Mounting Method
Standard 2-bolt / 4-bolt SAE flange mounting; optional oval flange.
Available with keyed, splined or tapered output shaft.
Can be installed on wheel hubs, gearboxes and equipment frames.
Keep coaxial alignment between output shaft and coupling to avoid excessive radial and axial load.
Mounting base needs sufficient rigidity to prevent vibration under pressure impact.

Application Range
Widely applied in sweepers, lawn mowers, harvesters, feed mixers, small conveyors, augers, winches, rotary tillers and other agricultural, sanitation and light construction machinery.
