FAG7204BTVP.P5.DULAngular Contact Ball Bearing Matched Pair – 20 mm ID, 47 mm OD, 14 mm Width, Open, 40°, P5, Light Preload

Product Description

What this part is
FAG 7204B.TVP.P5.DUL is a matched pair of single-row angular contact ball bearings, 20 mm bore, 47 mm outside diameter, 14 mm width per bearing. The current Schaeffler designation for the individual bearing is 7204-B-XL-TVP-P5-UL, supplied here as a universally matchable set of two. Open on both faces, chrome bearing steel rings and balls.

Designation decode
7204: ISO 72 series, 04 bore code, 20 mm bore.

B: FAG design variant for a 40 deg contact angle.

XL: current Schaeffler optimised-design suffix.

TVP: glass-fibre reinforced PA66 window cage.

P5: dimensional and running accuracy class, equivalent to ABEC 5.

DUL: duplex set of universally matchable bearings ground for light preload.

What these figures mean in practice
A 40 deg contact angle carries substantially more axial load and gives a stiffer axial location than a 15 deg or 25 deg bearing of the same envelope, trading some speed capability for it. The glass-fibre reinforced polyamide cage is lighter than machined brass and runs quietly at speed. Light preload sets the axial stiffness at assembly, so the mounted pair runs at a defined position with the internal setting established by the ground ring faces.

Quantity and configuration
Two bearings, supplied as one matched pair. Universal matchability means the pair mounts back-to-back, face-to-face or in tandem, with light preload established when the abutting ring faces are clamped together.

Interchange guidance
7204-B-XL-TVP-P5-UL is the current Schaeffler designation for the single bearing. 7204B.TVP.P5.UO is the same envelope matched for a clearance-free rather than light-preload setting. 7204-B-TVP-P5-DUM is the same envelope at medium preload. SKF 7204 ACD/P4ADGA and NSK 7204A5TYNDBL are same-envelope precision bearings at other contact angles.
