Blue urethane spider insert for L070 jaw coupling

Lovejoy

Lovejoy L070U Urethane Spider Insert v-belt

SKU CH-DMYA-23B2N

Urethane spider insert for L070 jaw couplings, rated 14,000 RPM and 65 in-lb torque with 90A durometer hardness

  • Urethane spider handles 65 in-lb torque for reliable power transmission
  • Rated to 14,000 RPM for high-speed coupling applications
  • 90A durometer hardness resists wear in demanding environments
  • Accommodates 0.015 in parallel and 1 degree angular misalignment
  • Fail-safe design maintains operation if spider element fails

Component Identity

This urethane spider insert is a replacement element for L070 jaw couplings used in power-transmission assemblies. It suits maintenance technicians and original-equipment builders who need a flexible, fail-safe connection between driving and driven shafts in general industrial machinery.

Decisive Specification

The insert handles a maximum torque of 65 in-lb and a top speed of 14,000 RPM while delivering 0.10 hp at 100 RPM. Its 90A durometer polyurethane body accommodates 0.015 in of parallel misalignment and 1 degree of angular misalignment, defining the vibration and alignment envelope the coupling can absorb.

Build Integration

The blue insert fits hubs bored up to 3/4 in and carries an outside diameter of 1 23/64 in, so it installs within existing L070 hub sets without changing shaft spacing. Its fail-safe design keeps torque flowing if the urethane wears, protecting connected blowers, compressors, generators or pumps from sudden decoupling.

Questions about this item

What does the 0.10 hp rating at 100 RPM mean for my machine?

The insert transmits 0.10 horsepower when the coupling runs at 100 RPM; power capacity scales with speed up to the 14,000 RPM limit.

How does the L070 coupling interface limit torque and misalignment in practice?

The L070 interface caps torque at 65 in-lb and allows up to 0.015 in parallel offset plus 1 degree angular misalignment.

What hub bore and outside diameter does this spider need to fit?

It fits hubs bored up to 3/4 in and seats in a 1 23/64 in outside diameter coupling.
