Precision Balls
Atlas Ball and Bearing Co. Ltd. is a stockist/distributor who is capable of supplying loose balls in nearly every variation of grade and material available.
We are also able to offer bespoke ball manufacturing from customer/free issue supplied material. This offers the same process controls and traceability but using a customers own material. For further details email us at MAIL or phone us on +44 (0) 1922 710515
We maintain an extensive stock of product size variation from 0.2mm diameter up to 150mm diameter.
Our experienced sales and technical staff are well versed in the principal grading systems used throughout the world. If, however, you wish to order using a specific grading system, a specific drawing or specification, we will be only too happy to discuss your particular requirements.
Product can be packed in customer specific quantities and to specific packaging requirements.
Everyday life would be very different without
the use of balls they are in almost every domestic appliance, every bicycle,
motorbike, car, train and aircraft. Every time you wash your hands and
use a soap dispenser, it is the ball that enables you to get a measured
amount of soap.
We are able to handle large one off bulk deliveries as well as call
off/scheduled orders.
In order to simplify the purchase of balls we have devised our own grading system based on ISO and ABMA standards.

Useful Terms and Definitions used to describe Precision Balls.
Nominal Ball Diameter - The diameter value that is used for the general identification of a ball size.
Single Ball Diameter - The distance between two parallel planes tangential to the actual ball surface.
Diameter Tolerance per Batch - The allowed difference between the smallest measured ball diameter and the largest ball diameter within the same batch or lot.
Batch or Lot - A definite quantity of balls manufactured under conditions presumed to be uniform and which is considered an entity.
Sphericity - A measure of roundness expressed as the difference between the measured roundness of a ball and a perfectly round ball.
Surface Finish or Roughness - A measure of the texture of a surface. It is quantified by the vertical deviations of the actual surface from it's ideal form, if these deviations are large the surface is rough; if they are small the surface is smooth.
Hardness - A measure of resistance to penetration as determined by specific methods, usually Rockwell or Vickers Hardness.
