Product Description

What this part is

SKF 7009CTCC78G1 angular contact ball bearing. Brand: SKF. Manufacturer Part Number: 7009CTCC78G1. Bearing Type: Angular contact ball bearing. Series: 7000. Base Number: 7009. Bore: 45 mm. Outside Diameter: 75 mm. Width: 16 mm. Bore Type: Straight. Closure Type: Open. Number of Rows: 1. Rolling Elements: Ball. Bearing Material: Chrome steel. Design Units: Metric. Country of Origin: United States.

Decoding the designation

Contact Angle: 15°, from the C. Cage Material: Phenolic. Cage Type: Outer-ring land-riding, machined. The carton carries the Fafnir designation 2M9109WI CR alongside the SKF number, and the two agree: the Fafnir 9100WI series maps to the ISO 70xx family, so 9109 is a 7009, and CR is Fafnir for a phenolic outer-ring land-riding cage.

What these specs mean in practice

Internal Clearance: CN. Maximum Operating Temperature: 120 °C. Minimum Operating Temperature: -30 °C. Lubricant: grease or oil. Item Weight: 0.53 lbs. A 15° contact angle is the shallowest in the angular contact range: it trades thrust capacity for speed, which is why it pairs with a machined phenolic cage on spindle work. The phenolic cage is light and self-lubricating and runs on the outer ring land rather than being guided by the balls.

Quantity and configuration

Unit Quantity: 1 Pc. A single bearing, complete with inner ring, outer ring, ball complement and cage.

Interchange guidance

Same-envelope 15° references: NSK 7009C and FAG B7009-C, both 45 x 75 x 16 mm on a 15° contact angle. A 7009 in a different angle execution shares the same envelope but is a related size rather than a substitution, because the angle changes the load split.
