ZYS series cage: angular contact ball guide plastic cage, roller screw plastic cage bearings

ZYS series cage: angular contact ball guide plastic cage, roller screw bearing plastic cage - 2021 02 - 19 ZYS® Angular contact ball guide plastic cage ZYS® Angular contact ball guide plastic cage areas of application: precision CNC lathe spindle machining center spindle bearing and bearing grinder spindle bearings, etc. ZYS® Angular contact ball guide the basic parameters: the plastic cage ZYS® Ball screw bearing ZYS® plastic cage and materials; Plastic roller screw bearing retainer materials: high quality PA66 - GF25 aggregate. ZYS® Plastic roller screw bearing retainer materials properties: heat resistance - 40 ~ + 120 ℃, fatigue strength and high rigidity, good heat resistance, low friction coefficient, good wear resistance. ZYS® Plastic roller screw bearing cage areas of application: precision ball screw bearing. ZYS® Plastic roller screw bearing cage basic parameters: the development trend of bearing cage: because of the difficulty maintains a special processing method or technology limitations, and considering the force, lubrication, the speed, temperature and so on various aspects factor and the influence of the market for bearing high speed, high precision, overload, long life and low noise, continuous improvement and development of bearing cage technology has become inevitable. Cage structure improvement and development should have the following characteristics: (1) on the basis of the guarantee strength, can make the rolling element bearing will be increased in quantity or geometry size, in order to improve the bearing capacity and service life. (2) have the ability to improve the self-lubricating bearings, can reduce the noise at the same time, meet the requirements of bearing increase speed and reduce noise. (3) have save raw materials and reduce the impact on the surrounding environment, improve material utilization and save raw material is the trend of The Times, especially with the limited resources of material rising tensions, with steel and copper, with plastic instead that structure improvement and replacement of cage plays a promoting role. (4) improve the surface hardness and lubricating ability of cage will become the development direction of new structure cage. Blasting, finishing, blue and other physical and chemical processing, to reduce the maintain internal stress, improve the surface roughness and the lubricating ability has played a positive role. Some structures such as short conical, cylindrical and spherical roller bearing, needle roller bearing cage surface nitriding or soft nitriding treatment are to improve the mechanical strength and wear resistance of cage, prolonging the life of the cage play a key role. Cage in bearing belongs to the weak parts, improve the machining accuracy and life of the cage for the direction of the continuous efforts. With rapid development of increasingly bearing requirements, the need to constantly communication, continuous improvement of the defects in the cage at present, promote the development of the cage and innovative thinking, to develop more suitable for all kinds of bearing cage. （ Source: shaft research institute)
