Deep groove ball bearings
Deep groove ball bearings are among the most sold bearing types due to their versatility and value for money. Deep groove ball bearings can support radial as well as axial forces. Due to the low frictional torque they are suitable for high speeds.
Deep groove ball bearings with sealing washers on both sides - 2RS: The suffix 2RS behind the type number points to two sealing washers mounted on both sides. These seals are made of rubber-coated sheet steel reinforcements, close on the inner ring with a sealing lip and offer a high protective effect against dirt and moisture. Furthermore, the synthetical rubber material is resistant to a variety of aggressive materials.
Deep groove ball bearings with sealing shields on both sides - ZZ: The suffix ZZ behind the type number points to two sealing shields mounted on both sides. The sealing shields protect the interior of the bearing from the penetration of dirt particles as well as other foreign objects. However, the sealing effect is lower than in the case of the aforementioned sealing washers (suffix RS).
Single or double row as well as full ball deep groove ball bearings without cage are radially higher loadable. Versions with flange or slot and snap ring facilitate installation of the bearing. Bearings with increased internal radial clearance are suitable, for example, for special cases in which there are high temperature differences between the bearing rings. In addition to deep groove ball bearings made of bearing steel, bearings made of stainless steel, all-ceramic and hybrid bearings with ceramic balls are also available.

Designations for deep groove ball bearings
Prefixes and Suffixes
designation | description | properties |
---|---|---|
2RS | contact sealing washers (rubber) on both sides | for high sealing effect against dirt and moisture | more |
ZZ | contactless sealing shields (metal) on both sides | for particularly smooth running | more |
C3 | internal radial clearance greater than normal | for press fits of bearing rings (particularly high speeds) and larger temperature difference between inner- and outer ring | more |
TN9 | plastic cage (special order, only possible in case of larger purchase quantities) | for quiet running |
SS | inner- and outer ring, balls as well as the cage are made of stainless steel | for good corrosion resistance |
C | hybrid = inner- and outer ring are made of steel and the balls of ceramic (Si3N4) | suitable for particularly high speeds, high wear resistance, light, current-insulating |
CE | all-ceramic = inner- and outer ring as well as the balls are made of ceramic (Si3N4) | suitable for particularly extreme high speeds, extreme wear resistance, extreme longevity, very light, current-insulating |
F | flange at outer ring | allows for axial fixing, e.g. in mounting holes or housings |
NR | annular slot and snap ring | for form-fitting, axial fixing in a bore |
V | full complement ball set | for higher and impact loads, medium speeds |
Information for calculating the bearing bore
Multiply normal deep groove ball bearings from ..04 for the bore diameter by 5:00 – 10 mm
01 – 12 mm
02 – 15 mm
03 – 17 mm
04 – 4 x 5 mm = 20 mm
05 – 5 x 5 mm = 25 mm
etc.
