The SKF KM/P series self-aligning ball bearing is a self-aligning bearing with two rows of balls and a spherical raceway on the outer ring. It is designed to support moderate radial and axial loads, and to compensate for angular misalignment between shaft and housing. It is used in equipment where perfect alignment is not guaranteed, such as fans, pumps, conveyors and agricultural machinery. MR Accesorios Industriales supplies this series, with technical advice to choose the right variant.
The KM/P series designation is interpreted as follows: the base number (for example, 2219) identifies the size and dimension series; the KM suffix indicates that the bearing has a tapered bore (taper 1:12) for mounting on an adapter sleeve; the slash separates the P suffix which corresponds to a stamped steel window cage, ball-centered. In the example 2219 KM/P63, the 63 suffix indicates a special internal clearance, different from standard. Knowing these codes allows you to order the exact replacement.
This type of bearing is found in equipment where there is shaft flexing or alignment difficulties: industrial fans, centrifugal pumps, belt conveyors, vibrating screens, agricultural machinery and dryers. In Argentina, it is common in food plants, cement plants, steel mills and in the agro-industrial sector. Its self-aligning capability reduces premature wear and vibration, which extends the service life of the assembly and reduces unplanned downtime.
To select correctly, take into account the radial and axial load, the rotation speed and the environmental conditions. Sealing is key: if there is dust or humidity, choose variants with seals or protective plates. The internal clearance must be suitable for the working temperature; excessive or insufficient clearance shortens the bearing life. When mounting with a tapered bore, verify the tightening of the adapter sleeve and the clearance reduction with feeler gauges. Lubrication must be as indicated by the manufacturer and renewed at the recommended interval.
Regarding equivalences, self-aligning ball bearings from other brands with the same basic designation (for example, series 22) are usually dimensionally interchangeable, but may differ in internal clearance, cage or tolerances. Always compare the complete code, not just the base number. If your equipment has an SKF 2219 KM/P63 bearing, the safest approach is to order that exact code or consult for an equivalent alternative that meets the same specifications.

Frequently Asked Questions
- What are the dimensions of the SKF 2219 KM/P63 bearing?
- The SKF 2219 KM/P63 bearing has a 95 mm bore, a 170 mm outside diameter and a 43 mm width (95 x 170 x 43 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 2219.
- What does the KM suffix mean on an SKF bearing?
- The KM suffix indicates that the bearing has a tapered bore with 1:12 taper, designed to be mounted on an adapter sleeve. This facilitates mounting and dismounting on cylindrical shafts and allows the internal clearance to be adjusted by tightening the adapter sleeve.
- Is this bearing suitable for axial loads?
- Yes, self-aligning ball bearings support moderate axial loads in both directions, in addition to radial loads. However, for pure or very high axial loads, it is advisable to evaluate another type of bearing, such as angular contact or thrust bearings.
- How do I request a quote for an SKF 2219 KM/P63 bearing?
- Write to us on WhatsApp indicating the complete code 2219 KM/P63 and the quantity you need. You can also send a photo of the bearing inscription. We will quote you promptly.
