Part Number MMC205K, Fafnir® Spindle Deep Groove Ball Bearings (9100K, 200K, 300K)
larger image
Radial ball bearings consist of an inner and outer ring with a cage containing a complement of precision balls. The standard Conrad-type bearing has a deep-groove construction capable of handling radial and axial loads from either direction in versatile designs that permit relatively high-speed operation.
In addition to standard single-row deep groove bearings, Timken offers special designs, including a maximum capacity series and an extra large (XLS) radial series bearing.
Size range: 3 mm - 600 mm (0.12 in. - 23.62 in.) bore
