Import Bobcat Cylinder Arm 7175158 — Buy in wholesale FOB from Supplier in China

The Bobcat Cylinder ARM 7175158 is a hydraulic arm cylinder built for Bobcat compact equipment, manufactured by A&S Construction Machinery Co., Ltd. in Chengdu, Sichuan, China. This part serves as an OEM replacement for damaged or worn arm cylinders on designated Bobcat loader and excavator models, converting hydraulic pressure into the linear force required to raise and lower the loader arm or dipper mechanism. A&S Construction Machinery produces this cylinder to match the original mounting geometry, port configuration and pin bore dimensions of the 7175158 reference number, ensuring direct interchangeability without modification to the host machine.

The cylinder body is typically constructed from seamless honed steel tubing with a standard chrome-plated piston rod to resist corrosion and scoring in abrasive construction environments. Sealing systems generally consist of a polytetrafluoroethylene (PTFE) rod seal, a polyurethane wiper and a nitrile backup ring, though the exact compound specification should be confirmed with the supplier. Bore diameter, rod diameter and overall retracted length align with the 7175158 OEM envelope, with standard pressure ratings typical for compact loader arm circuits in the 2,000 to 3,000 psi range. Surface finish on the bore is typically 0.2 to 0.4 micrometres Ra to maintain seal integrity and minimise friction losses.

This replacement cylinder suits fleet operators, independent rental yards and refurbishment workshops maintaining Bobcat compact track loaders or mini excavators. Buyers should verify compatibility with their specific machine serial number before ordering, as Bobcat has used multiple cylinder revisions across model years. A&S Construction Machinery also supplies complementary hydraulic components including seals, couplers and hydraulic valves from the same Chengdu facility. The supplier lists an address at 469 Xinsheng Road in Wuhou District, with no response rate data currently available, so direct enquiry is recommended to confirm current stock, exact dimensional drawings and any available core-exchange or warranty terms.

A&S Construction Machinery Co., Ltd. is headquartered at 469 Xinsheng Road, Wuhou District, Chengdu, Sichuan, China 610041, operating from the organic supplier tier with a harbor trust designation. The company maintains a broad replacement parts catalogue spanning hydraulic cylinders for over fifteen construction equipment brands including Caterpillar, Komatsu, John Deere, Sany, XCMG, Volvo, Hitachi, Sumitomo, Liebherr, Doosan, Case, Bobcat, Kubota, Yanmar, Hyundai and Daewoo. Beyond cylinders, the supplier lists additional component lines including cylinder liners, crankshafts, oil pumps, solenoid valves, fuel injectors, batteries, radiators, compressors, gaskets, turbochargers, hydraulic pumps and motors, bearings, gears, drive shafts, brakes, alternators, controllers, sensors, filters and undercarriage elements. The supplier profile does not indicate verification by third-party audit, nor does it publish response statistics, so buyers should conduct independent due diligence.

The listing presents A&S Construction Machinery as a parts trading and manufacturing operation rather than an exclusive OEM supplier, which is common in the Chengdu machinery corridor. No information is provided about factory size, workforce, annual turnover, specific quality certifications or named client references. The harbor trust tier suggests basic profile completion without advanced verification. Buyers should request dimensional inspection reports, material certificates and pressure test documentation for any cylinder order, and clarify whether production is in-house at the Chengdu address or sourced through subcontract arrangements. Direct communication through the provided contact channel is essential to establish lead times, minimum order quantities and any export documentation support.
