NTN-SNR 7004HG1DUJ84-1/2PR super-precision angular contact ball bearing, ISO 70 dimension series, one piece from a universally matchable pair. Bore: 20 mm. Outside Diameter: 42 mm. Overall Width: 12 mm. Contact Angle: 25°. Number Of Rows: 1. Rolling Elements: Ball. Bearing Material: High carbon chrome steel. Closure Type: Open. Bore Type: Straight. Series: ISO 70.
7004 gives the ISO 70 dimension series and the 20 mm bore. H sets the Contact Angle: 25°. G1 gives the cage — Cage Material: Phenolic (laminated resin), Cage Type: Machined, outer-ring centred. J84 sets Preload: Medium and Precision Class: ISO Class 4 (ABEC 7 / P4). The -1/2PR suffix gives the sale unit: Unit Quantity: 1 Pc. Searchable forms of the number: 7004HG1DUJ84, 7004HG1DUJ84-1/2PR, 7004-H-G1-DU-J84, 7004 H G1 DU J84.
A 25° contact angle carries more thrust and less speed than a 15° angle, which suits machine-tool spindles and ball-screw ends working against a steady axial load. Cage Material: Phenolic (laminated resin) runs light and quiet at high speed and takes oil-mist and oil-air lubrication. Cage Type: Machined, outer-ring centred holds the cage stable on the outer-ring land at speed. Precision Class: ISO Class 4 (ABEC 7 / P4) holds running accuracy close, giving low radial and axial runout. Preload: Medium fixes the axial stiffness of the mounted set. Internal Clearance: N/A — a preloaded set is stiffness-set rather than clearance-set.
Unit Quantity: 1 Pc — a single bearing from a factory-matched two-bearing set. Mounting Arrangement: Universal (DB, DF or DT). Universally matchable faces let this bearing stack back-to-back, face-to-face or in tandem against another piece of the same designation and reach the same preload in any of the three.
Carton cross-designations: FAG 7004E-T-DUM-P4, NSK 7004ETRDUMP4, Fafnir 3MM9104WI CR DUM and SNR 7004A5/ACD, all 25° universally matchable medium-preload executions on the same 20 x 42 x 12 mm envelope. SKF 7004 ACD/P4ADGB has the same size and angle at light preload. A 7004C or B7004-C execution shares the envelope at 15° rather than 25°.
