ZZ’s regular service includes installation & maintenance, technical support and consulty and after-sale service. 


Besides offering normal standard bearings to the customers, ZZ also focus on research and development for bearings applied in special fields. In recent years, ZZ designed and optimized the bearings for mining and paper making industries. Those special designed bearings not only help the customers realize the goal of reduction on cost, but also increased the equipment’s sustainability. 


A.The special products for Mining equipment manufactured by ZZ are as follows: 


Spherical roller bearings with different cage design as MBA (machined brass cage,inner ring centred), MA(machined brass cage,outer ring centred), and CCJA(stamped steel cage,outer ring centred) produced by ZZ are able to meet the strict and harsh demanding in vibrating screen.Those bearings have passed continuous testing and are optimized on internal parameters. Meanwhile with improvement on techniques, the average operating temperature of those bearings are decreased 10℃ which meet the longer service life requirements from the vibrating screen customers. 


China cylindrical roller bearings,with the cage design as ECML (machined single brass cage, outer ring centred) and ECM (machined single brass cage, roller centred) produced by ZZ are able to meet the strict and harsh demanding in vibrating screen and sand maker, like lower temperature increasing level, lower noise level and longer service life. 


B.Large spherical roller bearings used in all kinds of pressing equipment of paper making industry manufactured by ZZ are as follows:


Modern paper making equipment with the feature of high speed, high output and high reliability set very strict requirements to the bearings applied on the aspects of high precision, high speed, high reliability and longer service life.


Owing to its continuous pursuit on the best design and techniques , the big-sized spherical roller bearings applied in the key equipment of paper making machine which are produced by ZZ have met the customers’ demand and also won high reputation in paper making industry home and abroad.
