Belimo K6 Clamp

The Belimo K6 Clamp is a heavy-duty shaft clamp reversible assembly engineered specifically for LF series spring-return actuators. Designed to provide a secure mechanical connection in high-demand HVACR environments, this standard LF clamp facilitates direct-coupled mounting on damper shafts ranging from 3/8 inch to 1/2 inch (10 to 13 mm) in diameter. For technicians dealing with larger jackshaft applications, this component ensures the 35 in-lb torque of the LF actuator is efficiently transferred without slippage.

Constructed from high-grade galvanized steel, the Belimo K6 is the industry standard for maintaining damper actuator compatibility across various air handling unit (AHU) and terminal unit configurations. Its reversible nature allows for flexible installation on either side of the actuator housing, accommodating both clockwise and counter-clockwise fail-safe requirements. As a critical actuator accessory, it maintains a precise grip to prevent mechanical play, ensuring accurate positioning for proportional and on/off control sequences.

• Universal Compatibility: Specifically milled for the Belimo LF series, ensuring a perfect fit for 3/8" to 1/2" shafts.
• Reversible Design: Simplifies field installation by allowing the clamp to be mounted on either side of the actuator for CCW/CW rotation.
• Durable Construction: Galvanized steel build resists corrosion in harsh mechanical room environments and plenum spaces.
• Precision Grip: V-bolt design provides maximum surface contact to eliminate shaft slippage during high-cycle operation.
• Direct Mount Integration: Streamlines the mounting process for dampers, reducing the need for additional linkages or brackets in standard applications.

Can the K6 clamp be used on round and square shafts?
Yes, the V-bolt architecture is designed to securely grip both round shafts and square shafts within the 3/8" to 1/2" size range.

What is the difference between the K6 and the K6-1 clamp?
The standard K6 clamp is sized for shafts up to 1/2", whereas the K6-1 is the oversized variant designed for 1/2" to 3/4" shafts, often required for larger jackshaft clamp applications.

Does this include the retaining clip?
This product includes the primary metal clamp and V-bolt assembly; however, verifying the presence of the side-locking retainer clip is recommended if you are replacing a damaged unit.
