Barrel Roller Bearings FAG 20213 -K-TVP-C3

The FAG 20213 -K-TVP-C3 spherical roller bearing, with dimensions of 65 × 120 × 23 mm, a tapered bore and C3 clearance, reliably compensates for misalignment.

The 20213 -K-TVP-C3 spherical roller bearing is a single-row rolling bearing designed for high radial loads whilst accommodating angular misalignment of the shaft. With a bore of 65 mm, an outer diameter of 120 mm and a width of 23 mm, the barrel-shaped row of rollers accommodates angular misalignments between the shaft and the housing. Maintenance engineers and designers value this design, which complies with tolerance class P0 (ABEC 1), as it effectively absorbs shock loads during continuous industrial operation.

What is the 20213 -K-TVP-C3 barrel bearing suitable for in operation?

This bearing type is primarily used where elastic shaft deflection or misalignment occurs as a result of the design. Thanks to its spherical outer raceway, the bearing automatically compensates for misalignment. When combined with suitable housings, the unit performs reliably in demanding bearing locations. The open design without seals allows for a lubricant supply – either grease or oil – as required via the surrounding housing structure.

What are the advantages of a tapered bore and C3 clearance?

The tapered inner bore, designated K (1:12 taper), simplifies mounting on a shrink sleeve or a stepped shaft. During radial press-fitting, the radial clearance is measurably reduced. This is where the increased C3 bearing clearance comes into play: It helps to ensure that sufficient residual bearing clearance is maintained after the inner ring has been tightened and following operational heating. The polyamide cage (TVP) reduces the component’s weight and operates quietly within a temperature range of -30 to +120 degrees.
