uxcell 100pcs POM Bearing Balls 1/2″ (12.7mm) Precision Spheres

Description

Product Overview

The uxcell 100pcs POM bearing balls are engineered from high‑performance polyoxymethylene (POM) plastic, delivering a combination of low friction, high wear resistance, and outstanding dimensional stability. Each ball measures exactly 12.7 mm (½ in) in diameter, providing a consistent size that meets tight engineering tolerances across a wide range of industrial applications. The solid plastic construction eliminates the need for lubrication, reducing maintenance costs and simplifying system design. With a package dimension of 5.94 × 5.91 × 0.55 inches and a lightweight of 5.82 oz, the set is easy to store and handle, making it a convenient choice for both small‑scale workshops and large manufacturing facilities. The balls are resistant to corrosion, allowing them to perform reliably in humid, outdoor, or chemically aggressive environments. Their high abrasion resistance ensures long service life even under heavy load conditions, while the low coefficient of friction contributes to smoother motion and reduced energy consumption. Designed for versatility, these precision spheres are suitable for automotive components, machinery bearings, electronic assemblies, and many other precision engineering tasks. The product has earned a strong reputation on Amazon, reflected by a 5‑star rating from four verified customers and a Best Sellers Rank that highlights its popularity within the plastic precision balls sub‑category.

Usage

These POM bearing balls excel in a variety of real‑world scenarios. In automotive applications, they can be used as pivot points in steering linkages, gear shifters, and throttle control mechanisms where smooth, reliable rotation is essential. Machinery manufacturers rely on them for linear guides, conveyor rollers, and spindle bearings, benefiting from the material’s ability to withstand high speeds and repetitive motion without degradation. In the electronics sector, the balls serve as insulating spacers, connector components, and precision alignment tools, where their non‑conductive nature and dimensional accuracy prevent short circuits and ensure proper assembly. Outdoor installations, such as solar panel tracking systems or wind turbine components, also profit from the balls’ corrosion‑resistant properties, maintaining performance despite exposure to moisture and temperature fluctuations. Because the POM material does not absorb moisture, the balls remain stable in humid climates, eliminating the risk of swelling that can affect metal counterparts. Users should verify the 12.7 mm diameter before integrating the balls into their designs to ensure proper fit with housings, shafts, or cages. The lightweight nature of the plastic balls reduces overall system weight, which can be advantageous in applications where mass savings translate to improved efficiency or lower transportation costs.

FAQ

What material are these bearing balls made from?

The balls are manufactured from polyoxymethylene (POM) plastic, a high‑performance engineering polymer known for its low coefficient of friction, high wear resistance, and excellent dimensional stability.

Can these balls be used in high‑temperature applications?

POM retains its mechanical properties up to approximately 180 °C (356 °F). For most industrial and automotive uses that operate well below this temperature, the balls will perform reliably without deformation or loss of strength.

Are the balls suitable for outdoor or marine environments?

Yes. The POM material is highly resistant to moisture and many chemicals, making the balls suitable for outdoor installations, marine equipment, and other environments where corrosion could be a concern for metal components.

Do I need to lubricate these bearing balls?

No additional lubrication is required. The inherent low‑friction properties of POM provide smooth operation, reducing maintenance requirements and eliminating the risk of lubricant contamination.

How should I verify the correct size before ordering?

Measure the intended bearing housing or shaft groove to confirm a 12.7 mm (½ in) diameter clearance. Ensure that the tolerance range of the application accommodates the exact ball size to achieve optimal performance.
