28.565mm G28 1 Inch Metal Ball , High Chrome Steel Bearing Balls

28.565mm(1-1/8 Inch),G28, High Chrome Steel Balls For Also Ball Bearing

Introduction

GCr15 bearing steel is a kind of high carbon chromium bearing steel with low alloy content, good performance and the most versatile. After quenching and tempering, it has high hardness, uniformity, good wear resistance and high contact fatigue performance. The steel has the characteristics of moderate plasticity, low cutting performance, poor welding performance, high sensitivity to white spots and temper brittleness. GCr15 bearing steel, containing c0.95-1.05, Mn0.25-0.45, Si0.15-0.35.

After precision cleaning and oiling, and before the sample balls in the packaging batch, they should be sent to the final audit to check the surface roughness, roundness, waviness in a precise testing room according to the designated control plan. Variation in batch size and hardness. Once all requirements are met, a test certificate will be prepared for the customer. 

We produce chrome steel balls and stainless steel balls, and more balls of various sizes. With a manufacturing plant equipped with the most advanced equipment, we have the ability to meet all your needs

Application

Found primarily in ball bearing designs and a variety of demanding industrial applications. A vacuum-degassed AISI E52100 chrome steel is used to obtain a superior ball with a fine surface finish, through-hardness and high load capacity. Also available in consumable electrode vacuum melt material.

Often the ideal design solution is not about finding the fastest, sturdiest, most accurate or even the least expensive option. Rather, the ideal solution is the optimal balance of performance, life and cost.

Specification

If your application requires customized balls, please send us your specifications, we are happy to meet them.

Ball Diameter 

1. Nominal Ball Diameter: The diameter value that is used for the purpose of general identification of a ball size, e.g., 1/4“, 6mm, etc.

2. Ball Gauge:For the specified small quantity, the average batch diameter should be different from the nominal diameter, which is one of a series of determined quantities. The combination of ball gauge, ball grade and nominal ball diameter should be regarded as the most accurate ball size specification used by customers for ordering purposes.

3. Specific Diameter: The amount by which the lot mean diameter differs from the nominal diameter, accurate to the container marking increment for that grade. The specific diameter should be marked on the unit container.

4. Container Marking Increment: The standard unit steps in micrometers or in millionths of an inch, used to express the specific diameter.
