FAG 20224-K-MB-C3

FAG 20224-K-MB-C3 Spherical Roller Bearing

Description

The FAG 20224-K-MB-C3 is a premium spherical roller bearing designed to handle demanding conditions in various industrial applications. Its robust construction ensures high load-carrying capacity and the ability to compensate for angular misalignment. This makes it an ideal choice for machinery in sectors like mining, construction, and manufacturing. The tapered bore allows for secure mounting on cylindrical or tapered shafts using adapter or withdrawal sleeves.

FAQ

What do the suffixes K, MB, and C3 signify?

The suffix ‘K’ indicates a tapered bore with a taper of 1:12. ‘MB’ specifies a solid brass cage guided by the inner ring, which is suitable for high speeds and demanding conditions. ‘C3’ denotes a radial internal clearance that is greater than the ‘Normal’ (CN) clearance, often used in applications where there is a temperature differential between the inner and outer rings.

What is the proper procedure for mounting a bearing with a tapered bore?

Mounting a bearing with a tapered bore, like this 20224-K, typically involves an adapter sleeve or a hydraulic nut. The key is to achieve the correct reduction in radial internal clearance to ensure the proper interference fit on the shaft. This is usually measured using feeler gauges. Always refer to the FAG mounting instructions for precise values and procedures.

Is this FAG bearing directly interchangeable with an SKF bearing?

Yes, bearings from different manufacturers are often dimensionally interchangeable according to ISO standards. The direct equivalent for a FAG 20224-K-MB-C3 would be an SKF 22224 EK. While dimensions match, there can be slight differences in internal geometry or cage design, but for most applications, they are considered interchangeable.
