This Mitsuboshi B 103 is a classical V-belt with a B profile. Before you fit it, inspect the drive: worn sheave grooves will shorten the life of any new belt, regardless of brand.
Check the sheaves for groove wear, rust, and oil. A straightedge across the pulley face shows whether the grooves have opened up. Misalignment between sheaves also wears the belt sides. Correct these points before installing the B 103, because a classical V-belt relies on the 40° angle and the 17 mm top width to wedge into the groove.
The belt has a height of 11 mm. Confirm that the replacement matches the old belt's profile and length by reading the marking on the back. If the drive runs multiple belts, replace them as a set so the load stays even.
We carry the Mitsuboshi B 103. The same size is also listed under Stark B 103 and Optibelt B 103. Send the part number and the quantity you need by WhatsApp or email, and we will confirm the belt or suggest an equivalent.

Frequently asked questions
- How do I confirm this is the right belt for my drive?
- Read the marking on the back of the old belt. It should show the B profile and the length. The B 103 has a 17 mm top width, an 11 mm height, and a 40° angle.
- What should I check on the drive before installing a new belt?
- Inspect the sheave grooves for wear, rust, and oil, and check that the sheaves are aligned. Worn or misaligned sheaves will damage a new belt.
- Can you supply the same size from another brand?
- Yes. The same size is also listed under Stark B 103 and Optibelt B 103. Send us the part number and quantity to confirm.
