LOVEJOY L Type Spiders, Solid Centers
Lovejoy L type coupling spiders are used when shafts of the driver and driven equipment are required to be kept partitioned by a standard gap. These fail-safe Lovejoy spiders are used with L type keyway hubs to prevent relative movement or extremely close (near touching) shaft separation, makin...g them resistant to dirt, sand, oil, moisture & grease. These closed centre units have a robust design and are desirable for high speed applications. Raptor Supplies also offers L type open centre spiders for heavy-duty applications.Read more

Frequently Asked Questions
What is the primary purpose of the clearance or gap between the key and the keyway?
The purpose of providing some gap or clearance between the key and the bottom of the hub keyway is to ensure that the hub seats properly on its shaft. In the case of a coupling hub, this clearance causes damage to its internal surfaces as it provides an opening through which corrosive gases or water can enter the coupling easily.
What is the difference between keyway and without keyway hubs?
A keyed connection ensures a positive stop until failure. On the other hand, if the two mating parts are not assembled correctly or the torque gets exceeded, a keyless connection in hubs could permit slippage between them. Hubs without keyways prevent parallel and angular shaft misalignment.
What is a spider in a coupling?
Lovejoy jaw couplings are composed of three parts, i.e. an elastomer insert known as a spider and two metallic hubs on both sides. These three separate parts are pressed together with the help of a jaw from each hub, both of which are fitted alternately with the lobes of the spider to form a Lovejoy spider coupling.
