CAGES
CAGES
Cages (also referred to as retainers) make a vital contribution to overall bearing
performance. They maintain uniform ball spacing in the bearing as the balls pass into
and out of the load zone.
Cages can impact several bearing operational characteristics such as:
• Maximum rotational speed
• Torque characteristics
• Temperature limits
• Lubricant flow
There are a number of different cage types that are commonly used in deep groove
ball bearings, the most popular being the riveted steel cage. Table 1 describes the most
common cage types.
