Roller carriage installation instructions

GN 2426 cam rollers are combined with GN 2422 roller guide rail to build individual and space-saving linear roller guide systems.
Outer rim surfaces of the rollers are slightly convex, so that in conjunction with the correspondingly-shaped bearing rails (Type XT or XV) there is an accurate and smooth run across four contact points. The same applies to floating bearing rails (Type UT or UV), but with only two contact points.
Combined with the rail, clearance freedom or the initial tension of several rollers can be determined during assembly by using the adjustable eccentrical roller (Type E). The required open-end wrench, GN 2424.1 (middle of page), is available separately.
The sealed and permanently lubricated rollers guarantee long service life and superior running performance.

Available upon request:
• alternate type of sealing discs, steel metal profiles with gap seal (Type 2Z)
