Bearing System
The ServoTube modules are supplied as complete, ready to use mechanical systems. Each system incorporates a
prole rail re-circulating ball bearing system for support and guidance. The bearing carriages, to which the moving
forcer is attached, are fully charged with grease before delivery. During the life of the system, this grease will need
to be replenished. The interval for replenishment will vary depending on the parameters of operation. Systems
carrying heavy payloads and travelling at high speeds with fast acceleration and deceleration will need re-greasing
more often than systems carrying light payloads and travelling at slower speeds. However, as a general guide,
re-greasing is recommended at intervals of 1000 km.
In order to re-grease the bearing carriages effectively and with minimum spillage, a delivery tube with a specially
designed nozzle to engage with the lubrication nipples on the bearing carriages is required. These are available
from your supplier complete with a fully charged, small (70 g) side lever grease gun.

CAUTION. Different types of grease should never be mixed as they can cause damage to the
bearing rail due to their incompatibility. The bearing system must only be lubricated via the
bearing carriages. Do not lubricate the bearing rail. Do not lubricate the thrust rod, it is not a
bearing surface.
