FAQ

Question?
What is the difference between the black Buna-N spider and other colors like blue or red?

Answer

The black spider is made from Buna-N (NBR), which is the standard material offering good oil resistance and damping properties. Other colors typically indicate different materials. For example, blue or red spiders are often made of Urethane, which offers a higher torque capacity and better wear resistance but less damping capability.

Question?
How do I know if the L-075 spider is the correct size for my coupling?

Answer

The L-075 designation refers to the specific size of the coupling hub it fits. You must match the spider size to the coupling hub size (e.g., L-075 hubs). The overall diameter of an L-075 spider is approximately 1.76 inches (44.7 mm). Always verify your hub’s model number before ordering.

Question?
What are the signs that a coupling spider needs to be replaced?

Answer

Signs of wear include visible cracks, deformation, or hardening of the elastomer. You might also notice increased vibration, noise, or backlash (play) in the coupling during operation. Regular inspection is recommended, especially in critical applications.
