MQ-150 Ballscrew Feed Unit
Lubrication Instructions
The MQ-150 unit bearings are lubricated with synthetic lubricant. Kluber Isoflex
NBU-15 is used on all rolling bearings (ball bearings and ball screw).
Kluberpaste 46 MR 401 is used on the sliding surface of the spline shaft. The quill
is lubricated with standard petroleum based grease. Do not mix petroleum
lubricants with the synthetic lubricants used on the spline shaft, ball screw and
bearing.. This will cause breakdown of the synthetic lubricant and could result in
premature failure of critical components.
Lubrication should only be required when service is done to the unit, components
are replaced or the lubrication should dissipate from the lubricated component or
surface for any other reason. The bearing lubrication is sometimes referred to as
“permanent” in that it should last the life of that particular component unless
subjected to abnormal use or exposure. Due to extreme load and speed
conditions, it is highly advisable that the lubricated components should be
checked at regular preventative maintenance intervals. Many coolants and cutting
fluids are destructive to the lubrication, particularly the quill lubrication so it may
be necessary to inspect and re-lubricate this component more frequently.
The benefit gained by the use of this type of grease lubrication is that it allows the
unit to be mounted in any orientation and does not require extra and external
lubricating devices. Use the table below for general guidelines. The unit should
remain sealed and protected from contamination at all times. Any maintenance or
service should be done in a clean environment.

Preparation of parts:
Use disassembly instructions below to gain access to parts for lubrication.
All oil and grease must be completely removed from all components
before applying lubricants.
All components must be clean and dry.
Do not use kerosene or any petroleum based cleaning fluids.
