OPTIBELT SPB 4250 belongs to v-belt, part of our Power transmission range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for SPB 4250 and any equivalents.
The Optibelt SPB 4250 is a narrow wedge V-belt in the SK metric profile series. It has an SPB profile, a 4250 mm length, a 16.3 mm top width, a 13 mm height and a 40 degree angle. Before fitting this belt, inspect the drive and sheaves.
Check sheave grooves for wear, cracks, or embedded debris. Worn grooves can cause a new belt to slip or seat incorrectly. Confirm the sheave groove profile matches the SPB profile and that the groove angle is compatible with the belt's 40 degree angle. Misalignment between sheaves should be corrected before installation.
Verify that the replacement belt matches the old belt's marking. The Optibelt SPB 4250 carries the SPB profile and 4250 mm length. The same size is also listed under Mitsuboshi SPB 4250 and Stark SPB 4250. If you are replacing a set, fit all belts at the same time and check tension after run-in.
