The Torqmax coupling has impressive quality features. Its bores are precisely honed in a final working process. As a result, the Torqmax coupling ensures highest surface quality and standards in terms of dimensional tolerance and geometrical accuracy. The high-quality screws DIN 912, quality 12.9, are treated with a special Nypatch^® process. Nypatch^® is a proprietary process that involves depositing a 360 degree coating of Nylon on several threads of the socket head cap screws. This coating is designed to reduce screw vibration, which can cause the screws to loosen and torque transmission ability to diminish during the course of normal use. The Nylon also provides the necessary dissimilar material to reduce galling of the screw threads in stainless steel rigid couplings.

For heavy duty applications with highest torque requirements the series Torqmax Heavy Duty is the ideal coupling solution. The series is available with bore diameters ranging from 55 to 100 mm with or without keyways. The two-piece design has the additional benefit of allowing for disassembly and maintenance without removal of other components. Torqmax Heavy Duty are made of carbon steel with black oxyd-finish, versions in stainless steel are available upon request additionally.
