The FAG 4218 -B-TVH deep-groove ball bearing, with two rows of balls and a 90 mm bore, provides a high-load-capacity bearing solution for demanding industrial applications.
The double-row deep-groove ball bearing 4218 -B-TVH provides designers and maintenance engineers with an open rolling bearing for shafts with a diameter of 90 mm. FAG manufactures rings and rolling elements from standard 100Cr6 bearing steel to tolerance class P0 (ABEC 1). Thanks to the two rows of balls, the unit can withstand higher radial loads than single-row variants with a comparable bore. The component does not require an integrated seal and features a cylindrical outer ring without a flange or groove.
Designs requiring higher radial load capacity and with limited axial installation space benefit from the double-row configuration of this design. The 4218 -B-TVH deep groove ball bearing is primarily used in bearing arrangements where shaft diameters of 90 mm are accommodated and increased radial loads are applied. As this is an open bearing, it is preferably integrated into sealed housings which feature their own sealing system to prevent the ingress of contaminants and allow for continuous oil or grease lubrication.
The letters ‘TVH’ in the suffix combination denote a lightweight, solid polyamide cage which guides the rolling elements and dampens running noise during operation. Together with the standard radial bearing clearance, the bearing is suitable for applications with typical operating temperatures and standard fit conditions on the shaft and housing. The permissible temperature range extends from -30 °C to +120 °C, enabling the component to cope with a wide thermal range in everyday industrial use.
Two parallel rows of balls in an outer ring with a diameter of 160 mm enable the bearing to withstand higher radial loads compared with single-row deep-groove ball bearings of the same bore size. The integrated polyamide cage ensures quiet guidance of the rolling elements.
With an internal diameter of 90 mm, an external diameter of 160 mm and a width of 40 mm, the bearing fits onto corresponding 90 mm shafts in housing bores with a diameter of 160 mm.
At FAG, the suffix TVH denotes a solid polyamide cage. This type of plastic cage is characterised by its low weight and elastic running characteristics. It contributes to smooth ball guidance and limits the upper operating temperature to +120 °C.
This design features standard radial bearing clearance. This standard radial clearance is suitable for applications where there are no extreme temperature differences between the inner and outer rings, and where standard market fit tolerances are used for the shaft and bearing housing.
The permissible operating range for this version is from -30 °C to +120 °C. Both the 100Cr6 roller bearing steel used and the polyamide cage retain their dimensional stability and mechanical properties within this range.
As the bearing is supplied ex works without either cover plates or sealing lips, the raceways and balls are fully exposed. The bearing must therefore be protected from contaminants and moisture by means of housing seals, whilst the lubricant is retained inside the housing.
