1. Self-aligning roller bearings with cylindrical bores can be divided into CA and C versions according to inner rings (with or without ribs) and cages. The CA version self-aligning roller bearings with solid cages with double claws which are made of brass or carbon steel ,have two small ribs on two ends of the inner ring, no ribs at the middle. CA version is mostly used on large size and extra large size bearings. The C version Self-aligning roller bearings with pressed steel cage dont have rib on inner ring, and have movable central rib in the middle .There rollers are guided by themselves. The rating load of these bearings are increased due to the long length of rollers, they have high limit rotational speed and lower friction consumption.

2. Self- aligning roller bearings with tapered bores. The features of self-aligning roller bearings with tapered bores are the same as Self-aligning roller bearings with cylindrical bore. The difference is that their inner bore is tapered, normally the tapered is 1:12 and is denoted with the suffix K. the tapered 1:30 is applicable for 240 and 241 series, denoted with suffix K30. Self- aligning roller bearings with tapered bore can be mounted directly on conical shaft necks by nuts, and also can be fixed on shafts with cylindrical bore by adapter sleeve or withdrawal sleeve.

Applications: Self- aligning roller bearings are mainly used in various kinds of machinery, paper machinery, textile machinery and electrical machinery. Theyre widely used in mechanical industry.
