The 230 5B pulley is a V-belt drive pulley, section B, with a 230 mm diameter and 5 grooves. It is used to drive shafts from a motor, reduce or increase speed, and distribute power among several machines. It is in-house manufacturing, EMMAR brand, so it is produced with the machining and balancing each application requires. If you need to replace a worn pulley or build a new drive, this size covers a range of power ratings common in factories and industry.

This item is a pulley with a 230 mm diameter, 5 grooves and section B. Section B defines the belt profile the pulley accepts; the 5 grooves allow mounting up to five belts in parallel on the same disc. The 230 mm diameter is the outside diameter of the pulley and, together with the motor pulley, determines the drive ratio. It is a machined cast part, with ground grooves so the belt seats evenly and does not slip.

It is used in V-belt drives on machine tools, compressors, fans, pumps, belt conveyors and plant equipment. When the motor delivers high power or the shaft has heavy flywheels, the 5 grooves distribute the load among several belts and reduce the tension on each one. It also serves to correct an existing drive ratio: by changing the diameter of the driving or driven pulley, the final speed of the equipment is adjusted.

To choose it correctly, check the shaft diameter and keyway type, the outside diameter that fits in the available space, and the belt section you already use. The pulley is mounted with a key and fixed axially; it is advisable to check alignment between pulleys with a straightedge or laser so the belts do not wear on one side. Tension is adjusted according to the equipment manual, without over-tightening so as not to load the motor bearings.

If you cannot find the exact part number or need another size, send us the diameter, the number of grooves and the belt section. We can also manufacture a custom pulley if the shaft or keyway do not match the standard. We have been working in the field for more than 80 years, so if you send us a photo of the old pulley or the shaft drawing, we will help you define the part that replaces the current one.

MR Accesorios Industriales manufactures this pulley and sells it together with belts, bearings and housings to build the complete drive. To request a quote, send the part number POLEA 230 5B by WhatsApp and we will confirm alternatives. If the equipment is down, tell us which belt you use and which diameter you need, and we will guide you so the pulley fits without modifying the assembly.

Frequently Asked Questions

What does section B mean?
Section B is the V-belt profile that fits into the grooves. It defines the width and depth of the groove, so a belt of another section does not seat properly. This pulley takes section B belts, and you can mount up to five in parallel.
Can I replace a 4-groove pulley with this 5-groove one?
Yes, as long as the outside diameter and the shaft bore match the assembly. With five grooves you can use five belts or fewer; if you leave grooves empty, the pulley still works. Check that the space and the equipment tension allow it.
How do I order a pulley with another diameter or number of grooves?
Send by WhatsApp the outside diameter, the number of grooves, the belt section and the shaft diameter with keyway. With that data we will quote an in-house manufactured pulley in the size you need, without having to adapt the equipment.
