Assembly Instructions
Linear Axes HM-S and HT-S
HMS_HTS-01-0-EN-1905-MA
7.1.1 HM-S linear axis lubrication
The HM-S linear axis includes a linear guideway with two blocks and a ballscrew that are initially lubricated prior to delivery.
Relubrication is introduced through three grease nipples each on both sides of the carriage. The outer grease nipples are
used to lubricate the blocks, the middle one the ballscrew.

The relubrication intervals can possibly be shortened under the following conditions. In such cases, please consult HIWIN:
v > 3 m/s, a > 30 m/s 2 , contact with media, temperatures < 20 °C or > 30 °C, soiled ambient conditions.
