NSK 7205A5TYDUL super-precision angular contact ball bearings, supplied as a universally matchable duplex pair. Bore: 25 mm. Outside diameter: 52 mm. Width: 15 mm each, 30 mm stacked. Series: 7200. Bore form: straight. Closure: open.
A5: 25° contact angle. TY: ball-guided cage. DU: universally matchable duplex set, so the pair can be arranged back-to-back, face-to-face or in tandem. L: light preload. Searchable forms include 7205A5TYDUL, 7205-A5TY-DUL, 7205A5TY DUL and 7205A5.
Basic dynamic load rating: 20.0 kN per bearing. Basic static load rating: 9.80 kN per bearing. Limiting speed: 26,000 rpm on grease, 39,000 rpm on oil-air. Permissible axial load: 9.05 kN. Effective load centre: 16.5 mm. Light preload on a back-to-back or face-to-face pair is 143 N, giving 89 N/µm of axial rigidity. A 25° contact angle sits between the 15° high-speed and 30° high-thrust executions: more thrust capacity and stiffness than a 15° bearing, higher speed capability than a 30°.
Two bearings, a factory universally matchable pair. Because the faces are ground for universal matching, the two rings stack in any of the three arrangements without a spacer and reach the published preload on clamp-up.
Shaft abutment diameter: 31 mm minimum. Housing abutment diameter: 46 mm maximum, 47 mm on the outer shoulder. Shaft fillet radius: 1 mm maximum; housing fillet radius: 0.5 mm maximum. Recommended grease charge: 0.79 g per bearing.
FAG B7205-E-T-P4S-DUL covers the same envelope and preload class. 7205CTYDUL at 15° and 7205ATYDUL at 30° are related sizes rather than interchanges, because the contact angle changes both thrust capacity and speed rating.
