NSK7006CTYP5Angular Contact Ball Bearing – Straight Bore, 30 mm ID, 55 mm OD, 13 mm Width, Open, 15° Contact Angle, P5 Precision

Product Description

What this part is

NSK 7006CTYP5 super-precision angular contact ball bearing. Bore: 30 mm. Outside diameter: 55 mm. Width: 13 mm. Series: 7000, ISO 70 dimension series. Bore form: straight. Closure: open.

Decoding the designation

C: 15° contact angle. TY: ball-guided cage. P5: ISO precision class 5, equivalent to ABEC 5. Searchable forms include 7006CTYP5, 7006-C-TY-P5, 7006C TY P5 and 7006C. The carton also carries the Fafnir cross-reference 2MM9106WI CR.

What these specs mean in practice

Basic dynamic load rating: 19.1 kN. Basic static load rating: 10.3 kN. Limiting speed: 27,100 rpm on grease, 41,200 rpm on oil-air. Permissible axial load: 6.85 kN. Effective load centre: 12.2 mm. Static load factor f0: 14.9. A 15° contact angle is the high-speed, low-friction execution of this envelope: it runs faster and cooler than a 25° or 30° bearing and takes proportionally less thrust. P5 precision holds tighter bore, outside diameter and running-accuracy tolerances, giving closer shaft location and lower running vibration.

Quantity and configuration

Single bearing, single row, one piece. Thrust is taken in one direction, so the bearing is conventionally mounted against a second bearing or a shoulder.

Fitting notes

Shaft abutment diameter: 36 mm minimum. Housing abutment diameter: 49 mm maximum, 50 mm on the outer shoulder. Shaft fillet radius: 1 mm maximum; housing fillet radius: 0.5 mm maximum. Recommended grease charge: 0.64 g.

Interchange guidance

Same-specification equivalents: SKF 7006 CD/P5, FAG B7006-C-T-P5, Fafnir 2MM9106WI. 7006A5TYP5 at 25° and 7006ATYP5 at 30° are related sizes rather than interchanges, because the contact angle changes both thrust capacity and speed rating.
