SIG Double x-roller Series
SIG 2-Roller Series
DOUBLE ROW X-ROLLER, INTERNAL GEAR
Double row crossed roller, internally 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 internal gear facilitates the transmission of power.
