RHP 7219ETSULP4 super precision angular contact ball bearing. Bore: 95 mm. Outside diameter: 170 mm. Width: 32 mm. Series: 72, ISO dimension series 02. Single-row angular contact ball bearing, straight bore, open, universally ground for use singly or matched with another bearing of the same designation.
Contact Angle: 25°. Cage: machined laminated phenolic, outer-ring guided. Grouping: SU, single universal. Preload: Light, 1,370 N axial. Precision Grade: P4, equivalent to EP7, ABEC 7 and ISO Class 4. The same bearing carries the designations B7219X3-TA-UL-EP7, 3MM219WI CR SUL, 7219A5 and 7219AC.
Dynamic radial load rating (Cr): 127,000 N. Static radial load rating (C0r): 107,000 N. Axial stiffness at light preload: 308 N/µm. A 25° contact angle carries more thrust and gives greater axial stiffness than a 15° bearing in the same envelope, at a lower speed ceiling. Light preload is the level chosen for most spindle work, where loads and speeds are not extreme. Limiting speed: 11,100 rpm on oil/air, 7,200 rpm on grease. Maximum recommended operating temperature: 120 °C. Rings and balls are through-hardened carbon chrome bearing steel to SAE 52100.
1 Pc. Universal face control means the inner and outer rings are the same width and the ring faces are adjusted at manufacture, so two of these bearings clamp up to the light preload value back-to-back or face-to-face without custom spacers, and share load equally in tandem.
Shaft abutment diameter (d1): 107 mm minimum. Housing abutment diameters: D1 158 mm maximum, D2 163 mm maximum. Maximum shaft fillet radius: 2.5 mm. Maximum housing fillet radius: 1.5 mm. Effective load centre (a): 123.6 mm. Internal volume for grease charging: 118.3 cm³. Mass: 2.63 kg. The high point of radial runout is marked by a burnished spot on the inner ring face and by a V line on the outer ring outside diameter; the V line also shows the direction of the contact angle.
Equivalents at the same contact angle, preload and precision class: SKF 7219 ACDGB/P4A (DGB is the light preload code; DGA is extra light and DGC medium), FAG B7219-E-T-P4S-UL, NSK 7219A5TRSULP4, Timken Fafnir 3MM219WI CR SUL. The 15° version of the same envelope, 7219CTRSULP4, is a related size.
