BeiJing ZhongXing ShiQiang Engineering Ceramic Co.Ltd(SQ)
BeiJing ZhongXing ShiQiang Engineering Ceramic Co.Ltd, is a high-tech ceramic special co***ny in BEIJING.
The main products of co***ny, zirconia,Aluminum oxide,silicon carbide,silicon nitride bear-ings,balls, and a great many workpieces of the mentions ceramic. The bearings have obtai-ned the CHINESE STATE NEW PRODUCT,in 2002 , and seven patents assigned by China Patent office, SQ produces ceramic bearings,balls and other products in quantities to meet the requirement of domestic and foreign customers. the ball¡¯s size is fro-m 0.5 to 90mm and precision includes G5-G100, All qualitles are certified by national bearing compo-nents certified center. Full ceramic ball bearings (outer ring ,inner ring and ball are madeof ceramics,cage is made of Teflon or graphite reinforcing )and hybrid ceramic ball beari-ngs (outer ring and inner ring are made of steel) made by SQ and its cooperative units have been exported to USA¡¢GERMANY¡¢JAPAN¡¢TAIWAN AND KOREA customer andother countries and areas. The SQ products of ceramic and ceramic bearings have been successfully applied in aviation and aero***ce spheres,contributing to a lot fornational defe-nse. Today ceramic bearings of various specification in a wide rang of sizes,which are made by SQ,have been assembled in precision, high speed main shaft dental drill instru-ment bearing, computer hard disk driver and electric fan, anti-magnetic, anti-corrosion,high-temperature,applications.
Field of Application
Ò»£©High temperature field
The transmit roller of high temperature furnaces:Si3N4 ceramic retains strength and harden-ss nearly up to 800¡æ,and Aluminum oxide ¡¢silicon carbide nearly up to 1000--1400¡æ,but bearing steel hardness drops above 120¡æ
¶þ£©High-speed rotation field
Such as high speed motor spindle bearings,main shaft bearings of machine.The specific gra-vity of Si3N4 is 3.20g/cm and that of bearing steel is 7.85g/cm,We can see the former ismuch lower than the latter,therefor the ceramic rolling ele
