Round Belts & Pulleys

Round belts are circular cross-section belts used in a variety of applications due to their flexibility and efficiency in power transmission.

Flexibility and Versatility

Round belts can easily adapt to pulley grooves of various shapes, making them highly versatile for different mechanical setups.

Material Options

They are often made from rubber, polyurethane, and other elastomers, offering a range of properties such as elasticity and abrasion resistance.


Commonly used in light-duty applications such as office machinery, food processing equipment, and textile machinery.

Maintenance and Longevity

Regular inspection and lubrication are necessary to maintain the integrity and performance of round belts and pulleys.


Round belts can be customized in terms of diameter, length, and material composition to meet specific operational needs.

Types of V-Belt Pulleys

V-belt pulleys are designed to work with V-belts for efficient power transmission in various mechanical systems.

Single Groove V-Belt Pulleys

These are the most common type, used in applications where a single belt is sufficient to transmit power.

Double Groove V-Belt Pulleys

Ideal for applications requiring higher power transmission, these pulleys accommodate two parallel belts.

Triple Groove V-Belt Pulleys

Designed for heavy-duty applications, they allow for the distribution of load across three belts, reducing wear and tear.

Variable Speed V-Belt Pulleys

These pulleys allow for adjustable speed ratios, providing flexibility in applications where varying speeds are required.

Flat Belt V-Belt Pulleys

Used in conjunction with flat belts, these pulleys offer a smooth transmission surface, reducing vibration and noise.

V-Belt Pulley Components

V-belt pulleys consist of several key components, each playing a crucial role in their overall functionality and efficiency.


Grooves are the channels where the belts sit. Their design and dimensions are critical for ensuring proper belt alignment and grip.


The hub is the central part of the pulley that connects to the shaft. It must be precisely machined to ensure a secure fit.


Flanges help to keep the belt aligned within the grooves, preventing it from slipping off during operation.


Keyways are slots that accommodate a key to secure the pulley to the shaft, ensuring torque transmission without slipping.


The bore is the hole through which the shaft passes. It must be accurately sized to match the shaft diameter for a proper fit.

How to Choose or Customize the Right Belt Pulley

Selecting the appropriate belt pulley involves considering several factors to ensure optimal performance and longevity.

Load Requirements

Determine the load that the pulley will need to handle. This includes both the initial startup load and the operational load.

Speed Ratio

Consider the desired speed ratio between the driving and driven shafts. This will influence the pulley diameter and groove design.

Environmental Conditions

Assess the operational environment, including temperature, humidity, and exposure to chemicals, to select suitable materials and coatings.

Belt Type

Choose a pulley that is compatible with the type of belt being used, whether it's a V-belt, round belt, or flat belt.

Custom Specifications

For specialized applications, customize the pulley dimensions, materials, and surface treatments to meet specific requirements.
