Description
EMMAR POLEA 400 4B belongs to pulleys, part of our Power transmission range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for POLEA 400 4B and any equivalents.
The POLEA 400 4B is a V-belt drive pulley with a 400 mm diameter and 4 grooves for section B belts. It transmits power between parallel shafts in industrial equipment, providing a stable transmission ratio and the ability to run multiple belts in parallel. Manufactured in-house under the EMMAR brand, the machining can be tailored to your required size and keyway type.
The part number POLEA 400 4B encodes three key variables: diameter, number of grooves, and belt section. The 400 indicates the diameter in millimeters, the 4 stands for the number of grooves, and the B specifies the V-belt profile. Section B is a common profile in industrial power transmission. With four grooves, the pulley accommodates four belts side by side on the same diameter, distributing the load across them.
This pulley is found in belt-driven equipment such as fans, compressors, pumps, mills, mixers, and conveyors. It also appears in agricultural machinery and implements where a large diameter is needed to reduce speed or increase the speed of the driven shaft. Because groove wear or edge damage can harm belts, it is a frequent replacement item in maintenance schedules.
When selecting a pulley, consider the outside diameter, number of grooves, and the belt section you already use. Verify the shaft diameter and keyway type, and ensure the pulley fits in the available space without interfering with the structure. If you plan to change the transmission ratio, also review the driven pulley and belt length. Proper alignment and belt tension according to the equipment manual are essential during installation.
If you need a different number of grooves or a different section, an equivalent or custom pulley can be requested. To do so, provide the POLEA 400 4B part number or the original pulley data: diameter, grooves, section, and shaft diameter. With that information, we can identify the best option from our in-house manufacturing line or evaluate special machining.
