Built Like A Tank Urethane L Jaw Coupling Insert For Motor Shafts With Rock Solid Flex And Zero Slack Vibration Control In Hot Rod Red Fits 0.8 Inch Bore And 1.7 Inch Industrial Parts

Heavy duty urethane L jaw coupling insert for motor shafts
✔️ 1pc red urethane coupling fits 0.8 inch bore plus 1.7 inch OD

This 1pc urethane jaw coupling insert replaces worn flexible centers in heavy duty L‑jaw couplings. You mount it directly into machinery drives, conveyor belts, pumps, and other rotating gear that requires smooth torque transfer. The split spline shape drops into place quickly so your maintenance stays hassle free.

✅ Urethane construction delivers tough flexibility and dampens vibration across your drive train
✅ Inner diameter measures 19.6 mm while the outer span reaches 44 mm for solid shaft alignment
✅ Center thickness sits at 11 mm to maintain torsional rigidity during continuous high load operations
✅ Split spline geometry locks securely inside standard L jaw housings for reliable power transmission

💡 What benefits do flexible jaw coupling inserts provide for rotating industrial equipment?
Flexible center replacements reduce wear on critical drive components and improve overall system reliability.

- Shock absorption limits mechanical stress during sudden acceleration changes
- Misalignment compensation prevents binding and causes less heat buildup in locked shafts
- Durable elastomer composition withstands constant rotational speed without crumbling
