304 Stainless Steel Bearing Ball ZYsteelball G100 1.25in 2pcs

Description

Product Overview

These ZYsteelball 304 stainless steel bearing balls are engineered to meet G100 precision standards, offering a 1.25 inch (31.75 mm) diameter and a robust 2 piece pack. Their high grade stainless steel construction ensures corrosion resistance and long term durability, making them ideal for industrial machinery, scientific equipment, and precision engineering projects.

Each ball is manufactured using advanced cold‑drawing techniques that guarantee dimensional accuracy and surface finish within tight tolerances. The result is a smooth, low‑friction bearing surface that reduces wear on mating components and extends the service life of the entire assembly. The G100 grade designation reflects a rigorous quality control process, ensuring consistency across every batch.

Designed for ease of integration, the balls can be quickly installed into standard bearing housings, shafts, and rotary systems without the need for additional machining. Their compact size and balanced weight distribution help minimize vibration and noise, contributing to quieter operation in sensitive environments such as laboratories and clean rooms.

Usage

These precision balls are suited for a wide range of applications, from high‑speed spindles in CNC machines to low‑speed gearboxes in heavy‑duty equipment. Their corrosion‑resistant stainless steel composition makes them reliable in humid or chemically aggressive settings, such as food processing plants, pharmaceutical manufacturing, and marine equipment.

In scientific instrumentation, the balls provide stable rotational platforms for spectrometers, centrifuges, and optical devices where minute wobble can affect measurement accuracy. Their consistent geometry ensures repeatable performance, which is critical for experiments that demand high precision and repeatability.

For hobbyists and small‑scale manufacturers, the 2‑piece pack offers a cost‑effective solution for prototyping and custom builds. Whether you are assembling a custom robotic joint, a miniature wind turbine, or a DIY 3D printer extruder, these balls deliver the reliability and performance needed to bring your projects to life.

FAQ

What is the difference between G100 and other bearing ball grades?

G100 is a high‑precision grade that offers tighter tolerances on roundness and surface finish compared to standard grades. This results in smoother rotation, reduced vibration, and longer service life, especially in demanding industrial and scientific applications.

Can these balls be used in high‑temperature environments?

Yes, 304 stainless steel maintains its mechanical properties up to approximately 870 °C (1600 °F). For most industrial processes that operate below this temperature, the balls will retain their strength and corrosion resistance.

How do I determine the correct bearing size for my equipment?

Measure the bore diameter of the housing or shaft where the ball will be installed. Our 1.25 inch (31.75 mm) balls are compatible with standard metric and imperial bearing sizes. If you need assistance, our technical team can help you select the appropriate size based on your equipment specifications.

What warranty does ZYsteelball provide?

We offer a one‑year limited warranty covering material defects and manufacturing errors. If a ball fails due to a covered issue, we will replace it at no additional cost, ensuring uninterrupted operation for your projects.

Are there bulk purchasing discounts available?

Yes, we provide tiered pricing for larger orders. Contact our sales department for a customized quote and to discuss any special packaging or labeling requirements you may have.
