Depending on whether the rings feature flanges, NSK cylindrical roller bearings comprise single-row types such as NU, NJ, NUP, N, and NF, alongside double-row types like NNU and NN. These bearings feature a separable inner and outer ring design. Cylindrical roller bearings without flanges on either the inner or outer ring permit axial relative movement between the rings, enabling their use as non-locating bearings. Cylindrical roller bearings featuring double flanges on one side of the inner and outer rings, with a single flange on the opposite side, can withstand axial loads in one direction to a certain extent. Typically, stamped steel cages or turned copper alloy cages are employed. However, some utilise moulded polyamide cages.
1. NSK Cylindrical Roller Bearings
Rollers and raceways engage via line contact or modified line contact, providing high radial load capacity. Suitable for heavy loads and impact loads.
2. NSK Cylindrical Roller Bearings
Low coefficient of friction, suitable for high speeds. Maximum operating speed approaches that of deep groove ball bearings.
3. NSK Cylindrical Roller Bearings: N and NU types permit axial displacement, accommodating changes in relative position between shaft and housing caused by thermal expansion or installation errors. They may be employed as non-locating supports.
4. NSK Cylindrical Roller Bearings: High precision is required for machining shafts or housing bores. After installation, any misalignment of the outer ring axis must be strictly controlled to prevent localised stress concentration.
5. NSK cylindrical roller bearings feature separable inner or outer rings, facilitating installation and disassembly.
