Air Motor LZB66 1.41-1.87 kW

Name: Air Motor LZB66 1.41-1.87 kW
Brand: Atlas Copco

LZB66 series, extreme duty air motors with stainless steel options.

Air Motor LZB66 1.41-1.87 kW

Air Motor LZB66 delivers immense power and superior performance for heavy-duty industrial applications requiring high torque and absolute reliability. This series, classified as high-capacity pneumatic air motors, is engineered to drive heavy equipment and withstand extreme working loads over long periods.

The LZB66 series offers an impressive combination of speed and torque, with models capable of generating stall torques of up to approximately 600 Nm (in low-speed versions). Featuring a hardened planetary gear system and advanced vane technology, these motors ensure smooth and efficient operation. Atlas Copco also offers this series in Stainless Steel (RL) versions, making them ideal for corrosive environments in the chemical and food industries. The vane technology allows for Lube Free operation, preventing environmental contamination and saving maintenance costs. Additionally, the motors are stall-proof and carry full ATEX certification for safe operation in explosive atmospheres. To select the perfect model for your specific requirements, use the Air Motor Selection Tool or check out our full range of Air Motors.
