ball bearing, magneto bearing, miniature bearing

Deep groove ball bearings are particularly versatile. They are suitable for high and very high speeds, accommodate radial and axial loads in both directions and require little maintenance. Because deep groove ball bearings are the most widely used bearing type, they are available from BHR in many designs, variants and sizes. They are as follows:

Single-Row Deep Groove Ball Bearings

Pressed Steel Cages

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.

6000 Series - Extra Light Ball Bearings – Ideal for limited space applications

6200 Series - Light Series Ball Bearings – Balanced between space and load capacity

6300 Series - Medium Series Ball Bearings – Ideal for heavier load capacity applications

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

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.

Magneto Bearings

The inner groove of magneto bearings is a little shallower than that of deep groove bearings. Since the outer ring has a shoulder on only one side, the outer ring may be removed. This is often advantageous for mounting. In general, two such bearings are used in duplex pairs. Magneto bearings are small bearings with a bore diameter of 4 to 20 mm and are mainly used for small magnetos, gyroscopes, instruments, etc. Pressed brass cages are generally used.

In addition to the bearings presented in this section, deep groove ball bearings for special applications can also be supplied. These bearings include:

Sensor bearing units

High temperature bearings and bearing units

Bearings with Solid Oil

INSOCOAT bearings

Hybrid bearings

NoWear coated bearings

Polymer ball bearings
