Download the current general catalogue EN

The double row self-aligning ball bearings have two rows of balls and a spherical raceway on the outer ring. Certain misalignment of the inner ring referring to the outer ring around the bearing centre will work independently of the bearing operation.

The bearings are used for applications which presume certain bore misalignment in the bearing housings or deflaction and oscillation of the shaft at long mutual distance of the bearing. The bearings are non-separable. With respect to their small contact angle and the imperfect conformity of the balls to the raceways, they are not recommended for carrying larger axial forces. The bearings are manufactured with cylindrical or tapered bores.

Boundary dimensions

The boundary dimensions of the double row self-aligning ball bearings indicated in the dimension tables correspond to the international dimensional pian ISO 15. Adapter sleeve dimension correspond to dimension according to ISO 113.

Designation

The designation of the bearings in the basic design and in the modification with a tapered bore (K) is indicated in the dimension tables. Bearing differences from the basic design are indicated by additional symbols.

Tapered bore

The double row self-aligning ball bearings are manufactured with a cylindrical or tapered bore (K), taper 1:12 as indicated in the dimension tables.

The bearings are fixed on cylindrical shafts by adapter sleeves. The designation of the adapter sleeves belonging to individual bearings is stated in the table section of this publication.

Cages

The double row self-aligning ball bearings have cages made by pressing a steel sheet which are not designated. Bearings of the 12, 13 Series have a single cage. Bearings of the 22, 23 Series have a two-piece cage. For special applications, bearings with polyamide cages which are marked TNGH can be manufactured. The delivery of the bearings with this cage must be negotiated in advance.

Precision

The double row self-aligning ball bearings are commonly manufactured within the normal tolerance class P0 (the symbol P0 is not indicated). For speciál applications requiring high accuracy or in operation under high speed, the bearings can be supplied in the higher tolerance class P6.

Radial Clearance

The commonly manufactured double row self-aligning ball bearings have a normal radial clearance which is not indicated. For special applications, bearings with reduced (C2) or increased (C3, C4) radial clearances can be supplied.

Misalignment

The double row self-aligning ball bearings can be tilted out of the central position without affecting the correct bearing operation. The permissible misalignment values are stated in the following chart.

Bearing Type	Permissible Misalignment
13, 23	3°
12, 22	2°30´

Radial Equivalent Dynamic Load

Pr = Fr + Y1 Fa for Fa/Fr ≤ e

Pr = 0,65 Fr + Y2 Fa for Fa/Fr > e

The factor values e, Y1 and Y2 for individual bearings, are indicated in the dimension tables.

Radial Equivalent Static Load

Por = Fr + Yo Fa

The factor values Y0 for individual bearings are indicated in the dimension tables.
