Caged Ball Profile Rail Technical Information
PRELOAD AND CLEARANCE
The NARC / NHRC linear guides provide the following 4 different preload classes: VC, V0, V1 and V2.
VC = Smooth motion, low friction
V0 = For precision situations, smooth motion
V1 = High stiffness, precision, high load situations
V2 = Super high stiffness, precision, super high load situations
The NARC / NHRC linear guides provide 5 different classes of precision: N, H, P, SP, and UP class. Engineers can choose a different class depending on machine applications.
