The Optibelt PJ 1285 RB is a Poly-V (multi-rib) belt with a PJ profile and a length of 1285 mm. The profile and length are the two dimensions to match when replacing a worn or damaged belt.
The PJ profile identifies the rib pitch and cross-section, while 1285 mm is the datum length. To confirm a replacement, read the marking on the back of the old belt and compare both values with this listing. If the marking is worn away, measure the old belt and send the profile and length with your request.
Poly-V belts are used where a thin, flexible belt must grip across multiple ribs, such as in compact drives with small pulleys. Inspect the ribs for cracking, glazing or missing material, and check pulley grooves for wear or debris before fitting a new belt. On drives with more than one belt, replace the full set so the load stays evenly shared.
We carry the Optibelt PJ 1285 RB for maintenance, engineering and purchasing teams in the US, Canada, Mexico and South America. Send the part number and the quantity you need by WhatsApp or email, and our team will reply promptly to confirm the belt or suggest an equivalent.
