The sprocket code consists of the following elements:
Pitch/ number of teeth + type
M = with support fingers
S = with closed belt support
Z = without belt support
N = finger wheel for high cam traction belts
G = combination wheel suitable for every type of traction belt
K = cage roller
All sprockets are splittable (unless otherwise stated) and therefore easy to assemble.
Low profile belts (types S and DS) can also be driven by friction rollers. These are cage rollers (type K) and rubber rollers (type RR). It is essential that the web is tightly held around the roller. If necessary, this can be done by fitting a pressure roller near the drive roller.
