This Optibelt B 199 belt is a classical V-belt in the VB / Red Power series. The profile and length are the two dimensions that matter most when you are matching a belt to a drive: profile B sets the cross-section, and 5131 mm is the datum length.
The B profile is a 17 mm top width and 11 mm height, with a 40° angle. Those three dimensions determine how the belt sits in the pulley groove. If the belt you are replacing has the same profile and a 5131 mm length, this Optibelt B 199 is the same size.
The same size is also listed under Gates B 199. If you are working from a drive that currently runs that size, you can compare the marking on the back of the old belt against the profile and length above before you request a quote.
For a quote, send the part number B 199 and the quantity you need. If you are unsure whether this is the correct belt for the drive, include the profile and length from the old belt and the team can help confirm it.
