Self-aligning ball bearings

The self-aligning ball bearing has two rows of balls and a spherical raceway on the outer ring. This geometry allows it to self-align and compensate for misalignment between shaft and housing or shaft deflection. It has low friction and allows good speeds, with moderate load capacity. It is chosen when housings are not perfectly aligned or the shaft deflects.

In series 12 and 13, and in the wider 22 and 23, the last two digits multiplied by 5 give the bore from 04: 1204 would be 20 mm. With 00 the bore is 10 mm and with 01, 12 mm, as in 1200S and 1201S from NTN. Series 13 and 23, such as 1300S and 2300S, have a larger outside diameter than 12 and 22. The suffixes TN9 in SKF (11204 TN9) and TVH in FAG (11204-TVH) indicate a polyamide cage. Short designations such as 108, 126 or 135 correspond to small bearings with a bore of a few millimeters.

They are used in conveyors, fans, pumps, belt drives and process equipment in general. If the radial load is high or shock is strong, a spherical roller bearing should be considered.

We work with self-aligning ball bearings from SKF, FAG, NSK and NTN. Send us the complete part number or the shaft diameter, outside diameter and width via WhatsApp or email, and we will quote it promptly. If you have the part number from another brand, we will indicate the equivalent.
