SKF deep groove ball bearings of series MA are precision components with machined brass cage, designed to withstand radial and axial loads in both directions. They are used in applications requiring high speed and low maintenance, such as electric motors, pumps and industrial fans. At MR Accesorios Industriales we sell this line.
The designation of these bearings combines the series number with the suffix MA, which indicates a machined brass cage, centered on the rolling elements. For example, 16048 MA corresponds to a bearing of series 160, thin section, with brass cage. Similarly, 61830 MA belongs to series 618, also thin section, but with somewhat different dimensions. The MA suffix is common in applications requiring greater strength and heat dissipation than stamped steel cages.
These bearings are used in industries such as food, chemical, petrochemical and power generation. In Argentina, it is common to find them in large electric motors, centrifugal pumps, screw compressors and industrial ventilation equipment. Their ability to operate at high speeds and withstand combined loads makes them suitable for belt drives and direct couplings. They are also used in machine tools and continuous process equipment.
To select the right bearing, take into account radial and axial load, rotation speed and environmental conditions. The brass cage offers good temperature resistance and allows higher speeds than polyamide cages. It is essential to ensure correct alignment between shaft and housing, and adequate lubrication, either with grease or oil, depending on the application. Sealing will depend on the contamination present; in dirty environments, additional protection is recommended.
Regarding equivalences, SKF deep groove ball bearings can be interchanged with those of other brands that follow the same standardized dimensions. The MA suffix is specific to SKF for brass cage, but other brands may use similar designations. Always verify the complete code and tolerances before replacing a bearing. Interchangeability is given by the main dimensions and the type of cage, not by the manufacturer's prefix.

Frequently Asked Questions
- What are the dimensions of the SKF 61968 MA bearing?
- The SKF 61968 MA bearing has a 340 mm bore, a 460 mm outside diameter and a 56 mm width (340 x 460 x 56 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 61968.
- What does the suffix MA mean in an SKF bearing?
- The suffix MA indicates that the bearing has a machined brass cage, centered on the rolling elements. This cage is more resistant to high temperatures and allows higher speeds than stamped steel or polyamide cages.
- Are these bearings interchangeable with other brands?
- Yes, provided the main dimensions and the type of cage match. The MA suffix is specific to SKF, but other brands may offer equivalent bearings with brass cage. Always verify the complete code and tolerances.
- What typical applications do bearings of series MA have?
- They are used in electric motors, pumps, compressors, industrial fans and machine tools. They are suitable for high speeds and combined loads, especially where low friction and long service life are required.
