A single-row super-precision angular contact ball bearing, 95 mm bore × 200 mm outside diameter × 45 mm width, in the ISO 7319 envelope.
7319 — single-row angular contact ball bearing, 300 heavy dimension series, bore code 19, giving a 95 mm bore.
T — phenolic cage.
SU — single bearing, universally ground for matching.
L — light preload.
P4 — ISO precision class 4, equivalent to ABEC 7. RHP writes the same class as EP7.
A single-row angular contact ball bearing takes thrust in one direction only, which is why these bearings are normally used in pairs or stacks so the arrangement carries thrust both ways. The 300 series is the heavy envelope: at 95 mm bore the 200 mm outside diameter and 45 mm width give a much larger ball complement and far more load capacity and rigidity than a 7219 in the same bore, and correspondingly less speed capability. Light preload keeps contact loads and heat generation low. Phenolic places the working temperature ceiling near 120 °C.

Single bearing, 1 Pc. Universal grinding allows it to be stacked back-to-back, face-to-face or in tandem with matching bearings of the same designation.
Mounting is an interference fit on the shaft and a close fit in the housing bore, both held to super-precision spindle limits. Faces seat against square ground shoulders, and a runout error at the shoulder transfers directly into the raceway.
A substitution within the 7319 envelope is governed by contact angle and precision class, so the matching designation is a 7319 in P4 with the same angle letter and the same light preload — for example the RHP 7319X4TUEP7, which is the same bearing in RHP’s own class notation. The 7219 shares the 95 mm bore in the lighter 200 series, which makes it a related size rather than an interchange.
