L Jaw Couplings – Elements
TransDrive L-Type closed centre jaw coupling elements, also known as spiders are durable elastomer components designed to transmit torque while compensating for minor shaft misalignments. Operating under compression, these elements provide effective vibration damping and shock absorption, helping to protect connected equipment and enhance performance. Available in a range of designs and hardness levels, they can be tailored to suit specific application requirements across a variety of industrial environments.
Element Type
Nitrile Butadiene Rubber (NBR)
The NBR, the standard acts like natural rubber in resilience and elasticity.
- Oil-resistant
- Highly flexible
- Operating temperature -40° to 100° C (-40° to 212° F)
Polyurethane (PUR)
The PUR tolerates higher torque and is more resistant to oil and chemicals.
- 1.5x times the torque capacity of NBR
- Resistant to oil and chemicals
- Operating temperature -34° to 71° C (-30 TO 160° F)
hytrel (HYT)
HYT Elements are engineered to excel in applications requiring resistance to extreme temperatures and high torque.
- High torque
- High temperature
- Operating temperature -51° to 121° C (-60° to 250° F)
