21.0 Greasing the Carriage
Use THK type AFB-LF grease. Do not substitute a different grease. There may be compatibility issues with dif-
ferent greases. Mixing incompatible grease types can damage the tool and cause premature failure of the linear
bearing system. The correct grease, and a grease gun for dispensing the correct 0.6cc volume, can be purchased
from:

IMPORTANT – Read This!
The AFB-LF grease can cause serious eye damage or irritation. Eye and face protection is
to be worn when performing the greasing service. THK provides an online MSDS for the grease at this URL:

The MSDS is to be reviewed before performing the
greasing service to the tool.
Figure 21: Greasing kit, THK part number MG70
The two items required to perform the greasing service are the THK MG70 Grease Gun and a 70 gram tube of
AFB-LF grease. The grease is included as a part of the MG70 kit.
The kit also contains several grease nozzles / adaptors. Use the “type L” fitting supplied with the kit (see figure
22 below). Grease is injected into the carriage by inserting the tip of the type L fitting into the open end of the
nipple on the end of the carriage, shown in the red circle in figure 20. Inject only the 0.6cc of grease that is dis-
pensed by a single pump from the grease gun. Grease injection is most effective after removing air from
the grease gun system. Apply moderate force to the back end of the grease cartridge using a blunt object such
as a dowel rod, while moving the grease gun lever through several cycles. The first several strokes of the grease
gun lever will cause a mix of air and grease to be ejected. Continue until there is very little or no air ejected with
the grease. Then insert the tip of the type L grease nozzle into the hole in the end of the fitting on the carriage.
Use a finger to apply force to the type L fitting to maintain engagement with the fitting on the carriage. Inject
just one stroke of grease. Application of excess grease can lead to internal problems with the carriage.
After injecting the new grease, wipe excess grease from the outside of the carriage, rail and grease nipple. Use
a clean soft cloth for cleanup of excess grease. A paper towel is not suitable for cleanup of grease. It is import-
ant to prevent the introduction of dirt and foreign debris into the linear bearing system, since that could cause
increased wear or damage and premature failure.
