60313915 Left Seat Rail Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 60313915 left seat guide rail is a core seat guide component customized by the original manufacturer for the cab. It is specially designed for various engineering machinery cabs and is used for sliding guidance, load-bearing support, and locking limit on the left side of the seat. It features smooth sliding, stable load-bearing, impact resistance, vibration reduction, and anti-shaking functions, ensuring that the driver and passengers can smoothly adjust the seat’s fore-and-aft position. It is suitable for bumpy operations in mines and construction sites, preventing the seat from sliding, jamming, shifting, or loosening. It provides precise guidance for seat adjustment, improving driving comfort and operational safety.
This product is an original equipment manufacturer (OEM) accessory, precisely matched to the cab seats of SANY, XCMG, Caterpillar and other series of construction machinery. Utilizing CNC machining, precision stamping and ball bearing inlay technology, it is compatible with the original seat installation position and seat sliding mechanism, allowing for quick installation without complicated adjustments. It can withstand bumpy, high and low temperature and dusty and oily working conditions, with smooth sliding and firm locking. It complies with GB/T 1184-2008 and QC/T 831-2010 standards and follows EN ISO 5010:2019 and GB 15083-2019 safety standards.

【Core Technical Parameters】

-Product Model: 60313915
– Product Type: Left Seat Guide Rail (Original Equipment Manufacturer, Special Sliding Guide and Load-Bearing Accessory for Construction Machinery Cab Seats)
– Product Brand: Genuine Original Product (Compatible with various construction machinery cabs, of the same quality, and with guaranteed after-sales service)
– Compatible Models: Cabs of Sany, XCMG, Caterpillar, and other construction machinery; precisely matched with seat sliding mechanisms; suitable for left-side mounting on loaders, excavators, and other construction machinery.
-Material: High-strength cold-rolled steel sheet (SPFC980 or DP1180 optional), CNC machined, precision stamped, ball-bearing inlaid, with zinc-nickel alloy coating on the surface. Tensile strength ≥520MPa, hardness HRC28-32, capable of withstanding vertical loads ≥4000N.
-Operating temperature range: -30°C to +80°C (Structural stability under extreme temperatures, smooth sliding, no degradation in locking performance, no brittleness, no aging, and no grease dripping)
– Structural Specifications: Integrated guide rail structure, including guide rail body, ball bearing assembly, locking mechanism, and dust cover. It features a four-row arc groove design with a 45° contact angle, combining sliding guidance, load-bearing support, locking limit, and dust protection functions. It allows for smooth forward and backward sliding of the seat, has strong self-aligning capability, and can absorb minor deviations in the mounting surface.
– Dimensions: Precisely fits the original factory seat installation position; the guide rail length, width, and thickness perfectly match the installation requirements, seamlessly integrating with the seat sliding mechanism and the cab mounting surface. Dimensional tolerances are IT7-IT8 grade, with front-to-back clearance ≤0.35mm and left-to-right/up-to-down clearance ≤0.50mm, conforming to QC/T 831-2010 requirements.
-Installation method: Bolt fixing, compatible with original factory mounting holes. Before installation, remove burrs and dirt from the mounting surface and apply low-viscosity lubricant. Installation is convenient and allows for quick replacement. A torque wrench is required to tighten to the specified torque. After installation, ensure smooth sliding without loosening or misalignment.
– Protective Performance: Waterproof, dustproof, and oil-resistant; surface treated with zinc-nickel alloy plating; salt spray resistance ≥500 hours; wear-resistant, aging-resistant, and UV-resistant; does not easily fade or deform; strong plating adhesion with no peeling or blistering; dust cover effectively prevents dust and debris from entering the guide rail.
-Service life: ≥4 years under normal working conditions, ≥2 years under harsh working conditions; after 8000 working cycles (including 1500 cycles at extreme positions), there is no deformation or jamming; the sliding resistance decreases by no more than 25% of the initial value; it can withstand 15 impacts of a 147m/s² half-sine wave without significant deformation.

Whether in bumpy environments, dusty mines, or extreme temperatures, this product consistently performs its functions of guiding the seat’s sliding motion and locking the load, ensuring smooth and stable fore-and-aft adjustment, secure positioning, reduced seat shifting and wobbling, improved driving comfort and operational safety, and lower maintenance costs. Original factory compatible, with a unique code for traceability, it is a high-quality genuine part for repairing and replacing the left guide rail of a construction machinery cab seat, and for bulk stocking.
