About 646/A6420

High speed, high precision

High rigidity, impact resistance, vibration resistance

Can withstand large axial loads

Mainly suitable for bearing radial and axial combined loads dominated by radial loads, while large taper angle tapered roller bearings can withstand combined loads dominated by axial loads. Tapered roller bearings are separable bearings, and their inner components and outer rings can be installed separately. The radial clearance and axial clearance of the bearing can be adjusted during installation and use, and can also be installed with interference fit. Tapered roller bearings generally use steel plate stamping cages, and steel plate welded cages or steel pillar solid cages when the size is larger.
