FAGAngular Contact Ball Bearing – 20 mm Bore, 47 mm OD, 14 mm Width, 40° Contact Angle, Universal Design, Small Axial Clearance

Product Description

What this part is

A FAG 7204-B-TVP-UA single-row angular contact ball bearing, 20 mm bore by 47 mm outside diameter by 14 mm wide, open on both faces, with a 40° contact angle and a solid glass-fibre reinforced polyamide window cage. It is supplied in the universal design, so any two of these bearings can be set against each other without a ground spacer.

Decoding the designation

72 is the light dimension series and 04 gives the 20 mm bore. B marks the modified internal construction that carries the 40° contact angle. TVP is the one-piece glass-fibre reinforced polyamide cage. UA is the universal design with a small axial internal clearance across the matched pair.

What these specs mean in practice

The 40° contact angle is the highest-thrust option in the 7200 family, taking substantial axial load in one direction and combined load when paired. Dynamic load rating is 13.4 kN, static 7.65 kN, and the fatigue limit load 0.53 kN. Both reference and limiting speed sit at 18,000 rpm, which the polyamide cage supports through its low mass and good damping.

Universal design and pairing

Universal-design bearings are ground so that a pair mounted back-to-back (O), face-to-face (X) or in tandem needs no spacer or shimming. The UA code gives that pair a small axial internal clearance once clamped, which suits arrangements where thermal growth along the shaft is expected.

Quantity and configuration

Sold as one bearing. Each unit is universally matchable, so pairs and tandem sets are built from individual pieces of the same designation.

Fitting notes

The wide shoulder of the outer ring faces the direction of thrust in a single-bearing mounting. Mounting force is applied to the ring being fitted, never through the ball complement. Operating temperature range for the polyamide cage runs to 120 °C continuous.

Interchange guidance

7204-B-XL-TVP-UA is the current X-life designation of the same bearing. The 7204-B-TVP-UO differs only in having zero axial clearance across the pair, and the plain 7204-B-TVP is the standard single that is not universally ground — both are related sizes rather than direct substitutions where matched pairing matters.
