Product Features
- Drawn cup construction with thin-walled outer ring – provides high radial load capacity in a compact cross-section.
- Open-type design supports application-specific lubrication and allows for free oil circulation in transmission and clutch assemblies.
- Cross-referenced with INA HK1812 and SKF HK 1812 – verified aftermarket interchange available.
- Heat-treated bearing steel with precision-ground raceways – rated for 8.10 kN dynamic load and 10.90 kN static load.
- Operating temperature range of -30 to 140 °C supports diverse automotive under-hood environments.
Installation Notes
- Confirm bore diameter (18.00 mm) and outer diameter (24.00 mm) match your housing and shaft before installation.
- This bearing is designed for use on a hardened and ground shaft. If the shaft cannot serve as a raceway, order a suitable inner ring such as LR15X18X12,5 separately.
- Apply appropriate lubricant (grease or oil) during installation – refer to your equipment manual for viscosity specifications.
- Inspect the housing bore for wear or damage before installing the drawn cup bearing – the cup requires proper support for load distribution.
- When used with an inner ring, ensure the ring is fully seated and the assembly is correctly positioned within the housing.
