- Reinforced steel core for stability
Each drum is made from a high-strength steel core that ensures excellent load-carrying capacity, minimal deformation under pressure and long-term structural integrity, even in continuous operation.
-
High quality polyurethane coating
The outer polyurethane layer provides optimum wear resistance, low rolling resistance and low noise. Shore hardness (from 35A to 85D) can be customized to meet your specific application.
-
Precision mounted bearings
Equipped with high performance ball bearings for smooth rotation and low friction. Ideal for use in conveying, sorting and measuring systems where speed and stability are critical.

What applications is this PU tumbler suitable for?
These polyurethane rollers are widely used in heavy equipment, logistics conveyor lines, automated machinery, packaging equipment, printing machinery, electronic assembly lines, etc. They are especially suitable for working environments with high requirements for load carrying capacity, abrasion resistance and buffer performance.
-
What is the load capacity of the rollers?
The specific load carrying capacity depends on the roller size, bearing specification and steel core structure. Conventional products can carry from tens of kilograms to hundreds of kilograms per roller. If you need precise load parameters, we suggest that you provide the working conditions, we can make recommendations for selection.
-
What material is used for the PU rubber layer? Is it wear-resistant?
We use high-performance cast polyurethane material with excellent abrasion resistance, oil resistance and anti-aging ability. The hardness can be customized according to customer needs, commonly 85A, 90A, 95A, etc., which can ensure load bearing and provide good cushioning and shock absorption.
-
Does the steel core material rust? How is it protected?
The steel core part is generally made of No.45 steel or 40Cr material, which is molded by CNC machining, and the outer layer can be rust-proofed according to the requirements, such as blackened, electroplated or spray-painted, and stainless steel can be selected for some high-requirement occasions to further enhance the corrosion-resistant performance.
