Loader Gearbox Seals

Provide customized loader transmission seals made of NBR/FKM material with high temperature and high-pressure resistance and designed for Caterpillar, Komatsu, and other brands. Support OEM service, ISO certification, and fast delivery worldwide.

Why are loader transmission seals critical?

The gearbox is the core component of loader power transmission, and its sealing performance directly affects the operating efficiency and life of the equipment. Poor quality seals can lead to oil leakage, dust ingress, gear wear, overheating, and even transmission failure. Our rubber seals are designed for severe service conditions to ensure leakproof, abrasion resistance, long life, and reduced equipment maintenance costs.

Product Benefits: Tailor-made for heavy machinery

Excellent material

High temperature and high-pressure resistance: imported nitrile rubber (NBR) or fluorine rubber (FKM) is used to withstand extreme temperatures from -40 °C to 200 °C, and adapt to the high-load gearbox environment.

Anti-aging and anti-corrosion: special formula enhances anti-ozone and anti-hydraulic oil corrosion performance, and prolongs the service life of seals.

Precision process

CNC mold forming technology to ensure dimensional accuracy (±0.05mm), perfect fit the gearbox housing, and eliminate leakage.

The multi-layer reinforced structure design improves the compression resistance and resilience to avoid seal failure caused by vibration.

Wide compatibility

Compatible with Caterpillar 950G, Komatsu WA380, Volvo L150, and other mainstream loader models, support customized by drawings or samples (OEM/ODM).

Application scenarios and customer pain points are solved

Mines & Construction Sites: Dust-proof design blocks the ingress of gravel particles and protects the inside of the gearbox.

High temperature and high humidity environment: Fluoroelastomer material can cope with moisture and chemical corrosion to ensure sealing stability.

Long-term high-load operation: reduce the frequency of downtime and replacement, and improve equipment uptime.
