KMC Controls HLO-1016 Collar

The KMC Controls HLO-1016 Collar is a precision-engineered actuator accessory designed to ensure a non-slip, secure connection between actuators and shaft-driven HVAC equipment. This retaining collar is specifically optimized for use with 1/2-inch round or 3/8-inch square shafts, providing the high-torque stability required for consistent damper and valve positioning. As a critical component for shaft adapter alignment, the HLO-1016 prevents mechanical drift and maintains the integrity of the linkage in building automation systems. Built for durability in demanding commercial environments, these collars are typically used in conjunction with the HLO-1006 drive bushing to facilitate seamless direct-coupled actuator integration. For contractors managing large-scale mechanical retrofits or new installations, this shaft locking collar offers the reliability needed to prevent costly call-backs caused by linkage slippage. By utilizing a robust design that accommodates multiple shaft geometries, the KMC HLO-1016 streamlines field installation and ensures energy-efficient airflow control across the entire air handling unit.

• Universal Compatibility: Engineered to fit both 1/2" round and 3/8" square shaft profiles for maximum field versatility.
• Mechanical Stability: Provides a high-friction retaining connection that eliminates actuator slippage during high-torque transitions.
• Seamless Integration: Designed for exact fitment with KMC HLO-1006 bushings and various damper shaft adapters.
• Durable Construction: Manufactured from industrial-grade materials to withstand the continuous cycling of HVAC actuators.

What compressor or actuator shafts does the HLO-1016 support?
This collar is specifically intended for 1/2" round or 3/8" square shaft adapters, commonly found on KMC and third-party damper actuators.

Can this be used as a standalone shaft lock?
While it provides significant clamping force, it is optimized as a retaining collar for shaft adapters to ensure the actuator drive remains centered and secured.

Does the HLO-1016 help with alignment issues?
Yes, by providing a uniform clamping surface, it helps maintain the axial alignment of the shaft within the adapter, reducing wear on the actuator's internal gears.
