Hyundai R55W-9 Excavator HUB SEAL KIT Wheel Hub Repair Kit Medium-Sized Models

The main difference between the R55W-9 and the DX140W is that it is designed for smaller "tool bag" style wheel ends.

Operating Temperature

Due to high-quality sealing materials (especially fluororubber), its typical operating temperature range is approximately

-40°C to +180°C.

It can adapt to a variety of operating conditions, from cold winters to continuous braking generating heat, with stable performance.

Features

**Specifically Sized: Designed for medium-sized machines, smaller than heavy-duty kits like the DX140W.

**Long-Lasting Protection: Combining magnetic adhesion and high-quality sealing materials, its design life far exceeds that

of ordinary O-rings or simple oil seals.

**Preventative Maintenance: Ideal for regular maintenance and preventing breakdowns en route.

**Easy Installation: As a complete kit, it provides all the parts needed for single-wheel-end maintenance, simplifying the repair process and inventory management.

**High Cost-Effectiveness: For medium-sized fleets, it effectively reduces downtime costs and repair expenses due to wheel-end failures.

Pressure Withstandable: The wheel hub sealing system is not a high-pressure system. The R55W-9 primarily withstands:

Static pressure of the grease: very low.

Thermal expansion pressure: the pressure generated by the expansion of grease and air due to temperature changes at

the wheel end during operation; the design incorporates a margin of safety.

The main challenges are dynamic sealing (rotating shaft) and preventing the intrusion of external contaminants, rather than withstanding extremely high internal pressures.

Our company regularly participates in well-known domestic and international construction machinery exhibitions

(Bauma China, Russia, Indonesia, Iran), and has established good cooperative relationships with international partners.

We look forward to the opportunity to meet you in the future.
