Ball screw support base is connected to the screw and motor bearing manufacturers, construction and specialty bars for standard ball screw shaft end finished goods inventory, prepare a standardized support unit EK, EF type, the general preparation of the ball screw bars standard support unit BK, BF type. The fixed side support unit fitted with JIS5 level preload adjusting the angular contact ball bearings. Especially in EK6,8 ultra-compact formula, equipped with ultra-small angle bars for ultra-small ball screw developed by the contact angle of 45 ° contact ball bearings, to achieve high rigidity, high precision and stable rotation performance. Support side support unit using deep groove ball taper roller bearing. Support unit EK, BK type of internal load bearing right amount of lithium soap grease, sealed with a special gasket, can directly install, long-term use.
Precision bearings according to ISO grading standards are divided into: P0, P6, P5, P4, P2. Rank higher in turn, where P0 is the general accuracy, other grades are precision level. Of course, different classification standards, different types of bearings, their classification method somewhat different, but the meaning is to the. The use of performance requirements of precision bearings rotating body with high runout accuracy, high-speed rotation and small changes in friction and friction.
