Shaft Couplings

Shaft Couplings

Anti-Backlash Nuts offer adjustable drag torque.

Designed to optimize system stiffness without increasing drag torque, T Series (torsional style) Anti-Backlash Nuts eliminate clearance between threads of nut and threads of leadscrew. Products utilize blend of self lubricating polyacetal in conjunction with precision rolled 303 stainless steel screw material. Requiring one-time lubrication, torsional style nuts can also run dry when used with...

Shaft Couplings

17-4PH St ainless Steel Provides Twice the Torque Capacity

SANTA MARIA, CA., March 6, 2006-Helical's 17-4PH stainless steel couplings are ideal when high strength, excellent fatigue resistance and high torsional stiffness are called for in an application. When compared to both 303 stainless steel and 7075-T6 aluminum, 17-4PH provides twice the torque. Helical is the only company that claims to manufacture beam couplings out of 17-4PH stainless steel....
