Double row deep groove ball bearings feature higher load ratings than single row bearings, but are very sensitive to misalignments. This series have the latest design (suffixed 'B') without filling slots.Fitted with polyamide cages (suffixed 'TN') as standard, pressed steel cages are also available. However, some bearings may have filling slots that limit the ability to support thrust loads.
Due to their versatility, the ball bearings are the most popular of all anti-friction bearing types. They are available in a broad range of sizes, from miniature ball bearings with outside diameters of less than 9mm, to extra-large bearings that exceed 800mm in diameter. These bearings are also available in a wide variety of shield, seal and snap-ring arrangements.

Such miniature bearings can be made with high quality standards and EMQ noise levels.
These products are widely used in miniature motors, washing machines, mines, electrical machines, automobiles, and other mechanical equipment and electrical household appliances.
Thises deep groove bearings have full shoulders on both sides of the raceways of the inner and outer rings. The outer rings of Series FR bearings are flanged to provide accurate positioning surfaces. These bearings are easily installed in through-bored holes, eliminating the need for housing shoulders or shoulder rings. They are manufactured to inch dimensions. They can accept radial loads, thrust loads in either direction, or combinations of loads.
