Three Row Roller Bearing slewing rings SG13 series
?
S&G three-row roller bearings offer the highest capacity for a given diameter. When Other bearing doesn& acute;t meet your stiffness and capacity requirements, consider the SG13 series, usually used for radar, cranes, mining shovels, and other applications
?
Feature:
?
S&G13 series bearing has three independent rows of rollers oriented normal to the direction of loads being transmitted through the bearing. Their orientation is selected to optimize capacity, provide low frictional resistance and minimize deflection.
The top and bottom rows of rollers transmit any opposing thrust loads and combine to transmit any moment loading, while the middle row transmits any radial loads. The rollers, the separator configuration used for each, and the mating raceways are sized to meet load or other application requirements.
In order to obtain these performance benefits, the supporting structures must satisfy higher stiffness and lower flatness requirements than those for similar series bearings.
Gear teeth or other drive mechanisms can be provided on the inner or outer support ring, and the choice of hole pattern can be added for bearing retention.
# Note:
1. n1 is the nos of lubricating holes.Oil cup M10×1JB/T7940.1~JB/T7940.2.The Oil nipple& acute;s location can be change according to the user& acute;s application.
2. n-φcan change to tapped hole,the diameter of tapped hole is M,depth is 2M.
3. The tangential tooth force in the form is the max tooth force,the nominal tangential tooth force is 1/2 of the max one.
4. & quot;K& quot; is the trim top coefficient,outer tooth 0.1,inner tooth 0.2
Availability
S&G13 series series slewing ring bearings are custom manufactured to fit the design and specification.
?
Applications:
