Support roller (yoke-type track roller) with axial guidance (flange rings), lip seal on both sides
Support rollers (yoke-type track rollers) are designed to run on and to be used in cam drives, bed ways, conveyor systems, linear guidance systems, etc. They are based on a double row full complement cylindrical roller bearing with an inner ring and have a thick-walled outer ring with a cylindrical running surface. They are supplied sealed and ready-to-mount. The inner ring contains a lubrication hole to facilitate relubrication.
• High radial load carrying capacity
• Accommodate relatively heavy axial loads due to skew or tilting
• Long service life
• Ready to mount
• Sealed for increased reliability, with relubrication feature
