uxcell 10pcs POM Plastic Bearing Balls, 11/16″(17.3mm) Solid Plastic Balls G2 Precision Polypropylene Mini Ball, Black

Description

Product Overview

The uxcell 10pcs POM Plastic Bearing Balls are engineered to provide consistent, high‑quality performance across a broad spectrum of industrial and scientific applications. Each ball measures 11/16″ (17.3mm) in diameter and conforms to the G2 accuracy grade, guaranteeing a near‑perfect spherical geometry that minimizes vibration and maximizes load distribution. Constructed from premium polyoxymethylene (POM) resin, also known as engineering plastic or acetal, these balls exhibit exceptional dimensional stability, low moisture absorption, and a smooth, low‑friction surface that reduces wear on mating components.

Technical specifications include a weight of 1.44 ounces per set, a compact cubic packaging dimension of 0.68 x 0.68 x 0.68 inches, and a robust manufacturing process that ensures each ball meets strict tolerance limits. The product is listed under the Industrial & Scientific category, specifically within Raw Materials > Plastics > Spheres > Precision Balls, reflecting its suitability for precision engineering tasks. With an ASIN of B0FPGBJ3F8 and a best‑sellers rank of #57 in Plastic Precision Balls, the uxcell bearing balls have earned a reputation for reliability among engineers, hobbyists, and maintenance professionals alike.

Beyond the core dimensions, the POM material offers inherent chemical resistance, making these balls suitable for environments where exposure to oils, solvents, or mild acids is common. The non‑metallic nature eliminates the risk of rust, galvanic corrosion, or magnetic interference, which can be critical in sensitive equipment such as medical devices, optical instruments, or electronic assemblies. The black coloration not only provides a sleek aesthetic but also helps conceal surface contaminants, contributing to longer service intervals and reduced downtime.

Usage

These precision plastic balls are versatile enough to be employed in a wide array of mechanical systems. In bearing assemblies, they serve as rolling elements that support radial and axial loads while maintaining low friction, extending the lifespan of shafts, spindles, and rotary tables. Their smooth surface makes them ideal for drawer slide mechanisms, where quiet operation and smooth glide are paramount for office furniture, cabinetry, and industrial storage solutions.

In gear applications, the balls can be used as replaceable elements in gear reducers, planetary gear sets, and timing mechanisms, providing consistent torque transmission and reducing noise levels. The universal ball transfer units, commonly found in conveyor systems and material handling equipment, benefit from the POM balls’ ability to handle multidirectional loads without deformation, ensuring reliable movement of pallets, containers, and heavy parts across production lines.

Outdoor installations, such as agricultural machinery, irrigation equipment, and weather‑exposed conveyor components, also gain from the corrosion‑resistant properties of POM. The balls can be integrated into sprayer nozzles, pump housings, and valve assemblies where exposure to moisture and chemicals is routine. Additionally, hobbyists and makers often incorporate these balls into 3D‑printed prototypes, robotic joints, and custom‑built mechanisms, appreciating the balance of strength, low weight, and ease of machining.

When selecting the uxcell POM bearing balls, consider the operating temperature range of your application. POM maintains its mechanical properties from -40 °C to +120 °C, making it suitable for most ambient and mildly elevated temperature environments. For high‑speed rotations, the low density of the plastic reduces centrifugal forces, allowing higher RPM thresholds compared to metal counterparts. Users should also verify clearance requirements, as the precise G2 grade ensures tight tolerances that may necessitate matching housing dimensions.

FAQ

What is the difference between POM plastic balls and metal bearing balls?

POM balls are lighter, non‑magnetic, and resistant to corrosion, making them ideal for applications where metal balls could rust or interfere with magnetic fields. They also produce less noise and can operate at higher speeds due to lower inertia.

Can these balls be used in high‑temperature environments?

The POM material maintains its mechanical properties up to approximately 120 °C. For temperatures above this range, a different material such as ceramic or high‑temperature alloy may be required.

How do I determine the correct clearance for my bearing housing?

Consult the uxcell technical datasheet for recommended clearance values based on ball diameter and load conditions. Generally, a clearance of 0.02–0.05 mm per ball is suitable for most low‑speed applications.

Are the balls compatible with standard metal shafts?

Yes, the 11/16″ (17.3mm) diameter matches common shaft sizes used in many industrial machines. Ensure the shaft surface is smooth and free of burrs to prevent premature wear.

What warranty does uxcell provide for these bearing balls?

We offer a 12‑month limited warranty covering material defects and manufacturing errors. If you encounter any issues, contact our support team with the batch number for a replacement or refund.
