In the role of a mechanical safeguard, a shear pin is a safety device designed to shear in the case of a mechanical overload, preventing other, more expensive or less-easily replaced parts from being damaged. As a mechanical sacrificial part, it is analogous to an electric fuse.

Use with shear hubs to break at a specific torque and safeguard machinery from overloads. Align parts before assembly or use as a pivot, shaft, or hinge to join moving components. Choose from our selection of pins for shear hubs, dowel pins, pull-out …

GEARBOX shear pin / 15 spline output. Gearbox used on some of the 6, 7, 8 and 10 foot cutters. Smooth Input Shaft with 15 Spline Output Shaft Longer output shaft (approx 6") Measure accross the output shaft, for the bolt circle. It should be approx. 8” Available Parts...

Sep 6, 2012 · Background: To prevent too much torque having to be transmitted through the gearbox on a gate valve, a shear pin is to be fitted between the hand wheel and the gearbox spindle. When a certain torque is reached the pin should rupture and no torque transmitted. See attachment for reference diagram.

Spring Pin to afix a hub or gear to a shaft is the Coiled Pin’s ability to prevent hole damage. Another benefit is that the Coiled Pin absorbs wider hole tolerances than any. other press-fit pin. This translates to lower total manufacturing costs of the assembly.

The Shear Pin Cartridge coupling is a Series H type coupling designed to physically disconnect the driving and driven equipment during torque overload. The purpose of this design is to prevent damage to the equipment - motor, gearbox, pump, etc. - from torque overload.
