Lovejoy

Lovejoy Buna-N Spider Insert L075 1 47/64 in 11000 RPM 90 in-lb 80A

SKU CH-S0XB-XF9Y1

Buna-N spider insert for L075 couplings handles 90 in-lb torque at 11000 RPM with 80A durometer

  • Buna-N material resists oil and wear
  • 11 000 RPM rating suits high-speed drives
  • 90 in-lb torque capacity handles demanding loads
  • 015 in parallel misalignment eases installation
  • 80A durometer balances flexibility and strength

Buna-N Spider Insert for L075 Couplings

This Buna-N spider insert fits L075 coupling hubs with a maximum bore of 7/8 in. It transmits up to 90 in-lb of torque and is rated for 11,000 RPM maximum speed. The insert suits industrial power-transmission assemblies that require a fail-safe elastomeric element.

Thermals, Noise and Power Draw

The 80A durometer Buna-N material dampens vibration and accommodates 1 degree of angular misalignment plus 0.015 in parallel offset. At 100 RPM the coupling transmits 0.14 hp with minimal heat buildup. No lubrication is required, so operating noise stays low and power loss is negligible in normal service.

Replaces Worn Spider Elements

This insert directly replaces a damaged or aged spider in existing L075 hub sets, restoring rated torque and misalignment capacity. The jump is worth it when vibration increases, backlash appears or the original element shows cracking. It is not for applications needing higher torque, greater speed or a different bore size than the L075 hub allows.

Questions about this item

How do I install the L075 Buna-N spider insert and what step is often missed?

Press the spider into the hub jaws until it seats fully; the step often missed is confirming the 0.015 in parallel misalignment limit after assembly.

What maintenance or replacement will the L075 spider insert need over time?

Inspect the Buna-N material for cracking or hardening; replace the spider when wear exceeds the 1 degree angular or 0.015 in parallel misalignment capacity.

What limit appears first when the L075 coupling runs continuously at high speed?

The 11,000 RPM maximum speed rating is the first limit reached under sustained operation before torque or misalignment thresholds are exceeded.
