Import Cat320 Swing Motor — Buy in wholesale FOB from Supplier in China

The CAT320 Swing Motor is a hydraulic rotary actuator designed for use in Caterpillar CAT320 excavators, replacing the original equipment unit with direct-fit compatibility. It operates at a nominal pressure of 210 bar and delivers a torque output of 1,850 Nm, matching the OEM specification. The motor housing is forged from high-strength cast iron with internal gear sets machined to precise tolerances, ensuring smooth rotation under heavy load. This unit is not a generic aftermarket part but a direct replacement built to the same dimensional and performance standards as the original Caterpillar assembly.

The internal components include a piston assembly with hardened steel vanes, a ceramic-coated rotor, and a sealed gear train lubricated with synthetic hydraulic oil. These materials are typical for industrial swing motors used in medium to heavy excavators, where thermal stability and resistance to particulate contamination are critical. The output shaft features a splined interface matching the CAT320 slew ring, with a keyway and bolt pattern that aligns exactly with the OEM mounting flange. No modifications are required for installation.

This swing motor is purchased by repair shops, fleet operators, and heavy equipment distributors across Southeast Asia, Africa, and Latin America who require reliable replacements for worn or damaged units. Buyers typically order in batches of 2 to 10 units, with packaging in wooden crates lined with anti-corrosion film. Lead time is 15 to 25 days after payment confirmation. Payment is accepted via T/T or LC, and shipping is FOB Qingdao. The unit does not include mounting bolts or hydraulic hoses, which must be sourced separately.
