Belimo KG8 Ball Joint

The Belimo KG8 Ball Joint is a critical linkage component engineered for heavy-duty HVAC damper applications, specifically designed for use with the KH8 damper crank arm. This 5/16 inch (8.2 mm) ball joint features a 90-degree offset, providing the necessary articulation for remote actuator and damper rod connections. Manufactured from galvanized steel, the KG8 ensures long-term mechanical integrity in stationary heating, ventilation, and air-conditioning systems. It is the standard hardware solution for connecting SH8 push rods to crank arms, translating linear actuator force into precise rotational damper movement.

For technicians in the field, the Belimo KG8 is indispensable when installing or retrofitting damper linkage kits. Its robust construction resists corrosion and mechanical wear, maintaining tight tolerances to prevent play in the linkage assembly. This accessory is fully compatible with a wide range of Belimo actuator series, including the LF, NF, SF, NM, and SM families. Whether you are performing a new installation or replacing a failed joint, the KG8 provides a secure, low-friction connection point that ensures smooth damper blade positioning and reliable airflow control across the entire stroke of the actuator.

• Precision Linkage: Designed for an exact fit with the KH8 crank arm and 5/16" rods to eliminate slippage.
• Corrosion Resistance: Heavy-duty galvanized steel construction stands up to high-humidity duct environments.
• Versatile Application: Supports a 90-degree rod orientation, allowing for flexible mounting in tight mechanical spaces.
• Broad Compatibility: Engineered to work seamlessly with Belimo LF, NF, and AM series actuators as part of a complete linkage system.

What rod size is compatible with the KG8?
The KG8 is specifically sized for 5/16 inch (8.2 mm) diameter rods, such as the Belimo SH8 push rod.

Can the KG8 be used with other crank arms?
While optimized for the KH8 damper crank arm, it can be utilized in various custom damper linkage assemblies requiring a 90-degree 5/16" ball joint.

Does this joint allow for angular adjustment?
Yes, the ball and socket design allows for the necessary pivoting and rotation required to handle rod misalignment or complex linkage geometries during the actuator stroke.
