Lubrication Methods - NTN-SNR LINEAR AXIS AXC Series Manual

Track roller guides
The hardened steel shafts and the rollers of the track roller guides are oil lubricated under normal conditions. The lubricating oils have
to correspondi to the specification ISO VG460. NTN-SNR usees as standard oil Shell Omala 460. Table 4.2 provides an overview of

Trapezoidal screw
For trapezoidal screws is the use of the same lubricants as for linear guides and ball screws is possible. Greases containing solid
additives (for example, graphite or MoS2) can be used in the series AXC, AXF and AXLT. The ingress of these lubricants into the
carriages is to be prevented.
Rack and pinion drive
The rack and pinion drive is optimally supplied with lubricant by a permanent lubrication system in combination with a felt rack-wheel.
The system is filled with the lubricant SNR LUB HEAVY DUTY. It can also be used for special versions with different lubricants.
