Product Description
Ensure the long-term reliability of your Yutong bus’s axle and
wheel hub assemblies with the 220307A Oil Seal Seat, a critical component manufactured by Nanjing Dingguan Auto Parts Co., Ltd.
This isn’t just a simple metal ring; it is a high-precision housing
engineered to securely hold the oil seal in place. Its primary
function is to maintain the integrity of the sealing system, which
is vital for preventing lubricant leakage and protecting sensitive
bearings from contamination by dust, water, and road debris.
Crafted from high-strength, durable materials and machined to exact
OEM specifications, our 220307A Oil Seal Seat guarantees a perfect
fit and optimal performance. The precise dimensions ensure that the
oil seal is perfectly aligned and seated, creating a robust,
leak-proof barrier. This precision is key to preventing premature
bearing failure, which can lead to costly repairs and significant
vehicle downtime.
As a direct replacement part for Yutong buses, installation is
straightforward and reliable. By choosing this quality component
from Nanjing Dingguan, you are making a smart investment in
preventative maintenance. Protect your major driveline components,
extend their service life, and enhance the overall safety and
efficiency of your fleet.
