Shear Pin Hubs

Browning® 1188259 Type 1 Shear Pin Hub, 1/2 to 1-3/4 in Dia Bore, 7/8 in Dia Hub, 7-5/8 in OD Flange, 2-1/8 in L Through Bore

Browning® shear pin hubs are designed to prevent damage to machinery due to sudden overload or jamming by shearing the necked pin at a predetermined load. The inner part of the hub is keyed to the shaft and remains stationary while the outer part, to which the sprocket is bolted, rotates freely after pin breakage, allowing the drive to idle. Shear pin hubs are ideal for heavily lubricated areas where a cost effective solutions is needed.

Browning® 1188242 Type 1 Shear Pin Hub, 3/8 to 1-1/2 in Dia Bore, 5-1/2 in OD Flange, 2-1/4 in L Through Bore

Browning® shear pin hubs are designed to shear a necked pin at a predetermined load. This protects equipment from overloads. Consisting of a hub assembly, a sprocket and shear pin, the shear pin bridges between the sprocket and hub assembly. The shear pin is available in load increments, so the closest one to your application requirements must be chosen. Resetting the shear pin hub is accomplished manually by replacing the shear pin. Best applied to applications where infrequent overloads are encountered. Torque capacity is up to 50720 in-lb.
