NSK 7914A5TYNDBP4Y+KL-01 super-precision angular contact ball bearings, supplied as a matched pair. Series: 719, extra light section. Bore: 70 mm. Outside Diameter: 100 mm. Width: 16 mm per bearing. Open on both faces, polyamide cage, steel balls on steel raceways. Searchable forms of the designation: 7914A5TYNDBP4Y, 7914 A5 TYN DB P4Y, 7914A5TYNDBP4Y+KL-01, 7914A 5 TYN DB P4 Y + KL-01, 71914A5TYNDBP4Y.
Contact Angle: 25°, from the A5 designation. Cage: TYN — polyamide. Mounting Arrangement: DB — back-to-back. Precision Class: P4Y, a special NSK class held tighter than P4. Series 7914 is the ISO 719 extra light section, a thinner envelope than a 7014 of the same 70 mm bore.
A 25° contact angle carries more thrust and less speed than a 15° bearing on the same envelope, which suits spindles seeing combined radial and axial load. A back-to-back pair takes thrust in both directions and resists moment loading, so it locates a shaft axially in a single bearing position and holds it square. A polyamide cage is light, quiet and self-lubricating, and it tolerates momentary lubrication interruption better than a machined metal cage. P4Y raises running accuracy above standard ABEC 7, giving lower radial and axial runout at the spindle nose.
Two bearings. Unit Quantity: 2 Pcs. Matched back-to-back pair, ground so the two share a common preload when clamped together. Open bearings, lubricated on installation.
The two bearings are clamped against a common shoulder and locknut for the ground preload to take effect, with the wide outer-ring faces together for the back-to-back arrangement. Preloaded bearings run without internal clearance, so shaft and housing seats are held to super-precision tolerances.
Same-envelope 25° bearings from other makers: SKF 71914 ACD/P4A and FAG B71914-E-T-P4S, each sold as single bearings and ordered as a back-to-back pair. NSK 7914CTYNDBP4Y is a related size at a 15° contact angle. NSK 7014A5TYNDBP4Y is a related size on the heavier ISO 70 section.
