Support seat Description: the ball screw rod support seat is the bearing connecting the wire rod and the motor. The structure and the special length to the standard ball screw stock axle end finished product, prepared the standard support unit EK, EF type, the standard support unit BK, BF type to the general ball screw screw.
The supporting unit on the fixed side is equipped with preload adjusted JIS5 angular contact ball bearings.
Especially in the super miniature EK6 and 8, the super small angle contact ball bearing with 45 degree contact angle developed for the super small ball screw can obtain high rigidity and high precision and stable rotary performance.
The support unit on the support side uses a deep groove ball bearing.
The internal bearing of support unit EK and BK is loaded with a suitable amount of lithium soap grease, sealed by special sealing washer, which can be directly installed and used for a long time.
(1) the use of the best bearings takes into account the balance of the ball screw on the rigidity and the use of high rigid and low torque angular contact ball bearings (contact angle 30 degrees, free combination). At the same time, the mini support units EK6 and 8 are equipped with ultra small angular contact ball bearings developed for miniature ball screws. The contact angle of the bearing is 45 degrees, the ball is small and the number of balls is more. It is a super small angular contact ball bearing with high rigidity and high precision. It can obtain stable rotary performance.
(2) the supporting unit of the supporting unit has a series of corners and circles, and can be selected according to the use.
(3) small and easy installation supporting unit is designed with small volume installed around the space. At the same time, the bearing which has been loaded through the adjustment preloading can be assembled directly after delivery, which not only reduces the assembly time, but also improves the type of the ball screw support seat of the type of assembly precision.

The support seat has 8 models. The standard support seat EK, EF, FK, and FF are prepared for the axle end and finished product of the standard ball screw screw stock. The standard support seats are prepared by the standard support seats AK, AF, BK and BF.
The fixed side is equipped with pre adjusted JIS5 or P0 grade angular contact ball bearings, which can be selected according to the screw grade. High precision and stable rotary performance.
The support side uses deep groove ball bearings. The support bearing EK, BK, FK and AK bearing contain proper lithium soap grease, with special seal. (1) install the fixed side to the screw. (2) insert the fixed side, tighten the locking nut, and fix it with pad and inner six angle bolt. (3) the support side bearing is fixed on the screw shaft with the stop ring and loaded into the support side support seat.
Note 1: do not disassemble the support unit.
Note 2: when the screw shaft is inserted into the support unit, be careful not to turn the flange of the oil seal gasket.
Note 3: when the inner six corner bolts are used to compress the pad, to prevent loosening, tighten the six angle bolts when they are coated with adhesive.
