LOVEJOY SPIDER 11486

This Lovejoy SPIDER 11486 is also known as a coupling insert or element, and C1HG44 is listed as an alternate part number.

In a Lovejoy coupling, the spider is the insert or element that sits between the coupling halves to connect them. The 11486 spider is that insert component, and this one is made from Hytrel.

Hytrel is what you're getting here. It's a thermoplastic elastomer known for holding up well under flex and load cycling, so it handles the kind of repeated stress that wears out softer materials faster. For a coupling insert, the material absolutely matters since it absorbs shock and misalignment between shafts, and Hytrel does that job reliably without cracking or taking a set the way some urethane elements can.
