transport frames and industrial mixers where reliable directional control stops unwanted spin backs and protects drive shafts from shock damage during daily runs.

✅ Sprag inserts measure 20mm 0.78in diameter fitting standard 42mm 1.65in outer rings
✅ Holds C clearances for tight rotation across 14mm 0.55in width specifications
✅ Blocks dust bigger than 0.3mm 0.012in using factory packed grease seals
✅ Survives temperature swings from minus 6 to plus 60 Celsius 21 to 140 Fahrenheit
✅ Locks onto n six shaft diameters and presses into matched K six housing bores

💡 How do you safely mount and maintain a one way sprag clutch bearing for lasting performance?
Choosing correct fit tolerances ensures the internal races engage smoothly without binding under load. This simple setup choice keeps your machinery handy and stops premature wear on driving tracks. Apply fresh grease before pressing the unit onto the shaft to avoid early friction hot spots,
Snap protective nylon covers onto exposed faces whenever plant humidity stays above fifty degrees Celsius 122 Fahrenheit,
Monitor surface temperature closely to ensure it never crosses one hundred forty degrees Fahrenheit 60 Celsius continuously.✝️
