NSK 6916 dimensions and catalogue data
NSK 6916 is a catalogue designation for a single-row deep groove ball bearing. Its published boundary dimensions are 80×110×16 mm (bore d × outside diameter D × width B).
The listed dynamic radial rating Cr is 27.4 kN and the static radial rating C0r is 24 kN. The grease-lubricated limiting speed for this closure column is 5600 r/min.
What this marking establishes
Open. Use the full marking for comparison; equal d×D×B dimensions do not establish interchangeability.
Using these figures safely
- The listed load ratings support bearing calculations; neither value is a universal permissible operating load. Actual life also depends on load direction, speed, lubrication, contamination and installation.
- Use the speed entry for the stated closure and lubrication condition. The open-bearing oil value must not be transferred to a double-sealed or double-shielded bearing.
- The shoulder diameters and fillet radius describe adjacent shaft or housing geometry, not alternative bearing boundary dimensions. Heavy axial loads and a rotating outer ring require an application-specific check.
- Clearance class, tolerance class, grease grade and vehicle or machine fitment are not established by this table row. A sealed or shielded catalogue designation is not a complete supply specification without its grease and other required suffixes.
- Optional N/NR groove and retaining-ring dimensions are not assigned to this record. Those options require their own complete designation and installation check.
