FAG Bearing S6208-2RSR

Product description of FAG Bearing S6208-2RSR

FAG Bearing S6208-2RSR Deep Groove Ball Bearings are versatile, self-retaining bearings. These bearings, which are of simple design, robust in operation and easy to maintain, are available in single row and double row designs and in open and sealed variants.

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. Due to their very low frictional torque, open bearings are suitable for high and very high speeds. Bearing designs with gap seals are suitable for high speeds.

Single row deep groove ball bearings are only suitable for compensating static misalignment s to a very limited extent. As a result, the bearing positions must be well aligned.

Double row deep groove ball bearings correspond in their structure to a pair of single row deep groove ball bearings but have two raceway grooves, each with one row of balls. Due to the larger number of rolling elements, they can be subjected to higher loads than single row deep groove ball bearings.

FAG Bearing S6208-2RSR,Double row bearings are used where the load carrying capacity of single row deep groove ball bearings is not sufficient. Since the bearings can also support loads due to tilting, they are suitable for particularly short shafts that are supported by only one bearing.

Technical information on deep groove ball bearings

FAG Bearing S6208-2RSR, Deep groove ball bearings are available in single row and double row designs. Single row bearings are particularly suitable where: • high and very high speeds are required • the bearing arrangement must be operated with very low friction • very low running noise is required, without reducing the speed, load carrying capacity and operating life of the bearing (Generation C) • high demands are made on the sealing of the bearing, without increasing heat generation or limiting the speed (Generation C) • the bearing position is to be designed particularly economically Double row bearings can be considered for bearing arrangements where: • the load carrying capacity of single row deep groove ball bearings is no longer sufficient • axial loads in both directions and/or tilting moments must be supported in addition to radial loads • a high load carrying capacity is required and the design envelope available in a radial and axial direction is relatively small

Single row deep groove ball bearings

FAG Bearing S6208-2RSR The bearings are available in open and sealed designs Single row deep groove ball bearings are available in open designs, as well as with seals on one or both sides. In the case of sealed bearings, either non-contact or contact seals are used. Provide additional seals in the adjacent construction In the case of unsealed bearings, sealing of the bearing position must be carried out by the adjacent construction. The sealing system should reliably prevent: • moisture and contaminants from entering the bearing • the egress of lubricant from the bearing

Generation C

For bearing assemblies with high speeds and lower requirements for sealing Non-contact seals are particularly suitable for applications with high speeds and high requirements for low heat generation. They are free from friction, except for a small amount of lubricant friction in the sealing gap. As a rule, non-contact seals do not undergo wear and therefore have an unlimited operating life.

FAG Bearing S6208-2RSR, Deep groove ball bearings with non-contact seals on one or both sides have the suffixes RZ and 2RZ, or BRS and 2BRS; the suffixes Z and 2Z indicate seals on one or both sides with sealing shields.

Z sealing shields for standard bearings and for bearings of Gen. C

Z sealing shields are made from sheet steel. They sit securely in the outer ring and form a narrow, non-contact seal gap relative to the surface of the inner ring.This sealing arrangement is particularly suitable for applications with a rotating inner ring, high to very high speeds and low contamination impact.

RZ seals for standard bearings of series 618 and 619

RZ seals are rubberized sealing washers with a sheet steel reinforcement, which sit securely in the outer ring and form a narrow, non-contact seal gap relative to the surface of the inner ring

BRS seals for bearings of Gen. C

BRS seals are rubberized sealing washers with a sheet steel reinforcement, which sit securely in the outer ring and form a narrow, non-contact seal gap relative to the surface of the inner ring, The seal is securely anchored in the outer ring. A recess incorporated in the inner ring forms a labyrinth in conjunction with the seal lip, which is filled with grease. The frictional behaviour of this seal is comparable with that of the Z sealing shield , however, the protection against ingress of dust and egress of lubricant is higher.
