13 series triple-row roller slewing bearing

Structural characteristics, performance, and scope of application
The three-row roller type slewing bearing has three races, and the upper and lower and the radial raceways are separated, so that the load of each row of rollers can be accurately determined. It can withstand various loads at the same time. It is the most load-bearing type among the four products. It has large shaft and radial dimensions and is firm in structure. It is especially suitable for heavy machinery requiring large diameter, such as bucket wheel excavator and wheel. Cranes, marine cranes, port cranes, steel running tables and large tonnage truck cranes.

(1)–Slewing bearing structure type 13: Three-row roller type
(2)–Transmission type code 

  • 0: No tooth type, 
  • 1: Small modulus external gear type 
  • 2: Large modulus external tooth type, 
  • 3: Small modulus internal tooth type 
  • 4: Large modulus external tooth type

(3)–The diameter of the upper row of rolling elements, mm
(4)–The diameter of the center of the upper row of raceways, mm
(5)–Installation type code

  • 0: Standard type without stop groove
  • 1: Standard type with a stop groove
  • 2: Special type

(6)–Mounting hole type code

  • 0: Inner and outer ring mounting holes are through holes
  • 1: Inner and outer ring mounting holes are screw holes
  • 2: Outer ring mounting holes are through holes, inner ring is screw holes
  • 3: Outer ring The mounting hole is a screw hole, and the inner ring is a through hole type designation.

For example: three rows of columns, small modulus internal teeth, inner and outer ring screw holes, the main raceway center diameter is 1600mm, rolling element combination 40/32/25, standard The type has a slewing bearing with a stop grove, the product type is marked as follows: Slewing bearing 133.40.1600.11 JB/T2300-99
