HK 1512 (Needle Roller bearing)
The HK 1512 is a Needle Roller bearing with boundary dimensions of 15 x 21 x 12 mm (bore x outside diameter x width). It has a basic dynamic load rating of 9.4 kN and a basic static load rating of 13 kN.
Cross-Reference
| Manufacturer | Reference |
|---|---|
| SKF | HK 1512 |
| Timken | HK1512 |
| FAG (Schaeffler) | HK1512 |
Cross-references are matched on the ISO 15 boundary dimensions
(15 x 21 x 12 mm) and bearing type, which is what makes parts interchangeable. The
suffixes (e.g. -2RS, -2Z, -E1) encode seals, shields, and internal design
variants, not the envelope size.

Type & Application Notes
Needle Roller bearings are compact, high radial capacity within a thin radial envelope. The HK 1512 is commonly found in connecting rods, transmissions, and space-constrained pivot points. Dynamic rating 9.4 kN sets the load a bearing can carry for a one-million-revolution rating life (L10), while the static rating 13 kN governs the maximum load a stationary bearing can withstand without permanent deformation.
Interchange Notes
When substituting the HK 1512:
- Match the boundary dimensions (15 x 21 x 12 mm) exactly — this is what guarantees fit.
- Match the bearing type (Needle Roller); mixing roller and ball types changes stiffness, speed limits, and load capacity.
- Match or exceed the dynamic load rating (9.4 kN) for the intended life.
- Respect the seal/shield suffix the application requires (open, Z, 2Z, RS, or 2RS).
