CAUTION
Always remove the grease nipple after replenishing the grease. Failure to do
so could cause damage if the grease nipple and robot interfere.
Method 1: Install the grease nipple onto the M6 tap hole on the ball screw
flange surface, and replenish grease using the grease gun.
Sufficient grease has been replenished when new grease starts to seep out to
the screw shaft.
Wipe off any excessive grease.
Recommended grease gun : MG70 (THK H-type nozzle)
Method 2: After wiping off the grease adhered on the rail and on the bearing
seal section with a rag, etc., apply a light coat of grease directly
onto the guide rail with a finger.
NOTE
Due to the structure of ZH, grease can be replenished only with this
method.
3) Return the stroke cover to the original position.
