SPIDEX claw coupling hub B 38/45, aluminium

HV71005350

The SPIDEX claw coupling hub B 38/45 by R+L HYDRAULICS is a precision-engineered Hub B component, built for reliable torque transmission in mid-range drive systems that demand low mass and high rotational stability. Made from die-cast aluminium, it offers excellent mechanical strength while minimizing total system weight.

With a coupling size of 38/45, this hub is rated for up to 380 Nm torque, making it ideal for pumps, processing machinery, and compact industrial drives. It supports bore diameters from Ø14 mm H7 up to Ø38 mm H7, ensuring compatibility with a broad range of shaft sizes. The hub has a length of 114 mm, which maintains secure, damped engagement with elastomer elements, reducing vibration and extending system life.

As a Hub B, this component is specifically designed to be paired with a matching Hub A, available under the accessories tab below, forming a complete, reliable, vibration-damping coupling solution within the proven SPIDEX system.
