Decoding SKF 618/710 MA
- 618Series
- Deep groove ball bearings, 618 series. Series differ in outside diameter and width even when the bore is the same.
- /710Bore
- Bore: 710 mm.
- MASuffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
618/710 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description

SKF deep groove ball bearings in series MA use a machined brass cage and handle radial and axial loads in both directions. They suit high-speed, low-maintenance duty such as electric motors, pumps and industrial fans. MR Industrial Accessories LLC supplies this line to customers across the United States and several Latin American countries.
The code pairs the series number with the MA suffix, which stands for a machined brass cage centered on the rolling elements. Take 16048 MA: series 160, thin section, brass cage. Then 61830 MA: series 618, also thin section, with somewhat different dimensions. The MA suffix appears where greater strength and heat dissipation are needed compared with stamped steel cages.
Typical sectors include food, chemical, petrochemical and power generation. Large electric motors, centrifugal pumps, screw compressors and industrial ventilation equipment often run these bearings. High-speed capability and combined load capacity make them a fit for belt drives and direct couplings, as well as machine tools and continuous process equipment.
When selecting, review radial and axial load, rotation speed and environmental conditions. The brass cage resists temperature well and permits higher speeds than polyamide cages. Correct shaft-to-housing alignment and adequate lubrication, grease or oil as the application requires, are essential. Sealing depends on contamination levels; in dirty environments, add extra protection.
For equivalences, SKF deep groove ball bearings interchange with other brands that follow the same standardized dimensions. The MA suffix is SKF-specific for brass cage, though other makers may use similar designations. Always confirm the complete code and tolerances before replacing a bearing. Interchangeability rests on main dimensions and cage type, not on the manufacturer's prefix.

Frequently asked questions
- SKF 618/710 MA bearing: what are its dimensions?
- SKF 618/710 MA measures 710 mm across the bore and 870 mm across the outside diameter; its width is 74 mm (710 x 870 x 74 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 618/710.
- What does the MA suffix mean on an SKF bearing?
- It identifies a machined brass cage centered on the rolling elements. This cage handles higher temperatures and speeds than stamped steel or polyamide cages.
- Can these bearings be replaced with another brand?
- Yes, if the main dimensions and cage type match. The MA suffix is SKF-specific, but other brands may offer brass-cage equivalents. Verify the full code and tolerances first.
- Where are series MA bearings typically used?
- Electric motors, pumps, compressors, industrial fans and machine tools. They suit high speeds and combined loads where low friction and long service life matter.
