7mm Precision Balls Kozelo Nylon PA66 Bearing Balls 10pcs Pack

Description

Product Overview

The Kozelo 7mm precision balls are engineered from premium PA66 nylon, a high‑performance engineering polymer known for its superior wear resistance, dimensional stability, and ability to withstand elevated temperatures. By selecting PA66 over traditional POM, the balls achieve a balance of toughness and rigidity that translates into longer service life in demanding environments.

Each ball measures exactly 7 mm in diameter and is supplied in a convenient pack of ten, allowing engineers, hobbyists, and laboratory technicians to stock essential components for a variety of low‑load bearing applications. The surface finish is tightly controlled to ensure smooth rotation, minimizing friction and reducing the need for additional lubrication in many use cases.

Beyond the core material advantages, the design incorporates a uniform spherical geometry that promotes even load distribution across contact points. This characteristic is especially valuable in precision devices where even minute variations can affect performance, such as flow meters, carburetors, and fluid level indicators.

Manufactured by Kozelo, a brand recognized for its commitment to quality in industrial and scientific components, these balls meet stringent quality control standards. The product carries the model number klf230627zz000009 and has been available since August 31 2023, quickly gaining positive feedback for its reliability and consistency.

Usage

These 7mm nylon precision balls excel in low‑load bearing scenarios where traditional metal bearings would be over‑engineered. Typical installations include valve stems, check valves, and specialty valves where the reduced weight of nylon contributes to smoother operation and lower inertia.

In fluid handling systems, the balls serve as rolling elements in flow meters and level sensors, providing accurate measurement without contaminating the fluid stream. Their chemical resistance ensures compatibility with a wide range of liquids, from water to mild solvents.

Laboratory environments benefit from the balls’ dielectric properties, making them suitable for use in electro‑static sensitive equipment, such as analytical balances and precision positioning stages. Their high‑temperature tolerance also allows them to function reliably in heated chambers up to 150 °C.

FAQ

What is the recommended temperature range for these PA66 nylon balls?

The PA66 nylon material is rated for continuous operation from -40 °C up to 150 °C. Within this range the balls retain their mechanical properties, ensuring reliable performance in most industrial and laboratory settings.

Can these balls be used in high‑speed rotating applications?

Yes, the smooth spherical geometry and low friction surface allow the balls to operate at moderate speeds typical of low‑load bearings. For very high‑speed applications, metal or ceramic alternatives may be more appropriate.

Are the balls compatible with chemical solvents?

PA66 nylon exhibits good resistance to many common solvents, including water, alcohols, and mild acids. However, it is not recommended for use with strong acids, strong bases, or aggressive organic solvents such as acetone or benzene.

How do I verify the ball diameter before installation?

Use a calibrated micrometer or a precision gauge block set to measure the ball diameter. The tolerance is ±0.01 mm, so a measurement within 6.99 mm to 7.01 mm confirms compliance with specifications.

What is the packaging format and how many balls are included per pack?

Each package contains ten individual 7 mm precision balls, securely sealed in a compact cardboard box. The packaging dimensions are 3.54 × 2.36 × 0.59 inches, weighing approximately 0.48 ounces, making it easy to store and handle.
