Deep groove ball bearings

Deep groove ball bearings are versatile, self-retaining bearings with solid outer rings, inner rings and ball and cage assemblies.

These products, which are of simple design, robust in operation and easy to maintain, are available in single and double row designs and in open and sealed variants. Due to the manufacturing processes used, open bearings can have turned recesses in the outer ring for seals or shields. Due to their low frictional torque, deep groove ball bearings are suitable for high speeds.

Radial and axial load capacity

Due to the raceway geometry and the balls used as rolling elements, deep groove ball bearings can support axial loads in both directions as well as radial loads, see link.

Compensation of angular misalignments

The angular adjustment facility of single row deep groove ball bearings is limited, so the bearing positions must be well aligned.

Misalignments can lead to unfavourable ball running and induce additional loads in the bearing that shorten the operating life. In order to keep these loads at a low level, only small adjustment angles are permissible (dependent on the load) for single row deep groove ball bearings, see section link.

Due to their internal construction, double row deep groove ball bearings do not have an angular adjustment facility. When using these bearings, therefore, misalignments are not permissible.

Single row deep groove ball bearings

Single row deep groove ball bearings are the most frequently used type of rolling bearing. They are produced in numerous sizes and designs and are particularly economical.

Sealing

Open bearings are suitable for high to very high speeds.

Deep groove ball bearings with the suffix 2Z have gap seals on both sides and are suitable for high speeds.

Bearings with the suffix 2RSR have lip seals on both sides made fromnitrile butadiene rubber NBR and are suitable for moderate speeds.

By agreement, we can supply bearings with non-contact BRS seals  on both sides (suffix 2BRS). These bearings have favourable frictional behaviour equivalent to that of bearings with Z seals . If the inner ring is stationary and the outer ring rotates, the lubricant loss is less than that in bearings with Z seals .

Lubrication

Open bearings can be lubricated with grease or oil.

Deep groove ball bearings with gap or lip seals on both sides are greased with a high quality grease and are lubricated for life.

Anti-corrosion protection

For applications requiring high levels of anti-corrosion protection, we offer corrosion-resistant deep groove ball bearings in sealed and open designs. The range is described in detail in TPI 64, Corrosion-resistant products.

Matched single row deep groove ball bearings

By agreement,deep groove ball bearings of series 160, 60, 62, 63, 64 and 618 are available in various arrangements as matched pairs of bearings, Figure 1.

Sets in an O arrangement (suffix DB) can support axial loads in both directions as well as tilting moments.

Sets in an X arrangement (suffix DF) can support axial loads in both directions but are not suitable for tilting moments.

For high axial loads from one direction, pairs of bearings in a tandem arrangement are suitable (suffix DT).

Double row deep groove ball bearings

Double row deep groove ball bearings correspond in their structure and function to a pair of single row deep groove ball bearings. They are designed for high to very high speeds and are used where the load carrying capacity of single row deep groove ball bearings is not sufficient.

Double row deep groove ball bearings are wider than single row deep groove ball bearings of the same bore and outside diameter but have a significantly higher load carrying capacity.

Sealing

Double row deep groove ball bearings are not sealed.

Lubrication

The bearings are open and are greased using a high quality grease.

Operating temperature

Open deep groove ball bearings can be used up to an operating temperature of +120 °C. For applications at temperatures above +120 °C, please contact us. Bearings with a diameter D of more than 240 mm are dimensionally stable up to +200 °C.

Deep groove ball bearings with lip seals can be used at operating temperatures from –30 °C to +110 °C, limited by the grease and sealing ring material.

Bearings with gap seals can be used from –30 °C to +120 °C.

Bearings with cages made from glass fibre reinforced polyamide are suitable for operating temperatures up to +120 °C.

Cages

Single row deep groove ball bearings without a cage suffix have a sheet steel cage.

Deep groove ball bearings with ball-guided solid brass cages are indicated by the suffix M.

The suffix Y indicates bearings with a sheet brass cage.

Double row deep groove ball bearings have cages made from glass fibre reinforced polyamide (suffix TVH).

Check the chemical resistance of polyamide to synthetic greases and lubricants with EP additives.

Aged oil and additives in the oil can impair the operating life of plastic cages at high temperatures. The oil change intervals must be observed.
