Deep Groove Ball Bearings

TG 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.

Design Attributes :

Newly developed seals (double-lip labyrinth RS2): Improved protection against contamination with low friction, better grease retentionNew, special low-noise lubricant: Lower starting torque over a wide range of temperatures

Superior surface finish on raceways: Reduced friction, lower operating temperature

Closer grade balls: More uniform running and lower noise

Reduced running noise: Through 100% noise testing with stringent limit values

Technical data of the lubricant

Typical applications:

electrical motors

general machinery

industrial gearboxes


agricultural machinery

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.

Extra Small Ball Bearings and Miniature Ball Bearings

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.

Deep Groove Ball Bearings
Double row cylindrical roller bearings full performance characteristics

TWB SL04 series double row full complement cylindrical roller bearing mainly used to sheave, as it has large radius load capacity and shock-proof ability as well as axial load capacity in both directions.

Comprising one outer ring and two inner rings, the bearing is assembled as a unit by an internal locking structure. The width of the outer ring is less than total width of two inner rings by 1 mm, two snap rings are fitted on the outer ring, oil grooves and holes are made at contact face of two inner rings, therefore the bearing application design is simplified. On both sides of the bearing mounted are steel seals, or optional rubber seal or nylon seals. All outside surfaces of the bearing components are phosphate to ensure the bearing able to work in the open air.
