7215: 75 mm bore, ISO 72 medium section, angular contact. T: phenolic cage. DU: two bearings, universally ground and matched as a duplex set, so they mount back-to-back, face-to-face or in tandem. L: light preload. P4: ABEC 7 tolerance class, given as EP7 in RHP’s own grading. The carton also carries the forms 7215 T DUL P4, 7215-B and the Fafnir cross MM215WI CR DUL.

Light preload gives the lowest friction and the least heat of the three preload classes while still holding the balls in defined contact through load reversal. Universal grinding holds the ring faces to a common width, so the pair sets its own preload when clamped, with no shims or spacers. P4 / EP7 tolerances hold bore, outside diameter and runout to spindle grade, keeping shaft position repeatable. The phenolic cage rides on the outer ring land: low mass, quiet running, and a 120 °C ceiling.
Unit Quantity: 2 Pc. One matched duplex pair, universally ground, light preload, open on both faces.
Straight bore, so the inner rings seat on a cylindrical shaft journal. Clamping the ground faces together sets the preload. Preloaded bearings are set at the factory, so no internal clearance figure applies. Operating temperature range: -30 °C to 120 °C.
Same envelope, 75 x 130 x 25 mm: ISO 7215 in every maker’s numbering, SKF 7215 CD/P4A, and the Fafnir cross MM215WI CR DUL on the carton.
