DFU3205 Ball Screw

Description

Ball screw--DFU3205 ball screw is one of the common mechanical parts. Its main feature is to convert the rotary motion of the motor into linear motion. Generally speaking, the length of the ball screw-DFU3205 ball screw is large than the stroke required for movement, so that the ball screw can reciprocate within the safe stroke.

1. The ball screw - DFU3205 ball screw want to be kept clean and blanketed with anti-rust oil. Special interest ought to be paid not to permit sharp objects or tools to hit the tooth surface and not to allow any iron filings to enter the inside of the nut; and when assembling the shaft The outer diameter of the give up must not be damaged by collision or scratches.

2. Select a ball screw with a appropriate accuracy stage and set up it in accordance to the standard assembly procedures.

3. To make the ball screw reach the maximum service life, DFU3205 ball screw grease should be stored crammed on the metallic balls and ball grooves. Either the oil bath type or the dripping type oiling method can be used, however direct oiling into the nut is better.

4. Pay special attention when putting in the ball screw - DFU3205 ball screw on the machine. Do not knock the nut or bent pipe. At the same time, do not allow the nut to separate from the screw or over-travel - part of the nut's stroke leaves the screw. If so, it will Cause the metal ball to get away from the ball groove.

5. Choose a appropriate shaft end support bearing combination. On CNC laptop tools, it is endorsed to use bevel bearings (bevel angle: 60°).

Product Details

DFU ball screw are higher than SFU in load capability and rigidity for the nut is longer and inside balls quantity is more. The set up dimensions of single nut and double nut are the same except for the length (double nut length is twice that of single nut). At the same time the load is greater than two instances the single nut. Double nut mainly used for relatively large equipment transmission.
