Processing advantages

1. high-quality steel, long service life.

CHAENG bearing pedestal uses high-quality SCW480 steel, with high hardness, strong wear resistance, high load-bearing, long continuous work, good stability, and long service life.

2. low operating temperature, energy saving effect

CHAENG bearing pedestal takes use of thin oil lubricant to minimize the friction coefficient of bearings. So the energy-saving effect is good, the working temperature is much lower than the dry oil and extend the bearing service life.

3. Set the oil level observation scale, reduce maintenance costs

CHAENG bearing pedestal sets the oil level observation scale, which make the staff be able to observe the oil level situation, timely replenish oil, to prevent accident damage caused by lack of oil lubrication.

4. reasonable structure, environmental protection

Through removing one outer sleeve of the bearing, the bearing pedestal can prevent dust into the bearing box to maintain good oil lubrication, so as to ensure bearing life and energy saving.

Wood pattern - Sand Molding - Pour - Out of Pit, Clear Sand - Heat Treatment, Finishing - Roughing, Finish Machining - Flaw Detection - Packaging, Shipping

Bearings pedestal require a higher strength and wear resistance, and requires a certain shock absorption performance, because the bearing pedestal in the entire ball mill operation is the main support pieces. Therefore, in the casting of the bearing seat, from the choice of materials to heat treatment, each step is a complex and very strict manufacturing processes.


CHAENG bearing housings are widely used in ball mill, coal mill and rolling mill.

One typical example: A Japanese company signed an agreement with CHAENG requiring material with SCW480 type steel, for its specialized production of bearing base. CHAENG showed their manufacturing strength, all bearing pedestals fully meet the requirements of the Japanese companies. CHAENG not only made a profit, but also expand company's overseas market and win a good reputation.
