Browning SHP1 Shear Hub, 1340-14950 in-lbs
Browning SHP1 shear hub. Rated at 1340-14950 IN-LBS, 1/2" to 1-3/4" bore. Use as a mechanical over-torque limit device thru the use of a shear pin. Use with P1 bushing.
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.
Browning shear pin hubs and sprockets consist of three separate stock parts:
- Steel sprockets
- Hub assembly
- Malleable bushing
Each part is individually packaged. The hub assembly includes sprocket mounting bolts, two hardened liners and one minimum strength shear pin. Additional liners and shear pins are available from stock in a wide range of shear strengths. Sprockets are available in pitches and numbers of teeth shown on page 85, machined to fit shear pin hubs. Stock Browning type ďAĒ sprockets
with other numbers of teeth can be machined to fit these hubs. Bushings are stock Browning split taper bushings. Both Type 1 and Type 2 shear pin hubs are grease packed to provide low friction rotation in case of pin breakage.
Type 2 hubs are provided with a grease fitting for re-lubrication.
