SEG Double X-roller Series
SEG 2-Roller Series
DOUBLE ROW X-ROLLER, EXTERNAL GEAR
Double row crossed roller, externally geared slewing rings offer higher radial and moment load capabilities than a similar sized ball bearing.
This makes them ideal for applications such as winches or heavy duty turnover jigs in which the dominant load is radial in nature.
The addition of an external gear facilitates the transmission of power.
