FAQ

Q1: What is a jaw coupling spider?
A jaw coupling spider is the elastomeric insert placed between the hubs of a jaw coupling. It transmits torque, absorbs shock, and compensates for misalignment.

Q2: Why choose PU spider inserts over rubber?
PU offers better wear resistance, chemical resistance, higher load capacity, and longer service life than rubber.

Q3: Can the spider be customized?
Yes, we offer different hardness levels, diameters, and thicknesses to fit your coupling specifications.

Q4: Which industries commonly use jaw coupling spiders?
They are widely used in automation, CNC machining, packaging, material handling, pumps, and conveyors.

Q5: How does a PU spider improve coupling performance?
It absorbs vibration and shock, reduces stress on shafts, and provides smooth torque transmission.
