Description
EMMAR POLEA 400 3C 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 3C and any equivalents.
The 400 3C is an EMMAR-manufactured V-belt pulley with a 400 mm diameter and three grooves for section C belts. It transmits power between parallel shafts in demanding industrial drives. Because it is made in-house, machining details can be adjusted to match the application. For a replacement or a new drive, send the part number POLEA 400 3C for a quote.
The code POLEA 400 3C tells you the three essentials: 400 mm diameter, 3 grooves, and a C section belt profile. Section C is larger than A or B and is used in higher-power drives. In-house production of this EMMAR pulley means groove machining and balancing are controlled for smooth operation at the speeds these drives typically run.
This pulley size suits equipment that moves substantial loads: screw compressors, large centrifugal pumps, industrial fans, mills, mixers, and conveyors. It also appears in continuous-process machines where speed must hold without slipping. Three grooves spread the load across three belts, reducing the strain on each one and promoting smoother running. It is a common size in plant equipment and in worn-pulley replacements.
Before mounting, confirm the shaft diameter and keyway match the pulley bore. Drive and driven pulleys must be aligned; angular or parallel misalignment speeds up belt and groove wear. Tension belts per the equipment manual or with a tension gauge, without over-tensioning that could overload bearings. If the pulley will run at high speed, it should be balanced. For selection, consider the power to transmit, shaft speed, and the section C belt you will use.
For an equivalent to the 400 3C, send the equipment data: diameter, number of grooves, belt section, and bore diameter with keyway. A photo of the old pulley or its part number also helps. With that, we propose a matching in-house manufactured pulley or machine one to size. Standard section C sizes are available, along with bore and groove variants.
To request a quote for the 400 3C pulley or ask about an equivalent, send the part number POLEA 400 3C by WhatsApp to MR Industrial Accessories. We will reply with the quote and alternatives. If you are unsure about the section or number of grooves, write to us and we will help you identify the correct pulley for your equipment.

Frequently asked questions
- What does 400 3C mean in the pulley designation?
- The 400 is the pulley diameter in millimeters. The 3 is the number of grooves, and the C is the V-belt section it accepts. This is a common way to identify belt drive pulleys.
- What type of belt does this pulley use?
- It uses section C V-belts. Section C is larger than A or B and is suitable for transmitting more power. Check that your belts are section C so they fit the grooves correctly.
- Can I request a pulley with a different bore diameter?
- Yes, because it is in-house manufacturing, the bore and keyway can be machined to match your equipment shaft. Send the shaft diameter, keyway width, and number of grooves you need to quote the variant.
