An NDH Q0LL14A precision angular contact ball bearing, single row, with a phenolic ball separator and a rust-preventive slush coating. 70 mm bore on the ISO 71914 envelope.
Q is the phenolic ball separator. 0LL is the dimension-series code; the 70 x 100 x 16 mm envelope corresponds to ISO 71914. 14 is the bore code, five millimetres per step, giving a 70 mm bore. A is the rust-preventive slush coating.
A phenolic separator is lighter than a steel one and runs quieter and cooler at speed, and it holds an oil film in the cage pockets, which is why New Departure used it on precision spindle bearings. The rust-preventive slush is a shelf-storage coating rather than a running lubricant, so it sits on the raceways as supplied. The 719 envelope is an extra-light section: at a 70 mm bore it gives only a 15 mm cross-section and a 16 mm width, which keeps the bearing compact and its mass low where housing space is tight.
Bore 70 mm (2.7559 in). Outside diameter 100 mm (3.9370 in). Width 16 mm (0.6299 in). One row, steel balls, phenolic separator, rust-preventive slush coating, open both faces.
1 Pc, a plain single bearing. The designation carries no matched-set arrangement block.
ISO base number 71914. Searchable forms are Q0LL14A, Q-0LL14-A, Q 0LL14 A, 7914 and 71914. New Departure Hyatt was a General Motors division and the line passed to Delphi, so buyers usually arrive from a current designation on the same envelope. Contact angle governs substitution on this envelope, so a 71914 in a stated angle grade is a related size until the angle is matched. An NDH designation carrying an H is the 25° grade, and DT, DB and DF blocks mark matched sets, all of which are different parts.
