Environmental temperatures of more than 60 °C/ 140 °F can harden the used lubricants faster.
Therefore, lubrication and maintenance works have to be carried out more often.
7.2 Notes
Please observe the following notes to ensure correct functioning of the rotary actuator:
1. Standard for quality of the compressed air according to ISO 8573-1:
6 4 4
2. Wearing parts can be ordered from SCHUNK. The order number and the contents of the
seal sets can be found in chapter 9.
3. During maintenance, grease the serration with SCHUNK LINO MAX (order no.
0184211), and grease all the other friction surfaces and seals with Renolit HLT 2 or a
comparable lubricant.
4. Unless otherwise specified, secure all screws and nuts with Loctite no. 243.
