Key Features

Crowned Outer Profile

The curved outer ring provides a specialized contact geometry for guiding and rolling applications. Its suitability depends on the mating surface and operating conditions.

Fully Polymer Ring Construction

Both the inner and outer rings are manufactured from UHMWPE, offering low weight, corrosion resistance, and good chemical resistance in many industrial environments.

Glass Rolling Elements

Glass balls eliminate metallic rolling elements and provide corrosion-resistant performance for applications where metal components may be undesirable.

UHMWPE Bearing Cage

The UHMWPE cage separates and positions the glass balls, supporting controlled rolling movement within the bearing assembly.

Lightweight Design

The combination of UHMWPE components and glass balls provides a lightweight alternative to conventional metal bearing assemblies.

Custom Machining

SUNTRON manufactures engineering plastic rollers and bearings according to customer drawings, including customized dimensions, materials, and outer profiles.

1. What is a UHMWPE crowned guide roller?

A UHMWPE crowned guide roller is a polymer rolling component featuring a curved outer profile. It can be used in compatible guiding, conveying, and mechanical movement systems.

2. What materials are used in this bearing?

The inner ring, outer ring, and bearing cage are manufactured from UHMWPE. The rolling elements are glass balls.

3. What are the dimensions?

The standard dimensions of this model are 30 mm outer diameter, 14 mm inner diameter, and 12 mm overall width.

4. Why are glass balls used instead of steel balls?

Glass balls provide a non-metallic rolling element option with good corrosion resistance. Their suitability depends on operating load, speed, impact, and environmental conditions.

5. What is the advantage of the crowned outer ring?

The curved outer profile provides a specific rolling contact geometry that can be useful in certain guiding applications. Proper alignment and contact conditions depend on the mating component.

6. Can this bearing operate in wet environments?

UHMWPE offers good moisture resistance, while glass balls provide corrosion resistance. However, the complete bearing assembly should be evaluated according to the actual operating conditions.

7. Can SUNTRON manufacture different sizes?

Yes. SUNTRON offers custom machining for UHMWPE rollers and bearings, including different diameters, widths, bore sizes, and outer profiles.

8. What information is required for a quotation?

Please provide the required dimensions or technical drawings, order quantity, operating temperature, load requirements, and application details.
