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.

PTO Clutches

  • PC (Primary Clutch) design requires a brushholder to carry current from the power source to the rotating magnet.
  • SF (Stationary Field) clutch design consists of a bearing mounted magnet assembly, or field, a rotor assembly, and an armature assembly.
  • CMS 250 Series Commercial MagStop clutch/brakes are designed for heavy-duty mowers.
  • Commercial MagStop clutch/brakes for heavy-duty mowers for large grounds maintenance requirements.
  • GT300 clutch/brake model features a triple-groove pulley to accommodate multiple v-belts.
  • BBC-II Blade Brake Clutches (BBCs) are engaged by actuating the operator presence lever and pushing the blade engagement handle.
  • Residential MagStop (RMS) clutch/brakes for mower decks and other implements controlled by a dashboard switch.
  • TG2000 incorporates the features of the Commercial MagStop clutch/brakes into a design specifically for tractors.
