The Dodge V-belt pulley of the Taper-Lock line is a power transmission component that mounts on the motor or driven machine shaft and, together with the belt, defines the speed ratio of the system. Its split taper bushing allows it to be fastened and removed without hammering the shaft or overheating the pulley, something maintenance teams appreciate. MR Accesorios Industriales supplies it in Buenos Aires, Argentina.

The designation of these pulleys is read in two parts. The first number indicates the number of grooves: 3B and 4B correspond to three-groove and four-groove pulleys respectively. The letter B defines the belt section. The number after the decimal point is the pitch diameter in inches, and the last block identifies the corresponding Taper-Lock bushing: 3020 or 3030. Thus, a 3B25.0–3020 is a three-groove, B-section pulley, 25 inches pitch diameter, with a 3020 bushing.

These pulleys are used in industrial fans, centrifugal pumps, compressors, conveyors and mills, and in driving process equipment in food, chemical and water treatment plants. In the Argentine market they appear both in new installations and as replacements in lines that have been running for decades, where the availability of the correct diameter and bushing defines whether the machine goes back into production or stays down.

To select correctly, start from the power to be transmitted, the motor and machine RPM, and the shaft diameter. The Taper-Lock bushing is chosen by shaft diameter and fastened with the bolts that clamp it against the pulley cone. Check alignment between pulleys with a straightedge or laser before tensioning, make sure the belt is not twisted and check tension according to the equipment manual. A misaligned pulley punishes belts and bearings.

As for interchangeability, V-groove pulleys with taper bushing are available from several brands and pitch diameter and section dimensions usually match between equivalent lines. The key is to respect the combination of number of grooves, section, pitch diameter and bushing type. If you need to replace an existing pulley, send us the part number stamped on the part or the measurements taken on the equipment and we will tell you the compatible alternative.
