Ball Bearings

Single-row deep groove ball bearings are designed to carry radial loads as well as axial loads in both directions, especially with increased radial clearance. At the same time the axial loads may compose
70% of unused radial load.
Deep groove ball bearings of the relevant design, with relevant cage material, with relevant lubrication operate at extremely high speeds.
Deep groove ball bearings hold fixed a shaft position relative to the housing in both directions. The bearings, not being a self-aligning, allow only small shaft misalignment in support (up to 10'), the value of which depends on the internal clearances, without decreasing the life. In this case the bearings must rotate at low rotational speed. The number of design variants of these bearings is large enough, and
most of them are standardized.
To simplify axial mounting the bearing can be designed with the snap ring groove in on outer ring, in which a snap ring is inserted during the mounting.
In order to simplify and reduce the maintenance costs the bearings are produced with seals and greased-for-life. Deep groove ball bearings are produced in two design variants: with metal shields and
rubber-metal seals. Seals can also be installed on one side.
There are also various designs of cages for deep groove ball bearings. The most common type is the ribbon-type cage of two steel semi-cages connected by rivets.
For special operating conditions solid brass, textolite and polyamidecages are used.
