APTSURF™ Series High-Rigidity Double-Row Cylindrical Roller Bearings
APTSURF™ Series High-Rigidity Double-Row Cylindrical Roller Bearings
New materials in a new design enhance machine tool performance.
Features
- High speeds/low heat generation
An optimized design increases supported speeds and decreases heat generation. - Long life
Grease lubrication extends service life. - Stable rotation
A highly rigid PPS resin cage restricts deformation due to centrifugal force and keeps rotation stable at high speeds.
Standard Series Single-Row Cylindrical Roller Bearings
Standard Series Single-Row Cylindrical Roller Bearings
NSK's standard single-row cylindrical roller bearings conform to ISO standards.
Features
- Long-life materials
NSK's Z steel, a long-life bearing steel, is used as a standard material. - High rigidity
High-rigidity types use a roller-guiding machined brass cage.

NSKROBUST bearings feature a highly heat-resistant PEEK cage and heat/wear-resistant SHX steel to achieve a dmN value of 2.2 million.
Features
- Low heat generation
An optimized design achieves low heat generation. - High seizure resistance
SHX steel significantly improves seizure resistance. - Optimized materials for high speeds
Heat-resistant, highly rigid PEEK resin material realizes impressive high-speed performance.
FAQ
- What is the difference between using two single-row APTSURF bearings and using one double-row APTSURF bearing?
-
- Even when the have the same bore/outside diameter dimensions, the internal design and bearing width differ between single- and double-row bearings, so their catalog limiting speeds and load ratings also differ. Because of these variations, be sure to take the dimensions surrounding the bearing into consideration as well.
- What are the differences between the various series (APTSURF, NSKROBUST) of super precision cylindrical roller bearings?
-
- APTSURF bearings are designed for precision machinery at large, while NSKROBUST bearings are specialized for ultra-high-speed applications such as machine tools.
