130903000088A002 Headrest Guide Sleeve Assembly Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

This product is a core safety accessory for the original equipment manufacturer (OEM) cab, compatible with various engineering machinery cab seats. Its core function is to provide precise guidance and stable locking for the headrest. Together with the headrest assembly, it enables fine-tuning of height and angle. When the vehicle is bumpy, it can fix the headrest and prevent displacement, ensuring the headrest’s protective function, reducing adjustment friction wear, improving smoothness, and is suitable for long-term operation in mines and construction sites. It extends the headrest’s service life, improves driving comfort and safety, and complies with relevant safety regulations and industry standards.
This product is precisely matched to the cab seats of Sany, XCMG, Caterpillar and other series of construction machinery. It is compatible with headrest assemblies such as model 130903000088A001. It adopts precision injection molding and polishing process, and is compatible with the original mounting holes and adjustment mechanism. It can be installed quickly without adjustment, withstands harsh working conditions, and is installed firmly without loosening. As the core component of the headrest adjustment system, it ensures the stable operation of the headrest assembly.

【Core Technical Parameters】

– Product Model: 130903000088A002
– Product Type: Headrest Guide Sleeve Assembly (Original Equipment Manufacturer, Headrest Guide Components for Construction Machinery Cabs)
– Compatible models: Cabs for Sany, XCMG, Caterpillar, and other series of construction machinery; compatible with loaders, excavators, bulldozers, etc.; compatible with headrest assemblies such as model 130903000088A001, which can directly replace original parts.
– Material: High-strength flame-retardant PC engineering plastic (reinforced nylon optional), precision injection molded and polished. PC material has a flame retardant rating of UL94-V0, tensile strength ≥400MPa, hardness ≥85D, is wear-resistant and odorless, and meets lightweight requirements.
– Operating temperature range: -30°C to +80°C (stable performance under extreme temperatures, no brittle cracking, aging or deformation, no degradation in guiding and locking performance, no jamming)
– Structural Specifications: One-piece guide sleeve with guide hole, locking groove, and anti-slip texture. It is compatible with a rack and pinion adjustment mechanism, ensuring precise guidance and secure locking. It can be used with a headrest to achieve 80-120mm height and 5-10° angle micro-adjustments. The built-in anti-slip structure prevents slippage and combines guiding, locking, and wear-resistant functions.
– Dimensions: Precisely fits the original headrest mounting holes and pins, with inner diameter and length conforming to the work station, matching the seat back and headrest assembly, with dimensional tolerances of IT7-IT8 grade, installation gap ≤0.15mm, and smooth guidance without jamming.
– Installation method: Clip-on + interference fit fixation, compatible with original factory hole positions. Clean the hole positions before installation, insert and tighten. No professional tools are required. After installation, it is stable and does not wobble, and does not affect the smoothness of adjustment.
– Protective properties: Waterproof, dustproof, and oil-resistant; surface is stain-resistant and easy to clean; salt spray resistance ≥480 hours; wear-resistant, aging-resistant, and UV-resistant; not easily faded or deformed; can withstand dusty and oily working conditions; prevents guide hole jamming.
– Service life: ≥4 years under normal working conditions, ≥2 years under harsh working conditions, no faults after 20,000 adjustment tests, no wear and deformation, stable locking, wear resistance ≥8,000 times, which can extend the service life of the headrest assembly.

Whether in bumpy environments, dusty mines, or extreme temperatures, this product consistently performs its guiding and locking function, ensuring headrest protection, reducing adjustment wear, enhancing driving safety and comfort, and lowering maintenance costs. It is an original factory compatible part with a unique code for traceability, perfectly matching the 130903000088A001 headrest assembly. It is a high-quality original part for headrest system repair and replacement, and for bulk stocking.
