Installation Note:
1. If the steel ball cannot be lost, the nut is mounted on the screw, but the lack of steel ball will greatly reduce the life of the screw. (80% of the steel ball ensures normal positioning and operation of lead screws.)
2. When installing the inner ring screw, be careful not to mount the steel ball in the non-slide tank between the two circulators (this part of the grooves at both ends seal, the length is about a quarter) one cycle path length. ), It will bite the screw, the cycle is not smooth, the gap it produces, which is not smooth.
3. When placing the steel ball into the spiral groove, please pay attention to the unfilled all cyclic channels. According to the principle of the ring, the nut is four inverters, namely 4 rings. When the steel ball is placed in each cycle ring, there will be small space (approximately 314 steel ball diameter distance) to facilitate the rolling and cycle of steel balls in the circulation passage.
