What is the purpose of a SPIDEX coupling?
A flexible coupling connects two shafts, end-to-end in the same line, for two main purposes. The first is to transmit power (torque) from one shaft to the other, causing both to rotate in unison, at the same RPM. The second is to compensate for minor amounts of misalignment and random movement between the two shafts

What is the real name of spider coupling?
Jaw couplings
Jaw couplings are composed of three parts: two metallic hubs and an elastomer insert called an element, but commonly referred to as a "spider".

What material is used for spider coupling?
Image result
Nitrile butadiene rubber (NBR)

Buna N, as it's often called, is the most economical and widely used spider material. It has much in common with natural rubber with its resilience and elasticity

What size is spider coupling?
Spider (Coupling insert) standard 98 Shore A red size 24 outside diameter 55mm SKU: 60509824. Material: Polyurethane, shore hardness 98° A (medium hard), red.

What is the difference between Oldham and spider coupling?
As in the oldham coupling, there is a press fit between the jaws and the spider for the coupling to deliver zero backlash. In contrast to the oldham coupling, where the torque disk is in shear under torsional loads, the jaw coupling's spider operates in compression

Which coupling is used for high speed?
Image result
SFM couplings are designed for high-speed power transmission applications up to 24,000 rpm where high torque and precision alignment is critical. Available in 10 sizes, SFM couplings transmit torque by connecting two shafts while damping system vibrations and accommodating misalignment.

What are the two types of shaft couplings?
Image result
Couplings can be categorized as rigid or flexible types. Rigid coupling connects two shafts that are precisely aligned and handling high-torque loads while flexible couplings connects two shafts that are less precisely aligned and handling from low-torque to moderate-torque loads.
