40+ YEARS EXPERIENCE\u00a0<\/u>
CONTINUOUS AND STABLE DELIVERY OF PRODUCTS.<\/b> <\/p>\n

With over 40 years experience of the bearing manufacturing, we know how to make good bearings with less cost consistently and efficiently.<\/p>\n

We use advanced CNC turning, grinding, and superfinishing machines to ensure high, stable, and accurate machining.\u00a0 All of your goods, from the most economical category, to the highest rated category,\u00a0will always be manufactured precisely to the standards you require.<\/p>\n

OWN HEAT TREATMENT\u00a0<\/u><\/b>
CONTROALLABLE COST AND QUALITY.<\/b><\/p>\n

Heat treatment is 1 of the crucial processes to ensure high performance of bearing materials.\u00a0Compared with other manufacturers, we can produce higher quality bearings at smaller cost<\/b>, with a more flexible and controllable production schedule<\/b>, and in a shorter time<\/b>.\u00a0<\/p>\n

\n

\n

\n

\n

We have 6 heat treatment production lines.<\/p>\n

Bearings are heated uniformly, with small deformation and little\/no oxidized decarburization, which can make them have high hardness, high fatigue resistance, good wear resistance, dimensional stability, and excellent mechanical strength.<\/p>\n

OUTSTXIHU (WEST LAKE) DIS.\u00a0 QUALITY<\/u>
LOW NOISE, LOW FRICTION AND LONG LIFE.<\/p>\n

All our products are characterized by low noise, low friction and long life<\/b>.\u00a0 This is due to our attention to the roundness, waviness and surface roughness of bearing raceway.<\/p>\n

Our products fully meets the requirements of national and international standards accorind to the testing result of
roughness, roundness, hardness, vibration noise, vibration velocity.
