Belimo K-LM16 Clamp

The Belimo K-LM16 Clamp is a specialized mechanical accessory engineered for precise air flow control in commercial HVACR systems. Specifically designed for non-spring return actuators within the LMB, NMB, and AMB series, this 5/8-inch standard clamp provides a rigid, slip-free connection to damper shafts. As a veteran technician, you know that actuator shaft compatibility is non-negotiable for maintaining BAS system integration and ensuring consistent damper assembly performance. This heavy-duty silver metal clamp features integrated teeth for maximal grip on 5/8" diameter components, preventing the positioning drift that often plagues inferior generic hardware.

Installation of the Belimo K-LM16 is streamlined for field efficiency. Using a 10mm wrench or socket, contractors should apply 6-8 ft-lb of torque to the V-bolt nuts to ensure a secure lock. For optimal results in HVAC duct applications, verify that the damper is in its fail-safe position before tightening. This component is compatible with a wide range of mounting brackets and shaft extensions, making it a staple for HVACR damper repairs and new construction damper motor installation projects. Its rugged construction excels in both indoor and shielded outdoor environments, supporting 95-degree rotation requirements for modern air handler unit (AHU) maintenance.

• Specifically engineered for Belimo LMB(X) series actuators to ensure a factory-standard fit.
• Supports 5/8" diameter shafts, providing a high-torque connection for large damper assemblies.
• Toothed metal design eliminates mechanical slippage during HVAC actuator motor operation.
• Durable construction maintains alignment in high-cycle VAV terminal unit applications.
• Includes the necessary silver metal clamp and orange plastic retainer for immediate field deployment.

Is the K-LM16 compatible with 1/2" or 3/4" shafts?
No, this specific model is optimized for 5/8" (16mm) shafts. Use the K-LM12 for 1/2" shafts or the K-LM20 for 3/4" diameter applications.

Can I use this clamp on spring-return actuators?
The K-LM16 is primarily cataloged for the LM, NM, and AM non-spring return series. Consult the actuator technical data sheet to verify manual override and shaft engagement compatibility for other series.

What tool is required for securing the nuts?
A standard 10mm wrench or socket is required. Technicians should follow the 6-8 ft-lb torque specification to prevent overtightening the V-bolt.
