Custom Polyurethane Pulleys

Zhongde manufactures custom polyurethane pulleys for industrial equipment and material handling systems. We customize outer diameter, bore size, groove profile, hardness, and other specifications based on your drawings or samples, with PU formulations selected according to application needs.

What Can We Customize in Polyurethane Rollers?

Your roller’s performance depends on more than its dimensions. Hardness, core material, polyurethane formulation, surface finish, and overall geometry all affect traction, wear, load capacity, and service life. We review your drawings before tooling to identify practical adjustments for molding, bonding, and dimensional control. Here’s what you can customize:

Types

We customize polyurethane pulleys in different configurations to suit drive systems, conveying equipment, and material-handling applications. Available types can be selected according to the pulley’s contact function, mounting structure, and operating requirements.

Common options include:

Drive Pulleys
Idler Pulleys
Guide Pulleys
Grooved Pulleys
Flat Pulleys
Flanged Pulleys

Core Materials

We can help you evaluate core materials based on your pulley design, load requirements, mounting method, and operating environment. For example, aluminum may be suitable when reducing rotating mass is a priority, while steel may be preferable when greater core rigidity is required.We also consider shaft-fit tolerances, corrosion exposure, and the bonding requirements between the core and polyurethane layer.

Available choices include:

Aluminum
Carbon Steel
Stainless Steel
POM (Acetal)

Hardness

Polyurethane pulleys used in light-duty guiding systems may require different hardness levels than those operating under heavier loads. We offer hardness customization to accommodate variations in contact pressure, deformation limits, and operating conditions, common options include 70A, 80A, 90A, and 95A Shore A.

Colors

Color selection can help distinguish pulley types, identify equipment components, and maintain a consistent product appearance. Customers can choose a suitable color based on their application, with RAL or Pantone references available to help communicate color preferences.

FAQs of Custom Polyurethane Pulleys

View our FAQ center for more questions.

What is the difference between polyurethane pulleys and rubber pulleys?

Polyurethane pulleys generally offer better abrasion resistance and load-bearing capability than many conventional rubber compounds. Rubber may be preferable when greater flexibility, vibration damping, or specific chemical resistance is required.

Can polyurethane pulleys be bonded to aluminum or steel cores?

Yes. Polyurethane can be bonded to properly prepared metal cores. Surface preparation, primer selection, and molding conditions influence bond strength and should be evaluated for the specific material combination.

Can you customize the bore and mounting features?

Yes. Bore diameter, keyways, mounting holes, and other interface features can be customized according to your assembly design. Critical dimensions should be specified on the drawing to support fit verification.

Can you manufacture replacement polyurethane pulleys for existing equipment?

Yes. We can assess an existing pulley using customer-provided drawings, measurements, or a physical sample. Information about the shaft interface, operating load, and wear pattern can help determine suitable replacement specifications.
