High Precision Angular Contact Ball Bearings (standard series) have a line connecting the contact points drawn in the radial direction which is called the contact angle. This contact angle makes the bearing suitable for accommodating radial loads, single direction axial loads and a combination of both, these bearings are generally used in pairs but can also be used in triplex sets, quadruplex sets or multiplex sets,
70xx, 72xx and 79xx series have three types of contact angle 15 degree (C), 25 degree (A5) and 30 degree (A), all come with two types of cage design either phenolic (TR) or polyamide (TYN),
