Standard double row deep groove ball bearings are 4200A, 4300A type. Type A bearings have no ball gaps. Two reinforced nylon cages are inserted from both sides of the bearing. In addition to having a radial load capacity 1.62 times higher than that of single row deep groove ball bearings, double row deep groove ball bearings can also bear axial loads. Standard deep groove ball bearings have ordinary radial internal clearance.
Centering error
When there is a misalignment between the inner and outer rings of a double row deep groove ball bearing, it will cause additional load. Thereby increasing the load borne by the steel ball and cage and shortening the working life of the bearing. Therefore, the allowable angle error is only 2 arc minutes. Any larger angular error will result in an increase in noise.
Double row deep groove ball bearings are very suitable for bearing arrangements where the load carrying capacity of a single row bearing is inadequate. For the same bore and outside diameter, double row bearings are slightly wider than single row bearings in the 62 and 63 series, but have a considerably higher load carrying capacity.
Double row deep groove ball bearings are only available as open bearings (without seals or shields).
For bearing selection and technical details refer to the product table and set the filter "Design" to "Double row".
Cages
EASIER double row deep groove ball bearings are fitted with two snap-type, ball centred glass fibre reinforced PA66 cages (designation suffix TN9).
When used at high temperatures, some lubricants can have a detrimental effect on polyamide cages. For additional information about the suitability of cages, refer to Cages.
