Product Description

What this part is

NSK 6911VVC3 single-row deep groove ball bearing from the thin-section 69 series, with a non-contact rubber seal on each side and C3 radial internal clearance. Bore Diameter: 55 mm. Outside Diameter: 80 mm. Overall Width: 13 mm.

Decoding the designation

6911 — ISO 61911 size, dimension series 19, 55 x 80 x 13 mm.

VV — non-contact rubber seals both sides.

C3 — radial internal clearance greater than normal, suited to interference fits and higher running temperatures.

What these specs mean in practice

Closure Type: Non-contact seals both sides. The seal lip runs close to the inner ring without touching it, retaining the grease fill and excluding dust with lower friction and higher speed capability than contact seals.

Lubricant: Grease. Internal Clearance: C3. Rolling Elements: Ball. Number Of Rows: 1. Bore Type: Straight. Bearing Material: Bearing steel. Snap Ring Included: No. Harmonization Code: 8482.10.50.00. Country of Origin: Japan.

Quantity and configuration

Unit Quantity: 1 Pc. One complete sealed bearing.

Interchange guidance

NTN 6911LLU and Koyo 6911-2RS are the same size with contact seals, which run with more friction and a lower speed limit, and need C3 specified to match the clearance.
