KYB (Kayaba) MAG Hydraulic Travel Drive Motor MAG-33V, MAG 33 VP And Rexroth GFT Crawler Excavator

KYB drive motors are a high torque and high efficiency travel motor specifically designed for crawler machines. The drive motors can be customized to fit the customer's requirements with many different ratios and displacements available.

Features

The piston motor has a variable displacement (2-speed) swashplate and incorporates a brake valve and mechanical brake. Combined with a case-rotation type planetary gear reducer, the KYB drive motor offers the following outstanding features:

•Hydraulically balanced piston motor ensures high-pressure high-performance operation.
•An offset-type 2-speed design ensures reliable changeover of the displacement by an external pilot control (speed ratios of between 1.5:1 and 2:1)
•The motor offers a built-in double counterbalance valve and shockless crossover relief valve, providing speed control and braking with minimum shock.
•The mechanical brake is a negative brake linked with the counterbalance valve. The brake is automatically activated or released when the vehicle stops or starts.
•The case-rotation type gear reducer has improved durability and reliability due to high precision parts and an equally-loaded design.
•The motor uses heavy duty bearings to ensure long life. Floating seals also prevent dust or water from entering into the motor.
