Background

To keep the machine operating properly, and to extend the service life of the machine, you must verify that the linear rails and ball screws are properly lubricated.

Linear Rails

The linear bearing blocks are sealed and lubricated during machine assembly, which makes them relatively low maintenance components. The recommended service interval (from the linear bearing manufacturer) is between 500-1000 km, depending on load rating. We recommend lubricating the linear bearing blocks every 6 months, which assumes that you're using the machine at its maximum velocity for 8 hours every day, and that the lubrication interval is every 500 km.

• Recommended Lubrication Quantity 0.3 cm3 grease per block

  • You must only use the amount of lubrication and at the pressure specified in this section. If you use excessively high quantities of lubricant, or excessively high lubricating pressure, it could cause machine damage.

• Maximum Lubricating Pressure 30 bar

• Recommended Grease Type Hiwin G05 General Type Grease (or greases that are in accordance with DIN 51825 of consistency class NLGI No. 2 as specified by DIN 51818)

  • Don’t use greases with solid particles, like graphite or MoS2

To lubricate the rails:

1. Identify the machine’s bearing blocks.

   Open

   

2. Identify the lubrication port on the bearing blocks.

   Open

   

3. Find the Grease Gun (PN 50360) and the Grease Nozzle Kit (PN 50389) provided with the machine. From the Grease Nozzle kit, identify the concave nozzle.

4. Assemble the Grease Gun with the concave nozzle, and lubricate the linear bearings with the recommended lubrication quantity once every 6 months.

Ball Screws

The recommended lubrication interval (from the ball screw manufacturer) is every 2-3 months or 100 km of travel. We recommend lubricating the ball screws every 2-3 months, which assumes that you’re using the machine at its maximum velocity for 8 hours every day.

• Maximum Lubricating Pressure 30 bar

• Recommended Lubrication Quantity 0.3 cm3 grease per block

  • You must only use the amount of lubrication and at the pressure specified in this section. If you use excessively high quantities of lubricant, or excessively high lubricating pressure, it could cause machine damage.

• Recommended Grease Type Hiwin G05 General Type Grease (or greases that are in accordance with DIN 51825 of consistency class NLGI No. 2 as specified by DIN 51818)

  • Don’t use greases with solid particles, like graphite or MoS2

1. Identify the three remote-mounted lubrication ports.

2. Use the Grease Gun (PN 50360) provided with the machine (and its attachments) to lubricate the ball screws with the recommended lubrication quantity once every 2-3 months.
