White Hytrel spider insert for L190 coupling, 4 15/32 inch OD

Lovejoy

Lovejoy L190 Hytrel Spider Insert 190 55D 4680 in-lb 7.4 hp 5000 RPM

SKU CH-1C18-6D8QT

Hytrel spider insert for L190 jaw couplings rated 4,680 in-lb torque at 5,000 RPM

  • Hytrel spider rated for 4,680 in-lb maximum torque
  • Operates up to 5,000 RPM for high-speed drives
  • 4 hp capacity at 100 RPM reference speed
  • 55D durometer resists wear in crane and mill service
  • Fail-safe design maintains drive if spider fails

L190 Hytrel Spider Insert

This L190 coupling insert is made from Hytrel with a 55D durometer hardness. It fits hub bores from 3/4 in to 2 1/8 in and has an outside diameter of 4 15/32 in. The white insert is designed for power transmission in equipment such as cranes, generators and mills.

Fail-safe design with misalignment tolerance

The insert provides fail-safe operation and accommodates parallel misalignment of .015 in and angular misalignment of .5 degrees. These allowances help protect connected machinery from vibration and shaft alignment errors during operation.

4680 in-lb maximum torque rating

The single specification that decides fit is the maximum torque of 4680 in-lb at 5000 RPM with 7.4 hp at 100 RPM. Select this insert only when your application demands this exact torque capacity and speed limit.

Questions about this item

How often should the Hytrel spider insert be inspected or replaced in a crane application?

The Hytrel spider is a wear component; inspect it during scheduled downtime and replace it if cracking, excessive deformation or loss of torque capacity is observed.

At 5,000 RPM continuous operation, does torque capacity or misalignment tolerance become the limiting factor first?

The insert is rated for 4,680 in-lb maximum torque and 0.5 degree angular misalignment; sustained operation near either limit will accelerate wear, so monitor both vibration and temperature.

What temperature rise and noise level should be expected when the coupling runs all day at 5,000 RPM?

Hytrel material dampens vibration, reducing noise compared to metal inserts; normal operation stays within the 55D durometer range, but exact temperature rise depends on load, alignment and ambient conditions.
