NSK Linear GuidesTM Roller Guide Equipped with V1 Seal

NSK K1TM Lubrication unit

Porous resin Containing a large amount
of lubrication oil

Enlarged view of NSK K1 V1 Seal Retainer plate Highly abrasion-resistant material used for seal lip

Made of porous synthetic resin containing Seal lip
a large amount of lubrication oil.
When moved through contact with
the raceway surface, it supplies fresh
lubricating oil.

Rail cover

Abrasion amount, mg

Presser plate New material Existing material

Covers the top surface of the rail and Taper abrasion test (ASTMD1044)
prevents foreign matter from entering in Load: 9.8 N
rail mounting bolt holes. Average speed: 29.7 m/min, Approx. 40 km/day

V1 Seal made of new materials and in a new shape for better abrasion resistance prevents
foreign matter getting into the roller slide for a long period.

■ Durability test under extreme conditions - no lubrication V1 Seal Existing end seal

With this new material, even if lubrication is poor, damage Slight wear Abrasion
such as roughening of surfaces will not occur.
