FAQ

What does the G28 grade signify for this precision ball?
The grade (G28) is a standard measure of a ball's quality, defined by standards like ISO 3290-1. G28 indicates a high level of precision, with very tight tolerances on diameter, sphericity (roundness), and surface roughness. This makes it suitable for applications requiring smooth and accurate motion.

What is the typical material for an AKN RB series ball and what are its properties?
AKN precision balls are typically made from high-carbon chrome alloy steel, such as 100Cr6 (AISI 52100). This material offers excellent hardness, wear resistance, and high load-bearing capacity after heat treatment, making it ideal for rolling bearing applications.

Can this ball be used as a replacement for a ball from a different manufacturer?
Yes, as long as the replacement ball has the exact same specifications: 28mm diameter, G28 grade, and a comparable material (like chrome steel). In precision applications, it is crucial to match these parameters to ensure proper fit, function, and longevity of the assembly.
