RIBBED BELTS – PJ/J
TYPE RIBBED SLEEVES Ribbed belts are primarily used in drives with a high transmission ratio (1:40) where small-diameter pulleys (from 13 mm) are required, as well as in drives with multiple pulleys or sheaves. A further advantage is that they can be fitted to equipment requiring a higher peripheral speed (60 m/s) and a high-performance, compact transmission. The PJ/J ribbed belt is made from CR rubber and PA fabric. Temperature resistance: –30°C to +80°C.
Ribbed belts are manufactured as a tube, from which we then use a specialised cutting machine to produce the required belt with the specified number of ribs.
Standard types supplied:
rubber: PH, PJ/J, PK, PL, PM
polyurethane: TB2
Parameters for identifying the dimensions and type of PJ/J
belt e = 2.34 mm Pitch between individual teeth
h = 3.40 mm Belt
height α = 40° Angle of engagement
If you have an existing belt and the marking is legible, proceed as follows: ‘PJ’ (e.g. PJ914) indicates dimensions in mm, or if the marking is the letter ‘J’ (e.g. J360), it indicates dimensions in inches. Next, count the number of ribs. Please note! Do not confuse the number of ribs with the number of grooves. The belt marking always specifies the number of ribs (protruding wedges).
