Designation explained
What 51107 means
Standard bearing numbers encode the type, the dimension series and the bore. Anything after the base number — seals, clearance, cage — is a suffix.
| Part | Meaning |
|---|---|
5 | Thrust ball bearing, single direction |
11 | Dimension series 11 (thrust) |
07 | 07 → 35 mm bore (07 × 5) |
Variants
Common 51107 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 |
|---|---|---|
(no suffix) | 51107 | Standard single-direction design: shaft washer, housing washer, ball and cage assembly |
M / TN | 51107-M | Cage material: brass (M) or polyamide (TN) — varies by size and maker |
