An RHP 7020E-T-SUL-P4 super-precision angular contact ball bearing with a 100 mm bore, a 150 mm outside diameter and a 24 mm width. It has a phenolic cage and is single universally ground for light preload.
7020: 70 angular contact series, 100 mm bore, 150 mm OD, 24 mm width. E: 25° contact angle in the RHP scheme. T: phenolic cage. SUL: single universally ground, light preload. P4: precision class 4, equivalent to ABEC 7.
A 25° contact angle carries substantially more thrust and gives higher axial rigidity than a 15° bearing of the same envelope, which is what a large boring or milling spindle needs when the cut pushes along the axis; the trade is a lower speed ceiling. Light preload keeps friction and heat generation down, so a large-bore spindle stays thermally stable over long cycles. Universal grinding means the ring faces are finished so any two bearings of this designation clamp into a light-preload set without shimming, back-to-back, face-to-face or in tandem. The phenolic cage is light and self-lubricating and quiet at speed, with a lower temperature ceiling than brass.
Bore: 100 mm (3.9370 in). Outside diameter: 150 mm (5.9055 in). Width: 24 mm (0.9449 in). Contact angle: 25°. Preload: light (L). Precision class: P4, ABEC 7. Cage material: phenolic. Number of rows: 1. Rolling elements: steel balls. Closure: open. Grinding: single universally ground.
The bearing is new old stock with staining on the ring surfaces from storage.
Supplied as 1 Pc, a single universally ground bearing.
Genuine equivalents are 25° ABEC 7 universally ground light-preload bearings in the same 100x150x24 mm envelope: FAG B7020-E-T-P4S-UL, NSK 7020A5TRSULP4, SKF 7020 ACD/P4A in light preload and Fafnir 3MM9120WI-SUL. The 15° build of this size, coded C by RHP and NSK, is a related size rather than an interchange, and medium or heavy preload versions change spindle stiffness and running temperature.
