taper roller bearing squeeze traditional markets through price competition

increase investment in the world bearing the giant forward China's low-end market expansion; while domestic companies manufacture products bearing 90% of the low-end products, squeeze traditional high speed bearings markets through price competition. Under the pressure of the squeeze,  urgent need to find a new market space.
Reduce the opportunity cost of the predicament in demand
Since the economic downturn, cost reduction became the needs of all businesses. Domestic enterprises to break through a host of foreign barriers, reduce costs and improve competitiveness, the demand for high-end products to replace imports increased significantly; equally to reduce costs, foreign companies and therefore increase the amount of purchases in China. To seize this opportunity,  to cultivate new growth points in the high-end bearings breakthrough, a breakthrough on the international market, the adjustment of product structure, the development of high-end products, to explore the international market and domestic high-end market.
In recent years, a large effort to develop fine, heavy, special, new products, high-end products to achieve High speed Spindle a breakthrough. Currently, railway wagon axle bearing  large and well-known companies in the bidding to the fore, began to supply; big bearing projects into production,  bearing products to further expand the range of processing; import substitution industrial gearbox bearings, mechanical bearings coal , precision motor bearings, wind power spindle bearings, bearing reducer orders substantial growth.
in critical manufacturing equipment has reached the world advanced level, to participate in international competition in the market has laid a solid foundation. In the first quarter of this year, put ZWZ bearings for industrial equipment orders have exceeded 2013 full-year orders.

for more oil wedge tilting ball bearing does not allow repair scratch pad

can be carved by hand scrape or bearing surface after turning padded repair scraping method adjustments.  2, cylindrical and oval on top of the bearing clearance , can be hand- scrape method or circumstances allow the bearing to the equatorial plane padded adjustments.  3, for more oil wedge fixed bearing, in principle, allow repair scratch and adjust bearing clearance , clearance inappropriate should be taper roller bearing replaced with new tile .  4, for more oil wedge tilting bearing, does not allow repair scratch pad , the gap should be replaced due to improper tile . Adjustable tile thickness can be adjusted by the amount of tile tile behind the next plus stainless steel pad adjustment block , block or adjust the thickness of the thinning method . Note for more oil wedge tilting high speed bearings  among the same group of tile thickness error should be less than 0.01mm.maintenance of technical requirements for the operation of the bearings to withstand load, speed , temperature , vibration, noise and lubrication condition monitoring and inspection , abnormal immediately find reasons to adjust to return to normal. Without further need for impact resistance as spherical roller thrust bearing materials using chrome steel , chrome molybdenum steel , nickel-chromium -molybdenum steel , the use of carbon infiltration quenching the steel from the surface to the proper depth of a hardened layer
