Ball Bearings

HIRT Linear Ball Bearings stand for customised play-free fit and maximum precision performance.Thanks to the individually manual lapping, honing and matching, they guarantee smooth operation with no stick-slip effect and impress with their exceptional durability. Preloaded Linear Ball Bearings are the optimal choice for cost-conscious designs in mechanical engineering, with a consistently high linear resolutions and excellent repeatability of up to 0.01 μ for the sensor finish guides. In addition to our extensive standard range, we also offer customised solutions - based on more than 30 years of experience in the development and production of Linear Ball Bearings.

Components for Linear Ball Bearings

Components for Linear Ball Bearings

HIRT linear ball bearings and components are synonymous with precision and are available both as complete units and as individual components – shaft, ball cage and housing. Each component is manufactured to the highest precision to ensure a customised, preloaded and backlash-free linear ball bearing offering high efficiency and long-term reliability.

Axial Bearings

Axial Bearings

HIRT axial ball bearings enable precise and reliable absorption of axial forces while ensuring smooth operation and low friction. They offer high load-carrying capacity and long service life and are ideal for applications in mechanical engineering and spindle systems. They offer high load capacity and long service life and are ideal for applications in mechanical engineering and spindle systems. Matching cages and counter discs ensure optimally coordinated and efficient bearing solutions.
