Decoding SKF 2219 KM/P63
- 22Series
- Self-aligning ball bearings, 22 series. Series differ in outside diameter and width even when the bore is the same.
- 19Bore
- Bore 95 mm (19 × 5).
- KM/P63Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
2219 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 2219 KM/P63 measures 95 mm across the bore and 170 mm across the outside diameter; its width is 43 mm (95 x 170 x 43 mm).

The SKF KM/P series self-aligning ball bearing features two rows of balls and a spherical raceway in the outer ring, allowing it to handle moderate radial and axial loads while compensating for angular misalignment between shaft and housing. It is commonly found in fans, pumps, conveyors, and agricultural machinery, where perfect alignment is difficult to maintain. MR Industrial Accessories supplies this series and provides technical guidance to select the correct variant.
The code structure helps you identify the exact bearing. The base number, such as 2219, defines the size and dimension series. The KM suffix means the bearing has a tapered bore (1:12) for mounting on an adapter sleeve. The slash separates the P suffix, which indicates a stamped steel window cage, ball-centered. In a code like 2219 KM/P63, the 63 denotes a special internal clearance, different from standard. Understanding these elements ensures you order the right replacement.
These bearings are used in equipment where shaft flexing or alignment issues occur: industrial fans, centrifugal pumps, belt conveyors, vibrating screens, agricultural machinery, and dryers. Their self-aligning capability helps reduce premature wear and vibration, which can extend the service life of the assembly and lower unplanned downtime.
Selection depends on radial and axial load, rotation speed, and environmental conditions. Sealing is critical: in dusty or humid environments, choose variants with seals or protective plates. Internal clearance must suit the operating temperature; too much or too little clearance shortens bearing life. When mounting a tapered bore, verify adapter sleeve tightening and clearance reduction with feeler gauges. Follow the manufacturer's lubrication instructions and renewal intervals.
For equivalences, self-aligning ball bearings from other brands with the same basic designation (e.g., series 22) are often dimensionally interchangeable, but may differ in internal clearance, cage, or tolerances. Always compare the complete code, not just the base number. If your equipment uses an SKF 2219 KM/P63, the safest choice is to order that exact code or consult for an equivalent that meets the same specifications.

Frequently asked questions
- SKF 2219 KM/P63 bearing: what are its dimensions?
- SKF 2219 KM/P63 measures 95 mm across the bore and 170 mm across the outside diameter; its width is 43 mm (95 x 170 x 43 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 2219.
- What does the KM suffix mean on an SKF bearing?
- The KM suffix indicates a tapered bore with 1:12 taper, designed for mounting on an adapter sleeve. This simplifies mounting and dismounting on cylindrical shafts and allows internal clearance adjustment by tightening the sleeve.
- Is this bearing suitable for axial loads?
- Yes, self-aligning ball bearings support moderate axial loads in both directions, along with radial loads. For pure or very high axial loads, consider other bearing types such as angular contact or thrust bearings.
- How do I request a quote for an SKF 2219 KM/P63 bearing?
- Send us a WhatsApp message with the complete code 2219 KM/P63 and the quantity you need. You can also send a photo of the bearing inscription. We will respond promptly with a quote.
