Extra-thin section deep groove ball bearings from the FAG 618 series, identified by the 2RZ seal and Y suffix, handle radial and axial loads in both directions. They fit where radial space is tight and running accuracy matters. MR Industrial Accessories LLC supplies this line to maintenance and purchasing teams across the United States and Latin America.
Reading the code helps you order correctly. The base number, such as 61809, places the bearing in the 618 series, known for its extra-thin cross-section. The 2RZ marking means low-friction seals sit on both sides, keeping contaminants out and lubricant in. The trailing Y denotes a special execution, which can involve differences in internal clearance or heat treatment. Complete references like 61810-2RZ-Y and 61815-2RZ-Y follow this pattern.
These bearings appear in food processing, pharmaceutical production, robotics and precision equipment, where space is limited and cleanliness is important. They also serve machine tools, light conveying systems, medical instruments and optical devices. The sealed design suits dusty or moderately humid conditions as long as operating limits are respected.
Selection depends on the load to be carried, rotation speed and the surrounding environment. The 2RZ seal blocks particles well but is not intended for immersion. During mounting, align shaft and housing carefully and avoid impacts that could harm seals or raceways. Factory lubrication covers most uses; check the technical data before planning relubrication.
Other brands offer comparable extra-thin section deep groove ball bearings, though suffixes differ. A 2RS seal may match 2RZ in some cases, but tolerances and clearance must be verified before interchange. Confirm critical dimensions and operating conditions when substituting brands.

Frequently asked questions
- FAG 61811-2RZ-Y bearing: what are its dimensions?
- FAG 61811-2RZ-Y measures 55 mm across the bore and 72 mm across the outside diameter; its width is 9 mm (55 x 72 x 9 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 61811.
- What does the 2RZ suffix indicate on a FAG bearing?
- It means the bearing carries low-friction seals on both sides. These seals block contaminants and retain lubricant, which supports service life in tough conditions.
- Can the 618 series take axial loads?
- Yes, these deep groove ball bearings accommodate axial loads in both directions, though radial capacity is primary. For heavy axial duty, review other options or ask a specialist.
- How do I get a quote for these bearings?
- Send the complete part number, such as 61809-2RZ-Y, via WhatsApp or email. The team will respond promptly with the details you need.
