Crossed tapered roller bearings, also known as crossed roller bearings, are specialized bearings designed to provide high rotational accuracy and radial and axial stiffness. They are commonly used in applications where precise positioning and rotation are critical, such as machine tools, industrial robots, and rotary tables. Here are some key characteristics and features of crossed tapered roller bearings.
Crossed roller bearings have a unique design where cylindrical rollers are arranged in a crossed pattern between inner and outer rings. This arrangement allows for high rigidity and load-carrying capacity.
The rollers have tapered shapes, which helps distribute loads more evenly and accommodates both radial and axial forces.
The crossed arrangement of rollers provides high rigidity in both radial and axial directions, making these bearings suitable for applications with high precision and accuracy requirements.
Crossed tapered roller bearings often have preloaded or reduced clearance designs, minimizing backlash and improving positional accuracy.
The compact design of crossed roller bearings allows them to accommodate heavy loads in a small envelope, making them suitable for applications where space is limited.
