The K1 Lubrication Unit is available in two types, one forindustrial applications and one for food and medicaldevices where cleanliness and safety are paramount. Features:1. Long-term, maintenance-free mechanical environments where lubrication is difficult to apply, long-term running efficiency is maintained by using the NSK K1 in combinationwith Prevention of oil-related environmental locations where oil greatly affects the environment, or in mechanisms with severe hygiene restrictions,sufficient lubrication is provided using the NSK K1 in combination with Effective in environments where the lubricant is washed facilities where mechanisms are washed down with water, or subject to severe weather conditions.

5 Long service life is ensured by using the NSK K1 in combination with grease. Especially effective underhygienic conditions where oil must not be Maintains efficiency in dusty environments where oil and grease-absorbing dust is produced, long-term efficiency is maintained by using the NSK K1 in combination with Dimensions with K1 Assembly Instructions K1 Lubricating Unit for Linear GuidesInterchangeableStandard Ball slide length ThicknessThickness ofGrease fittingBall SlideBall slideBall Slide with two NSK K1 of NSK K1 protective coverprojectionsize codeformlengthLV1V2N (mm)
