Angular contact bearings from SKF handle radial and axial loads at the same time. The oblique contact raceways give the rigidity and precision that demanding equipment needs. MR Industrial Accessories supplies this line to maintenance and purchasing teams across the United States and in several Latin American countries.
Reading the designation helps you order the right bearing. The size code comes first, followed by the MPA suffix, which marks a variant with a machined brass cage guided by the inner or outer ring. Examples are 729106/100MPA and 729654/150MPA, both single row bearings with a 40° contact angle. Do not mix MPA up with other suffixes; it points to a defined cage and window arrangement built for high speeds and moderate loads.
Typical installations include centrifugal pumps, compressors, high-pressure fans, gearboxes and machine tool spindles, wherever combined loads appear. Plants in the food, petrochemical and metallurgical sectors rely on them for continuous process equipment, where precision and dependable running matter.
Selection depends on load size and direction, rotation speed and the surrounding conditions. Mounting calls for careful alignment and, in many cases, controlled axial adjustment. Grease or oil lubrication and good sealing against contaminants support service life, and internal clearance and preload should be checked against the application.
Interchange is possible with bearings from other makers that share the same dimensional designation and contact angle, but tolerances and internal design can differ, so compatibility is worth confirming before a replacement goes in. Send the complete designation and our team will advise.

Frequently asked questions
- What does the MPA suffix mean on an SKF bearing?
- MPA identifies a machined brass cage guided by the outer or inner ring, together with a 40° contact angle. It is common on single row bearings used for combined loads and high speeds.
- When should I choose an angular contact bearing over a radial one?
- If the application carries significant axial load along with radial load, an angular contact bearing fits better. For purely radial loads, a simple radial bearing may be enough. Speed and precision requirements also come into play.
- Can an SKF bearing be replaced by another brand?
- Yes, provided the main dimensions and the contact angle match. Tolerances and cage design can differ between manufacturers, so verify compatibility with a specialist before switching.
