Product description of SKF Bearing 7308 BEGBP

SKF Bearing 7308 BEGBP, SKF single row angular contact ball bearings can accommodate axial loads in one direction only. This type of bearing is typically adjusted against a second bearing. Their bearing rings have an upper and a lower shoulder and are non-separable.Angular contact ball bearings have inner and outer ring raceways that are displaced relative to each other in the direction of the bearing axis. This means that these bearings are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads.

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 to the bearing axis SKF Bearing 7308 BEGBP, Single row angular contact ball bearings are particularly suitable

bearing arrangements must support combined loads moderate to high axial loads are present on one side rigid axial guidance is required the bearing arrangement must be axially clearance-free or preload-ed high speeds are required under higher radial and axial loads.

SKF Bearing 7308 BEGBP, The SKF standard assortment of single row angular contact ball bearings (fig. 1) includes:
bearings in the 72 B(E) and 73 B(E) series with 40° contact angle
some sizes in the 70 B series
sealed bearings:
in series 72 B(E) (15 ≤ d ≤ 55 mm)
in series 73 B(E) (12 ≤ d ≤ 50 mm)
bearings in the 72 AC series with 25° contact angle (15 ≤ d ≤ 70 mm)
bearings in the 73 AC series with 25° contact angle (17 ≤ d ≤ 70 mm)
some large size bearings with a flanged outer ring
SKF inch bearings (ALS and AMS series)
are available with 25° and 40° contact angles are intended to be used in sets have ring widths and standouts manufactured to tight tolerances can also be used in place of basic design bearings for arrangements with single bearings, as they typically have higher precision, and increased load carrying capacity and speed capability When two bearings are mounted immediately adjacent to each other, a given internal clearance or preload or an even load distribution between the two bearings is obtained without the use of shims or similar devices.
Bearings for universal matching are identified by the following suffixes:
CA, CB, CC or G for internal clearance
GA, GB or GC for preload
When ordering, indicate the number of individual bearings required and not the number of sets.
