PP Plastic Bearing Balls 1/2 inch 12.7mm 50pcs G2 Grade by uxcell

Description

Product Overview

uxcell presents a pack of fifty 1/2 inch (12.7 mm) polypropylene (PP) bearing balls engineered to meet G2 precision standards. Each ball is molded from high‑quality PP, a polymer known for its excellent dimensional stability, low moisture absorption, and resistance to chemicals. The spherical geometry is tightly controlled to maintain a uniform diameter, ensuring consistent performance across a wide range of mechanical applications. At a lightweight 2.08 ounces per fifty‑ball set, the product offers an economical solution without compromising on durability. The balls are supplied in a convenient bulk package, ready for immediate integration into prototypes, production runs, or repair kits.

Usage

These PP bearing balls excel in environments where metal components would be prone to corrosion or where noise reduction is a priority. Typical uses include cosmetic roller bottles, fragrance sprayers, and laboratory floats, where a smooth, silent motion enhances user experience. They are also suitable for small‑scale industrial equipment such as drawer slides, miniature gear assemblies, and hobbyist robotics. Because PP does not rust, the balls can be employed in outdoor or humid settings, making them versatile for both indoor and outdoor projects. The G2 grade ensures that tolerances are tight enough for precision mechanisms while remaining affordable for large‑volume applications.

FAQ

What does the G2 grade indicate?

G2 grade is a classification for plastic bearing balls that defines a specific tolerance range. It means the balls have a diameter variation of ±0.001 mm, providing a balance between precision and cost suitable for most consumer and light‑industrial applications.

Can these balls be used in high‑temperature environments?

Polypropylene maintains its mechanical properties up to approximately 100 °C (212 °F). For applications that exceed this temperature, a different material such as nylon or metal would be more appropriate.

Are the balls compatible with lubricants?

Yes, the smooth PP surface can be used with light silicone or PTFE‑based lubricants to further reduce friction. Avoid petroleum‑based oils, as they can degrade the polymer over time.

How are the balls packaged?

The fifty balls are sealed in a resealable polybag that protects them from dust and moisture. The packaging includes the part number, material specification, and a brief usage guide.

What is the typical lifespan of these bearing balls?

When used within their design limits—proper load, speed, and temperature—the PP bearing balls can last for thousands of operating cycles. Their lifespan is primarily limited by wear from abrasive particles or excessive load, both of which can be mitigated with proper system design.
