Product description of SKF Bearing 3315 A

SKF Bearing 3315 A, it belongs to SKF Bearing > Rolling bearings > Ball bearings > Angular contact ball bearings > double row, and we have related type you may also like SKF Bearing 3315 A-2Z.

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 3315 A,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.

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)
SKF Bearing 3315 A, Features and benefits
High load carrying capacity
The lower shoulder enables a large number of balls to be incorporated in the bearing, giving it a relatively high load carrying capacity.

Good running properties
Rapid accelerations and declarations are possible.
Easy mounting of universally match-able bearings
No adjustment is needed for correct internal clearance or preload.
For bearings arranged in pairs, the limiting speed should be reduced to approximately 80% of the value quoted for a single bearing.

The speed ratings in the product table indicate:
the reference speed, which enables a quick assessment of the speed capabilities from a thermal frame of reference
the limiting speed, which is a mechanical limit that should not be exceeded unless the bearing design and the application are adapted for higher speeds

SKF Bearing 3315 A, Single row angular contact ball bearings are particularly suitable where:
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.
