Detailed information
Spherical roller bearing with relubrication features
Spherical roller bearings可承受双向较大的Axial载荷。这种Bearing具have自调心功能，能承受不对中和轴挠曲，而friction或Temperature几乎不会Superior升。design具have补充润滑的特点。可用于模块化系统中，包括Bearing seat、安装套和液压nut
Accommodate misalignment；High load carrying capacity；Relubrication features；Low friction；Long service life；Increased wear resistance
