BELOIT, Wis.—Regal Beloit Corporation, a leading manufacturer of electric motors, electrical motion controls, power generation and power transmission components, announced it will debut the next generation of its SealMaster Skwezloc Locking Collar concentric locking collar at 2017 Pack Expo Las Vegas beginning September 25, 2017.

The new design accommodates commercial turned and polished shafting while improving lock reliability on turned ground and polished shafting.

The Skwezloc Locking Collar achieves improved lock reliability through an innovative circumferential groove on its inner ring bore that reduces stress on the inner ring when properly clamped to the shaft. A larger cap screw and collar also improve the clamping force and holding power to the shaft.

“Through extensive research, we found that the overwhelming majority of our customers prefer concentric locking for ease of installation, but needed a design that meets customer shaft tolerances,” says Regal Beloit Corporation director of marketing Ian Rubin. “By reducing the stress on the inner ring and adding a groove that decouples from the inner ring to improve elasticity, we’ve arrived at a design that meets the customer shaft tolerance need, especially for customers in the warehouse distribution, parcel distribution and baggage handling industries.”

The next generation Skwezloc Locking Collar also reduces stress concentrations when the collar is tightened through an optimized chamfer profile. It maintains the same simple single-screw installation of preceding models that prevents axial movement while also eliminating the risk of preloading the bearing.
