72xx series angular contact ball bearings

Angular Contact Ball Bearings Sometimes referred to as "spindle bearings " angular contact bearings are used in machinery that requires high accuracy and durability Angular contact bearings have a much higher speed rating than radial bearings because of the nonstop contact of Angular contact ball bearings are often preloaded to enhance their rigidity and rotating performance For high-precision matched pair angular contact ball bearings of class 5 or higher which are used in machine tools and other precision equipment the standard preload is specified in three levels: light (L) medium (M) and heavy (H)

Angular Contact Ball Bearings

As previously mentioned angular contact bearings are usually mounted in a group of two or more opposed preloaded units with rigid or elastic spacers This can be done by matching up multiple single row bearings or by utilizing double row angular contact bearings which

High Precision Angular Contact Ball Bearings High precision angular contact ball bearings 70xx 72xx and 79xx series with 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)

Single row angular contact ball bearings which are intended for mounting in pairs (in sets) directly adjacent to each other are manufactured in the so-called universal design Figure 3 Figure 4 Figure 5 These bearings can be used in pairs in any arrangement without shims

Angular Contact Bearing Design Angular contact bearings have one ring shoulder removed this may be from the inner or outer ring This allows a larger ball complement than found in comparable deep groove bearings giving a greater load capacity Speed capacity of angular contact bearings is also greater than deep groove Barden angular contact

Double row angular contact ball bearings QIBR double row angular contact ball bearings († fig 4) correspond in design to two single row angular contact ball bearings arranged back-to-back but take up less axial space They can accommodate radial loads as well as axial loads in

Angular Contact Ball Bearings

Like other bearings angular contact ball bearings are also have lots of structures single row angular contact ball bearings can accommodate radial load and axial load in single direction 72xx and 73xx series •With A B C and AC contact angle •Double Row types with ball slot (32xx and 33xx Series) and without ball slot (52xx and 53xx

The axial load carrying capacity of angular contact ball bearings increases as the contact angle increases The contact angle is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane along which the combined load is transmitted from one raceway to another and a line perpendicular
