OPTIBELT B 123 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 B 123 and any equivalents.
The Optibelt B 123 is a classical V-belt in the VB / Red Power series with a B profile and a 3200 mm length. Before you fit a new belt, inspect the drive and sheaves so the replacement runs true.
Check sheave grooves for wear, burrs, or debris, and confirm the grooves match the B profile. A worn or damaged sheave can shorten the life of any new belt, so correct any issues before installation.
Verify alignment between sheaves and check that the drive is free of obstructions or excessive play. The B 123 has a top width of 17 mm, a height of 11 mm, and a 40-degree angle, and it measures 3200 mm in length.
The same size is also listed under Stark B 123 and Gates B 123. When you request a quote, send the part number and any drive details so we can help confirm the right belt.
