Decoding SKF 61810-2RZ
- 618Series
- Deep groove ball bearings, 618 series. Series differ in outside diameter and width even when the bore is the same.
- 10Bore
- Bore 50 mm (10 × 5).
- 2RZSuffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
61810 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 61810-2RZ measures 50 mm across the bore and 65 mm across the outside diameter; its width is 7 mm (50 x 65 x 7 mm).

For rotating equipment that needs dependable radial and axial support, the SKF 2RZ deep groove ball bearing is a common choice. Its single-row ball construction runs with low friction, and the 2RZ designation means both sides carry low-friction seals that keep lubricant in and contaminants out. MR Industrial Accessories supplies this line to maintenance and purchasing teams across the United States and Latin America.
Reading the code helps you match a bearing to the application. The base number identifies series and size, and the 2RZ suffix tells you the bearing is sealed on both sides. In the 60 series, which is extra light, an example is 6006-2RZ; the 62 series is light, as in 6206-2RZ; and the 63 series is medium, as in 6306-2RZ. Prefixes such as 618 belong to the 68 series, ultra light. Not every code in a catalog follows these series, so confirm the number before ordering.
These bearings appear in electric motors, pumps, fans, conveyors and machine tools. Because they handle combined loads and adapt to many arrangements, they are found in food processing, textile, automotive and metallurgical plants. The sealed design suits dusty areas or moderate humidity where an extra barrier is useful without giving up speed.
When selecting a bearing, review radial and axial load, rotation speed and the surrounding environment. The 2RZ seal runs with low friction and provides good protection, but for direct liquid exposure or fine particles, consider a contact seal instead. During installation, keep shaft and housing aligned and avoid impacts that could damage the seals. Factory lubrication covers most applications and simplifies maintenance.
SKF 2RZ bearings can be interchanged with other brands that use the same international designation. Tolerances and internal clearance can differ between manufacturers, so verify them before substituting. MR Industrial Accessories can suggest equivalents and help you choose based on your equipment.

Frequently asked questions
- SKF 61810-2RZ bearing: what are its dimensions?
- SKF 61810-2RZ measures 50 mm across the bore and 65 mm across the outside diameter; its width is 7 mm (50 x 65 x 7 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 61810.
- What does the 2RZ suffix mean on an SKF bearing?
- It indicates low-friction seals on both sides. These seals block contaminants and hold lubricant in place, making the bearing suitable for moderate speeds and dusty conditions.
- How do I decide between a 2RZ and a 2RS bearing?
- The 2RZ seal is low friction and supports higher speeds, while 2RS uses contact seals for better sealing but more friction. Base the choice on speed and contamination levels.
- Are SKF 2RZ bearings lubricated at the factory?
- Yes, they normally arrive lubricated for life with quality grease. Most applications do not require relubrication, which reduces maintenance work.
