Plastic Bearing Balls 1/2 inch G2 Precision 25pcs POM uxcell

Description

Product Overview

uxcell’s 1/2 inch (12.6 mm) plastic bearing balls are engineered for precision and durability in a wide range of mechanical applications. Each ball is molded from high‑performance polyoxymethylene (POM), a thermoplastic known for its low friction coefficient, excellent wear resistance, and dimensional stability across temperature variations. The balls meet the G2 accuracy grade, delivering a roundness tolerance that ensures smooth rotation and minimal vibration in bearings, gear transfers, and slide mechanisms. With a compact size of 0.5 × 0.5 × 0.5 inches and a weight of just 1.44 ounces per piece, they are lightweight yet robust enough to handle demanding industrial loads. The package contains 25 individually inspected balls, each bearing the uxcell brand and a unique model number for easy inventory tracking. Their smooth surface finish reduces the need for additional lubrication, while the POM material resists corrosion, chemicals, and moisture, making them suitable for both indoor and outdoor environments. The balls are compatible with standard bearing housings, universal ball transfers, and conveyor accessories, providing a versatile solution for engineers, hobbyists, and maintenance technicians alike. By adhering to strict quality control standards, uxcell ensures that every ball delivers consistent performance, contributing to longer equipment life and reduced downtime. Whether used in robotics, 3D printers, agricultural sprayers, or heavy‑duty industrial machinery, these precision balls offer reliable operation and cost‑effective maintenance. According to the manufacturer, the balls have a hardness rating of approximately 85 Shore D, which further enhances their resistance to surface deformation under load. The product’s best‑seller rank of #198,813 in the Industrial & Scientific category and #17 in Plastic Precision Balls reflects its popularity among professionals seeking high‑quality components at an affordable price point.

The 25‑piece set is packaged in a recyclable cardboard box, designed for easy storage and quick access during assembly or repair tasks. With a price of $7.69, the uxcell bearing balls provide an economical alternative to metal bearings in applications where weight reduction and corrosion resistance are critical.

Usage

These plastic bearing balls excel in environments where low friction and high durability are essential. In industrial settings, they are commonly installed in linear guides, conveyor rollers, and gearboxes to reduce wear and extend service intervals. Their corrosion‑resistant POM composition makes them ideal for outdoor machinery, agricultural equipment, and marine applications where exposure to moisture or chemicals could degrade metal components. Hobbyists appreciate the balls for 3D printer extruder assemblies, CNC machine sliders, and custom robotics projects, where precise motion and quiet operation are prized. Maintenance technicians often replace worn metal bearings with these plastic alternatives to lower overall system weight and simplify part inventories. The 1/2 inch diameter fits standard bearing housings, allowing quick retrofits without extensive redesign. Because the balls operate smoothly without additional lubrication, they are suitable for clean‑room environments and food‑processing lines where oil‑based lubricants are prohibited. Their versatility also extends to educational settings, where they serve as tangible examples of material science concepts such as friction, wear, and precision engineering. By integrating these balls into design, engineers can achieve reliable performance while minimizing cost and environmental impact.

FAQ

What makes POM a better choice than metal for these bearing balls?

POM (polyoxymethylene) offers a unique combination of low friction, high wear resistance, and chemical stability. Unlike metal, it does not corrode, is lighter, and operates silently, making it ideal for applications where weight, cleanliness, and quiet operation are important.

Can these balls be used in high‑temperature environments?

POM maintains its mechanical properties up to approximately 180 °C (356 °F). For most industrial and hobby applications that stay below this temperature, the balls perform reliably. If temperatures exceed this range, a metal bearing may be required.

How do I install the 25‑piece set in my equipment?

Each ball is ready to mount directly into standard bearing seats or cages. Simply clean the housing, place the ball, and ensure it sits evenly. No additional lubrication is needed unless the design specifically calls for it.

What warranty or support does uxcell provide?

uxcell offers a 12‑month limited warranty covering material defects and workmanship. Customers can contact the support team for replacement parts, technical advice, or documentation, ensuring peace of mind throughout the product’s lifespan.

Are these balls compatible with metal bearing housings?

Yes, the 1/2 inch diameter conforms to common metal bearing standards, allowing seamless integration with existing metal housings. The POM balls will not damage metal surfaces and can operate alongside metal components without adverse effects.
