Benefits of Series XTSR

Optimal Sizing Lowers Upfront Costs

With available standard XL & XXL hub options, shaft size is practically eliminated as a limitation in coupling selection, allowing the most economical coupling size selection based on application torque.

Low Coupling Weight Extends System Life

The increased torque-density delivers exceptional performance within smaller physical package. The resulting lower coupling weight reduces loads on bearings and other connected equipment, extending system life.

Standard Features Simplify Assembly & Installation

Fully-unitized disc packs and tapered lead bolts eliminate common assembly challenges typical of other manufacturers’ couplings. The pre-assembled XTSR71 center assembly enables fast installation without moving hubs or connected equipment.

Modularity Reduces Inventory Costs

Disc packs, hardware, and other components are shared across the entire XTSR platform, reducing spare parts inventory requirements.
