Lovejoy AL095 1/2" Jaw Coupling Hub Aluminum NK

SKU CH-B85G-8J6VJ

Aluminium jaw coupling hub with 1/2 in bore, 9 000 RPM limit and set-screw locking

  • Lightweight aluminium hub reduces rotating mass
  • 9000 RPM rating suits high-speed drives
  • 1/2" round bore with set-screw locking
  • Three spider choices give .31, .47 or .89 hp at 100 RPM
  • Straight jaw profile fits L095 Buna-N, Urethane and Hytrel elements

Coupling Hub for 1/2 in Shafts

This aluminum jaw coupling hub fits a 1/2 in round bore and uses a set screw for shaft locking. It is designed for power transmission systems that require a straight jaw profile and inch measurement standards.

Rated for 9,000 RPM Maximum Speed

The hub operates at up to 9,000 rpm with an outside diameter of 2 7/64 in and an overall length of 2 1/2 in. Horsepower at 100 rpm varies by spider material: 0.31 hp with Buna-N, 0.47 hp with urethane, and 0.89 hp with Hytrel.

Sustained Load with Compatible Elements

Under continuous operation the hub works with L095H, L095N, or L095U center elements secured by a 5/16 in -18 NC set screw. It is not suited for applications that exceed the stated speed or horsepower ratings for the chosen spider material.

Questions about this item

How do I install the AL095 hub on a 1/2" shaft and which step is often missed?

Slide the hub onto the shaft, align the keyway if present, then tighten the 5/16-18 NC set screw to lock it; the step often missed is torquing the set screw to the manufacturer's specified value to prevent loosening under vibration.

What maintenance or replacement will this hub need over time?

The aluminum hub itself requires no scheduled maintenance, but the compatible L095N, L095U or L095H center element (spider) wears and must be replaced periodically; inspect the spider for cracking or deformation during routine checks.

At 9,000 RPM sustained, what limit appears first?

The 9,000 RPM maximum speed rating is the first hard limit; exceeding it risks hub failure regardless of the 0.31 hp (Buna-N), 0.47 hp (Urethane) or 0.89 hp (Hytrel) torque capacities at 100 RPM.
