Self-Aligning Ball B. FAG 2204 -TVH-C3
The FAG 2204 -TVH-C3 self-aligning ball bearing (20x47x18 mm) compensates for misalignment and, with its polyamide cage and C3 bearing clearance, allows for thermal expansion.
The FAG 2204 -TVH-C3 self-aligning ball bearing is a double-row rolling bearing made from standard bearing steel (100Cr6) with a 20 mm cylindrical bore. Thanks to the common hollow-spherical raceway in the outer ring, this design compensates for misalignment and shaft deflection during operation. The open bearing has an outer diameter of 47 mm and a width of 18 mm. Design engineers and maintenance personnel use this design primarily in bearing seats where angular misalignment between the shaft and housing may occur.
What is the 2204 -TVH-C3 self-aligning ball bearing suitable for?
This double-row roller bearing is suitable for designs where shaft deflection or misalignment needs to be compensated for. Thanks to the hollow spherical raceway of the outer ring, the sets of balls flexibly adapt to angular misalignment. Typical applications are found in general mechanical engineering, particularly in long shaft guides or separate bearing housings. As this is an open bearing without integrated seals, lubrication is provided by the surrounding housing system. The permissible temperature range is from –30 to +120 degrees.
What are the advantages of the polyamide cage and the C3 clearance?
The suffix TVH denotes a polyamide cage, which ensures quiet running and reduces friction within the ball set. The designation C3 indicates a slightly increased radial clearance compared with the standard version. This increased clearance helps to prevent the bearing from becoming stressed should temperature differences arise between the inner and outer rings during operation, or should tight fits reduce the bearing clearance. In conjunction with tolerance class P0 (ABEC 1), this provides a dimensionally stable component for industrial applications.
What are the dimensions of the 2204 -TVH-C3 self-aligning ball bearing?
The dimensions are 20 mm bore diameter (internal diameter), 47 mm external diameter and 18 mm width. These standard dimensions allow the double-row roller bearing to be fitted into standardised housing seats. These three key dimensions serve as a direct reference for checking the fit accuracy during repairs or new designs.
What does the bearing clearance C3 mean for this self-aligning bearing?
C3 denotes a slightly increased radial bearing clearance compared with the standard CN design. The additional clearance between the rolling elements and the raceways compensates for thermal expansion caused by heat build-up during operation. Furthermore, the C3 clearance prevents the rolling elements from becoming jammed if tight shaft or housing fits cause the inner ring to expand or the outer ring to be constricted.
What does the suffix ‘TVH’ stand for at FAG?
The suffix ‘TVH’ indicates a polyamide cage. This cage material absorbs shocks elastically, runs more quietly than metal versions and reduces the weight of the rotating component. The material is designed for use within a defined temperature range of -30 to +120 degrees, which it can withstand whilst retaining its dimensional stability.
How is the open pendulum ball bearing lubricated and sealed?
As an open roller bearing, this design does not feature any factory-fitted sealing washers. Grease or lubricating oil must be supplied via the housing design. To prevent the ingress of dirt and moisture, external housing seals must be fitted. This allows the lubricant to be selected according to the specific operating environment.
What is the tolerance class of the 2204 spherical roller bearing?
This rolling bearing complies with tolerance class P0 (also referred to as standard tolerance PN or ABEC 1). The manufacturing tolerances relating to dimensional, geometric and running accuracy meet the standard requirements of industrial mechanical engineering. The bearing is therefore suitable for series production applications as well as for replacement during maintenance.
Why does a self-aligning ball bearing compensate for angular misalignment?
The outer ring of the bearing has a continuous hollow spherical raceway, the centre of curvature of which lies on the bearing axis. This allows the inner ring, the cage and the two rows of balls to pivot freely within the outer ring. Static misalignments resulting from assembly, as well as dynamic shaft deflections under load, are compensated for with minimal friction.
