SKU CH-YZ83-ER3G0

Carbon-steel jaw hub with 3/4 in bore and set-screw locking for L070 couplings, rated to 14,000 RPM

  • 3/4 in bore fits standard shafts
  • Carbon steel hub resists wear at 14,000 RPM
  • Set-screw locking holds hub securely
  • Compatible with Buna-N, Urethane or Hytrel spiders
  • Delivers up to 0.18 hp at 100 RPM

L070 Jaw Coupling Hub

This L070 jaw coupling hub connects two shafts in power-transmission systems. It fits a 3/4 inch round bore with a standard keyway and secures with a set screw. Carbon-steel construction suits general industrial machinery applications.

Straight Jaw Profile Compatibility

The straight jaw profile accepts L070H Buna-N, L070N Urethane and L070U Hytrel center elements. Selecting the spider material sets the torque rating and vibration damping for the specific drive. No additional hardware is required beyond the chosen element.

Rated to 14,000 RPM

Maximum rotational speed is 14,000 RPM. At 100 RPM the hub transmits 0.069 hp with a Buna-N spider, 0.1 hp with Urethane and 0.18 hp with Hytrel. Sustained operation stays within these limits when the correct element is installed.

Questions about this item

What maximum RPM can the L070 hub sustain before it becomes the limiting factor?

The hub is rated for a maximum speed of 14,000 RPM, which is the primary mechanical limit during sustained operation.

How much heat does the hub itself generate when running continuously at load?

The steel hub does not generate measurable heat; temperature rise comes from the flexible spider element, which varies by material choice.

Which centre element part numbers are required to complete the L070 coupling assembly?

Compatible centre elements are manufacturer part numbers L070H, L070N and L070U.
