The Optibelt 4-A 3658 is a banded V-belt from the KB VB series with a length of 3658 mm. This page gives maintenance and purchasing teams the profile and length details needed to match an existing drive belt.
The 4-A profile identifies a banded V-belt with multiple A-section ribs joined into one unit. The 3658 mm length is the datum length for this belt. Use both the profile and the length when comparing against the marking on the belt you are replacing.
Banded V-belts are used where several V-belts run in parallel and must stay aligned. The banded construction keeps the ribs together, which helps during installation on multi-groove drives. Confirm that the drive uses a 4-A section and that 3658 mm matches the original belt before ordering.
When you request a quote, send the part number 4-A 3658 and, if possible, a photo of the belt marking. Our team can confirm the belt or suggest an equivalent based on the profile and length.
