The SKF deep groove ball bearing of the MA/C4S1 series is a precision component designed to support radial and axial loads in both directions. Its single-row construction with machined brass cage and C4 internal clearance makes it suitable for applications requiring high speed and tolerance to thermal expansion. MR Accesorios Industriales supplies this line as a brand for the Argentine industrial market.
The designation of this series is interpreted from its letters and suffixes. MA indicates a machined brass cage, ball-centered, a robust solution for severe service. C4 indicates an internal radial clearance greater than standard, intended for fits with tight interference or significant thermal gradients. S1 identifies a special heat treatment that stabilizes the ring for high operating temperatures. The example 6228 MA/C4S1 combines these characteristics in a medium-section bearing.
This type of bearing is used in rotating equipment in Argentine industry such as centrifugal pumps, induced draft fans, gearboxes and machine tools. Its ability to run at high speeds and support combined loads makes it common in large electric motors and reciprocating compressors. It also appears in railway applications and in the cement industry, where service conditions demand durable and reliable components.
For correct selection, take into account the internal clearance: a C4 requires a mounting fit that compensates for differential expansion between inner and outer rings. The MA cage allows higher speeds than a polyamide one, but requires adequate lubrication. Check alignment between housings and avoid excessive pure axial loads. Sealing will depend on the environment: in the presence of dust or moisture, choose additional seals or bearings with protective shields.
Regarding equivalences, deep groove ball bearings with brass cage and C4 clearance from other brands can be interchanged if main dimensions, tolerances and clearance match. However, lubrication and mounting conditions are critical to performance. Always consult the original manufacturer's specifications and verify that the replacement meets the load and speed requirements of your equipment.

Frequently Asked Questions
- What are the dimensions of the SKF 6228 MA/C4S1 bearing?
- The SKF 6228 MA/C4S1 bearing has a 140 mm bore, a 250 mm outside diameter and a 42 mm width (140 x 250 x 42 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 6228.
- What does the C4 suffix mean in this bearing?
- The C4 suffix indicates an internal radial clearance greater than standard. It is used in assemblies with pronounced interference fits or when there are thermal differences between inner and outer rings, to prevent the bearing from becoming preloaded.
- Is the MA cage suitable for high speeds?
- Yes, the MA machined brass cage is suitable for high speeds and severe loads. Its ball-centered design reduces friction and improves heat dissipation, although it requires correct lubrication for prolonged operation.
- Can I replace this bearing with one from another brand?
- You can replace it if the alternative bearing has the same main dimensions, tolerances and internal clearance. It is essential to verify lubrication and mounting conditions. Consult us with the original code and we will help you find the right equivalent.
