If you are looking for a cold-install hub that provides the secure torque transmission and balance repeatability of an interference fit, check out the Torsiflex-i flexible disc couplings. Developed for API 610 service, these couplings feature a robust disc pack design, allowing for greater torque load in a smaller, lower weight size. Max bores matched to NEMA motor shafts provide up to a 60% weight savings. A plug-in spacer design allows installation and removal without disturbing the hubs. All models are ATEX compliant and come standard with a zinc phosphate coating, a built-in anti-flail feature, and inch series hub attachment screws (metric available).
These couplings are now available with Torsi-Lock® Hubs, which offer the ease of a slip fit with the power of a shrink fit.
Cold installation of Torsiflex-i couplings with Torsi-Lock Hubs means no hot work permits, providing added safety and productivity in hazardous environments.
Torsi-Lock hubs provide easy, repeatable removal and installation, and eliminate fretting of hub to shaft. The hubs compensate for variances in shaft spacing – units can be slipped on and fixed in the needed location. The Hub and locking device are balanced and match-marked to assure optimum balance performance.
