This page covers the Optibelt C 138 VB classical V-belt, a C-profile belt with a 3607 mm length. It is intended for maintenance and purchasing teams that need to match an existing drive belt by its markings. The same size is also listed under Mitsuboshi C 138.
To match this belt to the one being replaced, start with the marking on the back of the old belt. Look for the profile letter and the length number: C and 138. Then confirm the physical dimensions of the new belt against the old one. The Optibelt C 138 VB has a top width of 22 mm, a height of 14 mm and a 40° angle. Its length is 3607 mm.
A C-profile classical V-belt is a common choice for industrial drives where a standard cross-section is required. If the old belt is worn, stretched or damaged, the marking may be difficult to read. In that case, measure the top width and height with a caliper and compare them to the values above. The length can be checked against the drive's pulley spacing or by measuring the old belt with a belt gauge.
When you request a quote, send the part number C 138 and the brand Optibelt. If you are replacing a belt from another brand, include that part number as well so the team can help confirm the right belt or suggest an equivalent. The same size is also listed under Mitsuboshi C 138.
