YRTC950-XL

The YRTC950-XL axial/radial roller bearing is a highly specialized and exceptionally rigid super-precision bearing designed for demanding applications, particularly in machine tool rotary tables, indexing heads, and other high-accuracy rotary axes. As part of Schaeffler's renowned YRT family, the "YRTC" designation indicates a combined axial and radial roller bearing with a sophisticated internal design to ensure superior performance. This specific "XL" variant often denotes an optimized X-life quality bearing, providing enhanced service life, reduced friction, and increased load carrying capacity compared to previous designs.

Key to its robust performance, the YRTC950-XL integrates multiple roller sets: two axial roller sets for supporting heavy axial loads in both directions, and a radial roller set for precise guidance and radial load support. This intricate arrangement allows the bearing to accommodate significant radial forces, axial forces from both directions, and tilting moments simultaneously, all without clearance. This "clearance-free" operation, often achieved through precise preloading at the factory, is paramount for applications demanding the highest levels of running accuracy and stiffness, preventing unwanted deflection and vibration.

The YRTC950-XL is also designed for straightforward screw mounting, with equally spaced fixing holes in both the inner and outer rings, simplifying installation into the adjacent structure. Its thick-walled construction contributes to its impressive rigidity, making it an ideal choice for direct-drive rotary axes where minimal deformation under load is critical for achieving optimal machining precision. Users can expect low and uniform frictional torque, which is particularly beneficial when integrated with torque motors, contributing to energy efficiency and thermal stability. This bearing is a testament to precision engineering, ensuring reliable and accurate motion in the most challenging industrial environments.
