Self-Aligning Ball Bearings supplier in Mumbai

Two rows of balls on a spherical outer raceway, for shafts that bend or housings that do not line up.

Self-aligning ball bearings have two rows of balls running on one spherical raceway in the outer ring. Because of that, the inner ring and shaft can tilt a little relative to the housing without harming the bearing, which helps where a shaft bends under load or two housings are not perfectly in line. They carry light to medium radial loads and some axial load in either direction. For heavy loads, a spherical roller bearing is the stronger choice.

Self-aligning ball bearings in the 12, 13, 22 and 23 series, with cylindrical or tapered bores. SKF and FAG.

How to choose self-aligning ball bearings

Reading the number

Self-aligning ball bearings are numbered in the 12, 13, 22 and 23 series. The last two digits give the bore code: multiply by 5 for the bore in mm, so a 1205 has a 25 mm bore. The 22 and 23 series are wider than the 12 and 13 for the same bore.

Letters after the number

K means a tapered bore (1:12), for mounting on an adapter sleeve. TN9 is a glass-fibre reinforced polyamide cage, and the E before it marks an optimised internal design, as in 1205 ETN9. Makers use their own letters for some designs, so quote the whole number.

When to choose a spherical roller bearing

A self-aligning ball bearing suits light to medium loads. If the load is heavy or there are shocks, a spherical roller bearing allows the same tilt with much higher load capacity.

Buying tips for self-aligning ball bearings

  • Match the full designation: the series digits, the bore and the letters after the number, such as K for a tapered bore.
  • A tapered bore (K) is normally mounted on an adapter sleeve, which makes fitting on long plain shafts easier.
  • The permitted tilt is small. If the misalignment is large, or the load heavy, ask us about a spherical roller bearing.

Questions

Self-Aligning Ball Bearings: frequently asked

What is the difference between a self-aligning ball bearing and a spherical roller bearing?

Both let the shaft tilt a little. A self-aligning ball bearing uses two rows of balls and carries lighter loads. A spherical roller bearing uses two rows of rollers and carries much heavier loads.

What does K mean in a self-aligning ball bearing number?

K means the bore is tapered (1:12) instead of cylindrical. The bearing is normally mounted on an adapter sleeve.
