Double row cylindrical roller bearings have two structures: cylindrical inner hole and conical inner hole (bearing rear code plus K).

Advantage

Compact structure, small section, high rigidity, large bearing capacity, small deformation after loading (high radial load), and high rotation accuracy. The conical inner hole can also play the role of micro-adjustment of the clearance, and can simplify the structure of the positioning device and facilitate installation and disassembly.

Application:

◆ Gear transmission

◆ Cutting head scissors

◆ Rolling mills

◆ Machine tools
