Angular Contact Ball B. FAG 3322 -M

The FAG 3322-M angular contact ball bearing, with main dimensions of 110 × 240 × 92.1 mm, can accommodate high radial forces as well as axial forces on both sides.

The 3322-M angular contact ball bearing is a double-row rolling bearing manufactured by FAG Wälzlager. Functionally, its design corresponds to two single-row angular contact ball bearings in an O-arrangement, but requires less installation space in the axial direction. Manufactured from standard rolling-element bearing steel 100Cr6, this component is characterised by high dimensional stability. Designed as an open bearing, this model can be integrated directly into oil- or grease-lubricated machine housings to perform demanding guidance tasks.

What loads can the 3322-M double-row angular contact ball bearing withstand?

Design engineers primarily use this rolling bearing where high radial forces and alternating axial loads in both directions act simultaneously on the shaft. Thanks to its two rows of balls, the bearing effectively counteracts tilting moments. Typical applications include shaft mountings in general mechanical engineering subject to combined loads. As it complies with tolerance class P0/PN (corresponding to ABEC 1), the bearing fits into standardised housing seats and ensures smooth running under defined operating conditions.

What are the features of the brass cage in the 3322-M angular contact ball bearing?

The suffix ‘-M’ indicates a brass cage, which guides the rolling elements precisely. Compared with cages made of sheet steel or plastic, brass is suitable for environments subject to vibrations, accelerations and thermal stresses within a temperature range of –20 to +200 degrees Celsius. The open design without seals requires a clean installation environment and a supply of lubricant via the housing. Normal radial bearing clearance ensures that the rolling elements can roll freely within the specified operating temperature range.
