Unique Design of DUHUI Insert Bearings
The integrated, embedded design of DUHUI insert bearings allows for efficient and easy installation and removal.
The non-contact seal design of DUHUI insert bearings minimizes the risk of contamination and creates zero friction and wear.
The self-aligning design of DUHUI insert bearings automatically aligns, compensating for installation errors and shaft deformation, reducing the need for ongoing maintenance.


Surface Treatment of DUHUI Insert Bearings
During the processing of insert bearings, DUHUI will do targeted treatment on the bearing surface. We often use three types of treatment: shot peening, carburizing and surface coating.
Shot peening can improve the wear resistance and fatigue strength of Insert bearings, and also prepare for the next step of processing. Carburizing treatment can form a carburized layer on the bearing surface, which can effectively improve the bearing surface hardness and wear resistance, while maintaining the internal toughness of the insert bearing. Surface coating can effectively improve wear resistance and corrosion resistance.
More Competitive DUHUI Insert Bearings
DUHUI insert bearings are made of high-quality carbon core bearing steel and are manufactured in strict accordance with OE standards. Our insert bearings offer 5% to 20% greater durability than competing insert bearings, significantly extending their lifespan.
And our insert bearings feature a self-aligning function, reducing the need for regular adjustments. Our unique seal design also effectively reduces damage caused by external contamination. This significantly reduces ongoing maintenance costs.

The UC200 series is lightweight, while the UC300 series is heavy-duty.
Under light load and low speed conditions, the lifespan is generally between 50,000 and 100,000 hours.
Under high load and high speed conditions, the lifespan is significantly reduced, ranging from 10,000 to 30,000 hours.
You may need relubrication if your insert bearings are subjected to long-term, challenging operating conditions.
For example, high temperatures, high humidity, heavy loads, high speeds, and heavy loads.
