Lubrication Unit NSK K1TM

• NSK K1 lubrication unit equipped with an NSK linear guide, ball screw and Monocarrier
is an outstanding new lubrication material.

• A Newly developed porous synthetic resin contains large volume of lubricant oil that
seeps out and enhances lubricating function.

NSK K1 lowers machine operation cost, and reduces impact on the environment.
NSK K1 is a lubrication device which combines oil and resin in a single unit. The porous resin contains a large
amount of lubrication oil. Touching its surface to the raceway of a rail close to the ball contact point NSK K1
constantly supplies fresh oil which seeps from the resin.

You can achieve Magnification of NSK K1
the following:

• Long-term maintenance-free (cost 100 μm
reduction)
Portion containing high
• Long life under severe environments proportion of lubricating oil
• Environmentally sound clean lubrication
Portion containing high
system proportion of polyolefin

Lubricant oil and polyolefin combined and
molded into one unit
• Containing 70% of lubrication oil
• Supplies lubricant oil for long periods of time

(Service life: in excess of 100 000 hours)
