Ballscrews benefit from regular maintenance
When shipped, screws simply have a protective film. Before mounting or operating the ball screw, units must be lubricated with the proper lubricant (through the lube hole for nuts with wipers; directly onto the screw for nuts without wipers).

When using another lubricant, please verify compatibility with anticorrosion agent and eventually rinse unit prior to lubrication.
Caution: Do not use grease containing graphite or MoS.
