Description

The 400 4C pulley is a V-belt drive component with a 400 mm diameter and four grooves for section C belts. It transfers torque from a motor to a driven shaft and sets the speed ratio between the two pulleys. Manufactured in-house under the EMMAR brand, it is intended for drives that need proper alignment, balancing and reliable belt grip.
With a 400 mm diameter, four grooves and a section C profile, this pulley accepts up to four C-section V-belts. Section C is a wide-pitch profile used in medium and high power drives. Because it is made in-house by EMMAR, the pitch diameter and groove width can be checked against the technical data sheet before the pulley leaves the shop.
Typical installations include mills, mixers, compressors, centrifugal pumps, fans, conveyors and agricultural or plant equipment where belt drives multiply or reduce speed. In these setups, the 400 mm pulley usually mounts on the driven shaft while a smaller pulley drives it. Distributing the load across four belts helps lower vibration and even out wear in the drive.
When selecting this pulley, start with the motor power, the RPM and the required transmission ratio. Confirm that the 400 mm diameter fits the available space and that the shaft diameter matches the bore. Align the pulleys with a straightedge or laser, and tension the belts according to the belt manufacturer's instructions. Even a few millimeters of misalignment can cause uneven groove wear and noise. If a taper bushing is used, tighten the screws in a cross pattern with a torque wrench.
If you need a different number of grooves or a bore for another shaft, send the outside or pitch diameter, groove count, section and shaft diameter. We can locate an equivalent in our in-house manufacturing line or offer a custom pulley. We can also review whether an existing pulley can be replaced by one with similar characteristics without modifying the drive.

Frequently asked questions
- What does section C mean for this pulley?
- Section C is the V-belt profile that fits the grooves of this pulley. It determines groove width and depth, so only section C belts should be used. It is not interchangeable with sections A, B or D.
- Can I replace a 3-groove pulley with this 4-groove one?
- Yes, if the diameter and shaft match and the drive can accept one more belt. The extra groove improves load distribution. Check that the driving pulley uses the same section and that the transmission ratio stays the same.
- How do I request a pulley with a different shaft size?
- Send the shaft diameter, number of grooves and section by WhatsApp. With those details we can quote an in-house manufactured pulley with the bore and keyway you need.
