INA Axial-Angular Contact Roller Bearings are specially designed bearings that combine the features of angular contact ball bearings and roller bearings. They are capable of carrying both radial and axial loads and are suitable for high-speed and high-precision applications.
INA Axial-Angular Contact Roller Bearings consist of solid inner and outer rings, balls and cages. The inner and outer raceways are offset from each other in the axial direction of the bearing and have self-aligning capabilities. These bearings can be open or sealed. Open bearings have cut grooves on the outer ring for seals or dust covers, while sealed bearings are maintenance-free and are particularly suitable for economical applications. This bearing is suitable for applications that require both radial and axial loads, especially in high-speed and heavy-load applications. They are often used in mechanical equipment that requires high precision and high speed, such as high-speed motors, precision machine tools, etc. High load capacity: Capable of carrying large radial and axial loads. High speed performance: Suitable for use in mechanical equipment that runs at high speeds. High precision: Suitable for applications that require high-precision rotation, such as precision machine tools.
Self-aligning capability: Although the self-aligning capability is limited, it can adapt to slight misalignment of the shaft within a certain range.
Long-life design: Some models, such as the X-life series, have improved raceway shape and surface optimization, which increases the life by more than 50%
In the realm of high-performance machinery, where axial and radial forces converge and precision under load is paramount, INA Axial-Angular Contact Roller Bearings emerge as sophisticated engineering solutions. Representing a pinnacle of Schaeffler Group’s bearing technology, these specialized components are uniquely engineered to simultaneously support high axial loads, significant radial loads, and tilting moments with exceptional rigidity and running accuracy. Unlike pure axial bearings, they are true “angular contact” bearings in the thrust direction, offering unparalleled performance in demanding applications where space is constrained and misalignment is a challenge.
INA Axial-Angular Contact Roller Bearings represent a masterclass in solving complex load scenarios within demanding space and precision constraints. Their unique barrel roller design, combined with the self-aligning capability via sphered seat washers, delivers an unmatched combination of high axial and radial load capacity, exceptional rigidity, self-alignment tolerance, and superior running accuracy. Whether enabling the cutting precision of a CNC spindle in the ZARF configuration or providing ultra-compact, bi-directional support in a direct-drive motor with ZSL, these bearings are engineered for the most challenging applications across machine tools, robotics, automation, and high-tech industries. Backed by INA’s relentless pursuit of material science, precision manufacturing, and optimized internal geometry, they provide the robust, reliable, and precise foundation essential for next-generation machinery performance.
