Belimo KG10A Ball Joint

The Belimo KG10A Ball Joint is a critical hardware component engineered for high-torque HVAC linkages, providing a 3/8 inch (10mm) straight connection between crank arms and damper shafts. Constructed from durable zinc-plated galvanized steel, this damper accessory is purpose-built to withstand the mechanical stresses of commercial air handling applications. It serves as a direct replacement for the legacy KG10 model and is specifically designed to integrate with KH8 and KH10 damper crank arms. As an essential part of an actuator linkage kit, the KG10A ensures smooth force transmission across a wide range of motor series, including the Belimo NM, AM, GM, and LF lines. For technicians performing HVAC damper repair, this ball joint offers the precise fit required to eliminate slop in the linkage, maintaining accurate blade positioning and system pressure control. Its robust material composition prevents corrosion in stationary heating and cooling environments, making it a reliable choice for long-term field installation.

• Precise Compatibility: Engineered specifically for use with KH8 and KH10 universal crank arms, ensuring a zero-play mechanical connection.
• Industrial Durability: Fabricated from zinc-plated steel to resist oxidation and structural fatigue in high-duty cycle damper assemblies.
• Universal Rod Seating: Designed to accommodate standard 3/8" (10mm) diameter rods, facilitating rapid field adjustments and retrofits.
• Broad Actuator Support: Verified for use across multiple Belimo actuator series, including LM, NM, AM, GM, and spring-return NF/AF units.

Which crank arms are compatible with the KG10A?
The KG10A is designed to fit the KH8 and KH10 crank arm models. It is frequently used in damper linkage assemblies where a straight 3/8-inch connection is required for proper alignment.

Is the KG10A suitable for outdoor or high-moisture environments?
While the zinc-plated steel construction provides excellent resistance to standard mechanical wear and moderate humidity, it is primarily intended for stationary HVAC systems. Always verify the specific environmental ratings of the associated actuator and housing.

Can I use this for 5/16" rods instead of 3/8"?
No, the KG10A is sized specifically for 3/8 inch (10mm) rods. For 5/16" (8mm) applications, technicians should typically look toward the KG8 or KG6 series to ensure a secure mechanical fit.
