Frequently Asked Questions
Q: How does a set collar differ from a split clamp collar?
A: A set collar uses one or more set screws threaded radially through the collar body to bear against the shaft, locking the collar at a specific axial position. It does not require shaft modification such as a groove or flat unless a shaft flat is present for improved retention.
Q: What is the typical function of this set collar in a gate operator?
A: Set collars are used as mechanical stops to prevent shaft components from sliding axially, as spacers to maintain gap between components, or as retention elements to keep bearings, bushings, or other parts seated on the shaft.
Q: What is the correct way to install and secure this set collar?
A: Apply thread-locking compound (medium-strength) to the set screw threads, position the collar at the correct axial location on the shaft, then torque the set screw to the Genie-specified value. Do not over-torque, as this can damage the shaft.
Q: How do I check if this set collar has loosened in service?
A: Check the set collar for axial movement on the shaft during routine maintenance. If the collar has migrated from its set position, the set screw has loosened and should be re-torqued with fresh thread-locking compound.
Q: What does the 3/4 inch dimension refer to in this part number?
A: The 3/4 inch dimension refers to the outer diameter (OD) of the collar body, which determines the overall size and the bearing face area available when the collar is used as a stop against an adjacent component.
