Belimo K-SA Reversible Clamp

The Belimo K-SA Reversible Clamp is a critical mechanical accessory designed for HVAC damper actuators, providing a secure and adaptable interface for shaft diameters ranging from 5/8 inch to 3/4 inch (10 to 20 mm). Engineered specifically for high-torque applications, this reversible actuator clamp is compatible with Belimo SM..A, NKQ..A, and NMQ..A series actuators, ensuring a slip-free connection even in demanding airflow environments. By allowing for non-direct mounting and flexible orientation, the K-SA simplifies field replacements and new installations where shaft access is limited or non-standard. The heavy-duty V-bolt construction and serrated grip surface provide maximum engagement with the damper shaft, maintaining precise positioning and preventing mechanical drift over time. This shaft clamp accessory is the professional choice for contractors looking to ensure long-term reliability in commercial air handling units and VAV systems.

• Universal Compatibility: Optimized for 5/8" to 3/4" damper shafts, fitting a wide range of standard commercial HVAC hardware.
• Reversible Design: Allows for flexible mounting on either side of the actuator to accommodate varying CW or CCW rotation requirements.
• Precision Grip: Features a high-strength universal V-bolt that secures the actuator to the shaft without the risk of slippage under full torque loads.
• Streamlined Installation: Designed for rapid field attachment, reducing labor time during actuator retrofit or maintenance cycles.

• Which actuator models work with this clamp? The K-SA is specifically designed for Belimo SM, NKQ, and NMQ series actuators. Verify your actuator prefix before ordering.
• Does this clamp support square shafts? Yes, the reversible clamp design effectively grips both round and square damper shafts within the 10mm to 20mm range.
• What is the recommended torque for the V-bolt nuts? For a secure fit, tighten the 10mm nuts to approximately 6-8 ft-lb to ensure the serrated edge properly bites into the shaft.
