The Turnback . 1313 and other international standards as required. Rollers bearing housing ensures that the TIR achieved on these rollers is incorporate a sealed for life bearing and seal assembly that is extremely low. designed for optimal sealing and lowest possible drag. Rollers are manufactured to SANS 1313 standards which determine size and performance standards. Alternative standards such as CEMA or DIN can also be referenced where required.

5 Roller design of shell diameter, shaft diameter and bearing specification is determined by the load experienced by the roller to ensure that the shaft deflection at the bearing is within the limits as specified by bearing manufacturers. Rollers can be manufactured in any variety of face lengths with a variety of contactless sealing system hermetic sealing system For lowest drag and breakaway mass Optimal drag with superior sealing. The seal is a multi-labyrinth The seal is a multi-labyrinth system. The contactless design system with the addition of a gives an extremely low running lip-style contact seal to provide resistance.
