RHP 7209-T-DUL-P4, a matched duplex pair of single-row angular contact ball bearings. Boundary dimensions 45 mm bore × 85 mm outside diameter × 19 mm width per bearing.
72 – single-row angular contact ball bearing, ISO dimension series 02
09 – bore code, 09 × 5 = 45 mm bore
no angle letter – 40° contact angle in the RHP scheme, the form written 7209B elsewhere
T – phenolic cage
DU – duplex, a pair ground to run together
L – light preload
P4 – ABEC 7 precision class, RHP equivalent EP7
At 40° this is the high-thrust end of the angular contact range: axial capacity is well above a 15° or 25° bearing of the same size, and limiting speed is lower. Mounted as a duplex pair the set locates the shaft in both directions under a built-in light preload, which keeps running friction and heat generation down while still removing axial play. A phenolic cage suits the higher-speed end of the duty range.
Bore: 45 mm (1.7717 in)
Outside diameter: 85 mm (3.3465 in)
Width: 19 mm (0.7480 in) per bearing
Total width mounted: 38 mm (1.4961 in)
Contact angle: 40°
Rows: 1 per bearing
Preload: light (L)
Precision class: P4 (ABEC 7), RHP equivalent EP7
Cage: phenolic
Closure: open
2 Pcs, one matched duplex pair.
The pair mounts as a unit in the orientation marked on the outer rings, ground faces together, so preload comes from the matched ring-face offset rather than from clamp-up force. Full preload develops once the inner rings are clamped solid against the shaft shoulder and nut and the outer rings against the housing shoulder.
Same-spec 40° light-preload duplex equivalents in other schemes: RHP B-series B7209TDULEP7, FAG 7209-B-TVP in its matched UL form, Nachi 7209BDUGLP4, NSK 7209BDULP4. The 15° 7209-C and 25° 7209-E forms, medium and heavy preload variants, and single bearings are related sizes in the same 45 x 85 x 19 mm envelope rather than interchanges.
