Hydraulic Parts OVERVIEW

SG02, SG025, SG04, SG08, SG12 and SG20 hydraulic spare‑parts are high‑quality aftermarket replacement components for TOSHIBA MFB‑series swing piston motor, covering MFB40, MFB80, MFB160 and MFB250 rotary motor assemblies, widely equipped on various‑tonnage excavators. This product series includes core wearable parts: cylinder block, valve plate, piston shoe, retainer plate, ball guide, drive shaft, bearing and complete seal overhaul kits. Manufactured with high‑strength wear‑resistant alloy and ultra‑precision machining, these spare‑parts fully match original motor specifications, effectively solving common swing‑motor failures such as slow rotation, insufficient rotary torque, abnormal noise and hydraulic‑oil leakage.

Features and Benefits

  • Excellent Interchangeability: Strictly produced according to TOSHIBA SG‑series original standards, directly replacing original swing‑motor spare‑parts with no extra modification required.

  • Superior Wear‑resistance: Premium alloy raw‑material reduces friction loss under long‑time heavy‑load and high‑pressure operation, greatly extending swing‑motor service‑life.

  • Stable Rotary‑Performance: High‑precision grinding and strict dimensional‑tolerance control ensure smooth slewing movement, low‑noise running and steady torque‑output under continuous‑working conditions.

  • Flexible Selection: Separate single loose‑parts and complete overhaul repair‑kits are available, to satisfy different maintenance‑and‑rebuilding demands.

  • Reliable Quality‑Control: Every batch of spare‑parts passes full‑performance inspection before shipment, delivering stable performance and low‑failure‑rate in tough construction‑site conditions

Applications

  • Ideal hydraulic spare‑parts for maintenance, overhaul and refurbishment of TOSHIBA SG02/SG025(MFB40), SG04(MFB80), SG08(MFB160), SG12, SG20(MFB250) swing motors installed on different‑size excavators. Widely used in earth‑moving, municipal‑engineering, road‑construction and other engineering‑projects, perfectly suited for hydraulic repair‑shops and machinery‑maintenance workshops.
