This Optibelt RB belt is a poly-V (multi-rib) belt with a PJ profile and a length of 280 mm. The profile and length are the two dimensions to match when selecting a replacement.
The PJ profile identifies the rib pitch and cross-section of the belt, so it must match the pulley groove profile on the drive. The 280 mm length is the datum you compare against the belt you are replacing. If the old belt is worn or the marking has rubbed off, measure the length and confirm the profile before ordering.
Poly-V belts are used where a thin, flexible belt needs to wrap small pulleys and transmit load across multiple ribs. Inspect the ribs for cracking, glazing or missing material, and check the pulleys for wear or debris that can shorten belt life.
To request a quote, send the part number PJ 280, the quantity, and any details from the back of the old belt. If you are unsure of the profile or length, our team can help confirm the right belt or suggest an equivalent.
