K89315-TV Axial Cylindrical Roller And Cage Assemblies, Double Row, Plastic Cage
The K89315-TV Cylindrical roller thrust bearings are specifically designed for applications requiring heavy axial loads and stringent positioning accuracy. Classic applications include heavy-duty vertical lathe tables, marine propeller shaft thrust devices, large gearboxes, wind turbine main gearboxes, rolling mill pressing mechanisms, and crane slewing bearings.
The K89315-TV bearing is a Axial cylindrical roller and cage assemblies, double row with an inner diameter of 75 mm , an outer diameter of 135 mm, a width of 11 mm. GCr15SiMn rolling mlement. Its dynamic axial rated load is approximately 283877 N, its static axial rated load is approximately 1007238 N. together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
K89315-TV bearings ( 75 mm x 135 mm x 11 mm) have the advantages of extremely high axial load capacity, high rigidity, compact axial structure, and a detachable design for easy installation, and are therefore widely used in the Machine tool worktables, extruders, differentials, wind power equipment, and oil drilling machinery.

The K89315-TV Cylindrical roller thrust bearings mainly consist of a shaft ring, a housing ring, cylindrical rollers, and a cage assembly. The rollers are arranged radially, forming a line contact load-bearing structure.
The advantages of cylindrical roller thrust bearings include extremely high axial load capacity, excellent rigidity, and a low coefficient of friction. Optimized roller end faces and flanges can accommodate slight eccentricity and impact loads, while also featuring a compact structure and high rotational accuracy.
