250mm Large Diameter UHMWPE Plastic Ball Bearing with Stainless Steel Balls

Large Diameter. Lightweight Construction. Precision Polymer Bearing.

This 250mm large diameter UHMWPE ball bearing is designed for industrial equipment requiring oversized polymer bearing components, corrosion-resistant materials, and smooth rotational movement.

Manufactured with precision-machined UHMWPE inner and outer rings and stainless steel rolling elements, this bearing provides a lightweight alternative to conventional all-metal bearings.

Its large-diameter, open ball bearing construction makes it suitable for evaluation in specialized rotating assemblies, industrial automation, and custom machinery.

Key Features

1. Large Diameter Polymer Bearing Design

With a 250mm outer diameter, this bearing is designed for applications requiring larger-than-standard bearing dimensions.

Its customized construction provides an alternative for industrial equipment where conventional catalog bearings may not fit.

2. UHMWPE Inner and Outer Rings

Both bearing rings are manufactured from Ultra High Molecular Weight Polyethylene (UHMWPE), offering:

• Excellent abrasion resistance

• Low friction characteristics

• Lightweight construction

• Low moisture absorption

• Good resistance to many industrial chemicals

These properties make UHMWPE suitable for selected industrial bearing applications.

3. Stainless Steel Rolling Elements

The bearing incorporates stainless steel balls to provide rolling contact between the polymer rings.

Stainless steel rolling elements offer good corrosion resistance, depending on the selected grade and operating environment.

4. Lightweight Alternative to Metal Bearings

UHMWPE has a significantly lower density than steel, helping reduce the overall weight of large-diameter bearing assemblies.

This can be beneficial for equipment requiring lightweight rotating components.

5. Precision CNC-Machined Construction

SUNTRON manufactures large-diameter polymer bearings through precision CNC machining.

The inner and outer rings are machined to achieve the required raceway geometry, dimensional accuracy, and assembly compatibility.

6. Custom Bearing Manufacturing

We support custom bearing dimensions, material combinations, ball configurations, and specialized structures according to customer drawings.
