Founded in 1927, Warner Electric is a global leader in the development of electromagnetic clutch and brake solutions. Warner utilizes the latest materials and manufacturing technologies to design long life, easy-to-use clutches and brakes that provide improved accuracy and repeatability. Warner Electric, now a brand of Altra Industrial Motion, offers the broadest selection of industrial clutches, brakes, controls, and web tension systems from a single manufacturer.
Basic Design Clutch Products
- PCC Primary Design Coupling Units: PCC Series clutch couplings employ the same basic components as the PC, except for a splined hub and adapter, which serves as a coupling for inline shaft applications.
- PC Primary Design: Current is carried through brushes and the collector ring to the rotating magnet. The PC design is less expensive than the SF design.
- SFC Stationary Field Design: SFC Series clutch couplings employ the same basic components as the SF design except for a splined hub and adapter, which serves as a coupling for in-line shaft applications.
- SF Stationary Field Design: The SF design eliminates collector rings and brush-holder. Ideal for adverse environmental conditions. Mounting tolerances are generally more critical than the PC design. Flange or bearing mounted styles available.
