Cylindrical roller bearings are separable bearings with high load-carrying capacity, primarily designed to withstand radial loads. The rolling elements exhibit low friction against the raceway flanges, making them suitable for high-speed rotation. Available in multiple configurations, the linear contact between rollers and raceways provides exceptional load-carrying capability and maximum rotational speeds.

Product Description
Cylindrical roller bearings utilise cylindrical rollers as rolling elements and are classified as separable bearings. The linear contact between rollers and raceways enables substantial load capacity, primarily handling radial loads. Minimal friction between rolling elements and raceway shoulders facilitates high-speed operation. Multiple configurations exist, including N, NU, NUP, NF, and NJ types. Specialised optimisation delivers exceptional load capacity and rotational speed limits, suitable for fixed or floating end supports.
Product Features
- Multiple cage designs available, including nylon, steel, and brass cages.
- Optimised surface finish quality of rollers and raceways enhances operational reliability.
- Improved tolerance for misalignment between shaft and housing, ensuring extended service life.
- Cylindrical roller bearings exhibit high machining precision, with interchangeable separable rings.
- Linear contact between rollers and raceways delivers exceptional radial load capacity and rigidity.
