SNR Machline super-precision angular contact ball bearing. 17 mm bore, 35 mm outside diameter, 10 mm width. Contact Angle: 15 degrees. Cage Material: Stratified, cotton-fabric-reinforced phenolic, machined and outer-ring-land guided. Supplied as a universal duplex pair at light preload, ISO class 4. Mounted as a pair the set occupies 20 mm of shaft length. A small, very high-speed spindle bearing: published limiting speed is 41,000 rpm on grease and 65,000 rpm on oil.
7003 is the ISO 70-dimension series angular contact envelope, 17 x 35 x 10 mm. C is SNR’s code for 15 degrees; H is 25 degrees. DU is duplex universal, flush ground, mountable back-to-back, face-to-face or in tandem. J74 combines preload and precision: the middle digit gives preload class, 7 for light, and the final digit gives precision, 4 for ISO class 4, so J74 is light preload, ISO class 4.
15 degrees is the shallow, high-speed spindle angle; light preload is the lowest-friction and lowest-heat preload class; the phenolic cage tolerates the resulting conditions. Together they give a 41,000 rpm grease rating on a 17 mm bore, suited to high-frequency spindles, small grinding spindles and precision instrument drives. Dynamic Load Rating: 7.40 kN (1,664 lbf), single bearing. Static Load Rating: 4.45 kN (1,000 lbf), single bearing. Operating Temperature Range: -40 to 120°C.
DU designates a matched pair ground as a set. Bearings from a common original set reproduce the specified light preload when clamped together.
The carton marking 7003-C-T-DUL-P4 describes the same part in Schaeffler-style notation: C denotes 15 degrees in both schemes, T is the machined phenolic cage, DUL matches SNR’s J74 light preload, and P4 is ISO class 4. Comparable parts from other makers: Schaeffler B7003-C-T-P4S-DUL, SKF 7003CD, and the Fafnir/Timken 2MM9103WI family. A 7003A5 at 25 degrees or 7003A at 30 degrees has this size but is not a substitute.
