NSK7006A5TYDUMAngular Contact Ball Bearing Matched Pair – 30 mm ID, 55 mm OD, 13 mm Width, Open, 25° Contact Angle, Medium Preload, ABEC 7

Product Description

What this part is: NSK 7006A5TYDUM angular contact ball bearing, supplied as a matched duplex pair. Bore: 30 mm. Outside Diameter: 55 mm. Overall Width: 13 mm per bearing. Contact Angle: 25°. Number Of Rows: 1 per bearing. Rolling Elements: Steel balls. Bore Type: Straight. Closure Type: Open. Cage Type: Ball-guided. Precision Class: ABEC 7 / P4. Running Accuracy — Radial And Axial Runout: P4. Preload: Medium. Internal Clearance: N/A. Bearing Material: Bearing steel. Series: 7000. Dynamic Load Rating: 18.2 kN per bearing. Static Load Rating: 9.80 kN per bearing. Limiting Speed: 23,600 rpm on grease, 35,300 rpm on oil-air. Unit Quantity: 2 Pc. Decoding the designation: A5: 25° contact angle. TY: ball-guided cage. DU: universally ground duplex bearings, so any two mount together back-to-back, face-to-face or in tandem. M: medium preload. Searchable variants: 7006A5TYDUM, 7006 A5 TY DUM, 7006A5-TY-DUM, 2MM9106WICRDUM, B7006E. What these specs mean in practice: A 25° contact angle carries more thrust and less speed than a 15° execution, which suits a spindle seeing a substantial axial component. Medium preload keeps the balls in defined contact through load reversal, raising axial stiffness and running accuracy. P4 running accuracy holds radial and axial runout close, so the shaft locates precisely. The oil-air speed figure is roughly half again the grease figure, so the lubrication method sets the usable ceiling. Quantity and configuration: Unit Quantity: 2 Pc. One matched duplex pair, universally ground, medium preload. Mounting Arrangement: Universal. Fitting notes: Clamping the ground faces together establishes the preload. Preloaded bearings are set at the factory, so no internal clearance figure applies. Interchange guidance: Same envelope, angle and preload class: SKF 7006 ACD/P4ADGB and Fafnir 3MM9106WI-DUM. A 15° execution on the same envelope, such as an SKF 7006 CE/P4A, is a related size rather than a substitute.
