Designation explained
What 6416 means
Standard bearing numbers encode the type, the dimension series and the bore. Anything after the base number — seals, clearance, cage — is a suffix.

16 | 16 → 80 mm bore (16 × 5) |
Variants
Common 6416 variants
Suffixes change the bearing without changing its boundary dimensions. The exact letters differ between manufacturers — always order by the full designation from the maker you choose.
| Suffix | Example | Meaning |
|---|---|---|
Z / ZZ (2Z) | 6416-ZZ | Metal shield on one / both sides; keeps out coarse dirt, low friction |
RS / 2RS | 6416-2RS | Rubber contact seal on one / both sides; better protection against dust and water |
C2 | 6416-C2 | Internal radial clearance smaller than normal |
CN (no suffix) | 6416 | Normal internal clearance |
C3 | 6416-C3 | Internal clearance greater than normal — common for electric motors and heated shafts |
C4 | 6416-C4 | Internal clearance greater than C3 |
| Manufacturer | Shields both sides | Contact seals both sides |
|---|---|---|
| SKF | 6416-2Z | 6416-2RS1 |
| FAG (Schaeffler) | 6416-2Z | 6416-2RSR |
| NSK | 6416-ZZ | 6416-DDU |
| NTN | 6416-ZZ | 6416-LLU |
| Koyo (JTEKT) | 6416-ZZ | 6416-2RS |
6416-2RS (sealed)
- Rubber contact seals on both sides
- Best protection against dust, water and grease loss
- Slightly more friction and a lower speed limit
- Choose for dirty, wet or outdoor use
6416-ZZ / 2Z (shielded)
- Metal shields on both sides, small gap to the inner ring
- Keeps out coarse dirt; not water-tight
- Lower friction, higher speeds
- Choose for clean, fast-running applications

About these dimensions. Boundary dimensions follow ISO 15 (radial bearings — boundary dimensions, general plan), dimension series 04, and are the same for every manufacturer of a standard 6416. Chamfers, load ratings, speed limits and weight depend on the manufacturer and design and are not shown — use the maker's datasheet for engineering decisions. Last checked 9 October 2026.

What size is a 6416 bearing?
A 6416 is a deep groove ball bearing with a 80 mm bore, 200 mm outside diameter and 48 mm width (80 × 200 × 48 mm). These boundary dimensions follow the ISO dimension plan, so they are the same across manufacturers.
What does 6416-2RS or 6416-ZZ mean?
Same size, different closures: 2RS has rubber contact seals on both sides, ZZ (2Z) has metal shields on both sides. Manufacturers use different letters for the same idea — for example NSK DDU or NTN LLU for contact seals.
Can I replace 6416 with another bearing of the same size?
Other bearing types can share the same 80 × 200 × 48 mm envelope, but a different type has different load directions, speed limits and mounting needs. Same dimensions alone do not make two bearings interchangeable.
Where are the load ratings and speed limits?
They depend on the manufacturer and internal design, so we do not list a single value. Check the datasheet for the exact full designation you intend to use.
