KYB Motor MSF-53 20460-35303 MSF-46 20460-35303 MSF-41 MSF-23 MSF-12 MSF-42 Hydraulic Pitston Motor

MSF-53 is a specification part number in the KYB hydraulic rotary motor series, specifically referring to radial piston hydraulic motors with a displacement of approximately 53cc, mainly used in small excavator rotary systems. ‌‌

Core Features
Structural type: Radial plunger design, strong impact resistance, suitable for frequent start stop and heavy-duty rotation conditions;
The series has a complete range of models: MSF-41/MSF-23/MSF-12/MSF-46/MSF-50 MSF-53 20460-35303; MSF-52,MSF-49,MSF-48,MSF-40,MSF-10，MSF-11;
Typical application: matching the rotary drive system of 6-8 ton small excavators (such as models from Shengang, Kato, Sumitomo, etc.);
Performance positioning: Medium torque output, balancing response speed and durability, often used as original factory accessories or replacement parts for maintenance;
Compatibility: It can share some accessories (such as oil distribution plate, plunger, cylinder body) with MSF46, MSF65 and other similar series components, but the spindle and seal need to be matched according to specific models;
Maintenance feature: Modular maintenance design, supporting separate replacement of worn parts (such as return discs and transmission shafts), reducing the overall lifecycle cost. ‌‌
