Product description of NSK Bearing 6906NR
NSK Bearing 6906NR, Single-Row With a Snap Ring Deep Groove Ball Bearings, NSK manufacture a full range of deep groove ball bearings. These bearings are the most common type and are used in a wide variety of applications. Pressed Steel Cages
NSK Bearing 6906NR Single-row deep groove ball bearings are the most common type of rolling bearings. Their use is very widespread. In addition to open type bearings, these bearings often have steel shields or rubber seals installed on one or both sides and are prelubricated with grease. Also, snap rings are sometimes used on the periphery. As to cages, pressed steel ones are the most common.
For big deep groove ball bearings, machined brass cages are used. Machined cages are also used for high speed applications. Deep groove ball bearings are versatile, self-retaining bearings. These bearings, which are of simple design, robust in operation and easy to maintain, are available in single row and double row designs and in open and sealed variants. Extra Small Ball Bearings and Miniature Ball Bearings Miniature and instrument ball bearings can be divided into two basic types, deep groove and angular contact. The first (deep groove) can be further divided into the following five classes depending on their design details: Standard type Flanged outer ring Extended inner ring Expanded type in which one ring has a radial thickness that is larger than normal compared with the bearing width. Thin section type in which both rings are extra thin in the radial direction. They can also be classified as: open, shielded, or sealed. Maximum-Type ball Bearings contain a larger number of balls than normal deep groove ball bearings because of filling slots in the inner and outer rings. Because of their filling slots, they are not suitable for applications with high axial loads. BL2 and BL3 types of bearings have boundary dimensions equal to those of single-row deep groove ball bearings of Series 62 and 63 respectively. Besides the open type, ZZ type shielded bearings are also available. When using these bearings, it is important for the filling slot in the outer ring to be outside of the loaded zone as much as possible. Their cages are pressed steel.
