The 120 1B is a single-groove V-belt pulley with a 120 mm diameter, built in-house under the EMMAR brand. It mounts on a shaft and drives section B belts, making it a compact option for straightforward power transmission layouts. Because it comes from our own production, the dimensions and balance are held to consistent tolerances.

Reading the designation is simple: 120 is the diameter in millimeters, 1B means one groove in section B. Section B is a classic V-belt profile found throughout industrial drives. With a single groove and this diameter, the pulley suits transmissions that need just one belt and a simple ratio.

You will see this size on machine tools, compressors, fans, centrifugal pumps, conveyors and general transmission equipment. In each case it goes on the motor or driven shaft and works as a pair with a matching pulley, linked by a section B belt. It fits installations where room is tight and a compact drive is preferred.

Selection comes down to pitch diameter, groove count and belt section. Check that the shaft diameter is correct and that the keyway lines up. Keep the shaft clean and free of burrs during mounting, and use the proper fasteners. Aligning both pulleys protects the belt from extra wear and keeps vibration down. Our team can walk you through any of this.
