Belimo K-AM25 Standard Clamp

The Belimo K-AM25 Standard Clamp is a critical mechanical accessory for securing NKQ, AM, and NM series actuators to damper shafts in commercial HVAC systems. This reversible clamp is engineered to accommodate shaft diameters ranging from 1/2 inch to 1.05 inches, providing a high-torque, non-slip connection for both square and round jackshafts. Built from nickel-plated cold rolled steel, the K-AM25 ensures long-term structural integrity and corrosion resistance in demanding mechanical room environments.

For technicians performing field retrofits or new installations, this actuator hardware offers a universal fit that eliminates the need for multiple specialized adapters. The V-bolt design allows for rapid centering and tightening with a 10mm wrench, maintaining alignment and preventing the "play" that leads to premature linkage failure. Whether you are replacing a standard damper clamp or upgrading an existing Belimo actuator, the K-AM25 provides the direct-coupled reliability required for precise airflow control and tight damper close-off.

Key Benefits

• Universal Compatibility: Fits shafts from 1/2" to 1.05", making it a versatile tool for NKQ, AM, and NM series actuators.
• Industrial Durability: Constructed from nickel-plated steel to resist oxidation and withstand high-torque applications.
• Field Reversible: Engineered for easy reversible mounting to accommodate different damper rotation directions (CW/CCW).
• Secure Grip: The standard clamp design features a robust V-bolt to ensure a positive lock on the jackshaft without slipping.
