The Optibelt 2-B 2100 is a banded V-belt from the KB VB series, built to keep multiple V-belts running as a single unit on drives that cannot tolerate individual belt turnover or whip. This belt is 2100 mm long and uses the B profile. Before fitting it, inspect the drive and sheaves so the new belt is not damaged by worn components.

Start by locking out the drive and checking sheave grooves for wear, rust, or embedded debris. Worn grooves let the belt sit too deep, which reduces grip and can cause slippage or rapid wear. Misalignment between sheaves is another common cause of belt failure; use a straightedge or laser tool to check that the grooves line up. Also confirm that the sheaves are the correct profile for a B-section belt and that no groove is cracked or chipped.

Spin the sheaves by hand and feel for roughness, excessive play, or binding in the bearings. Check the bushing and key for tightness, and look for oil or grease leaks that could contaminate the new belt. If the drive uses a tensioner, verify that it moves freely and has enough travel to tension the belt properly. Any worn or damaged component should be replaced before the new belt is installed, because a new belt will wear quickly on a bad drive.
