Installation tips of HONB YRT rotary table bearings

The YRT turntable bearing system can mainly be used in the CNC machine tool manufacturing industry. As its core component, the domestic market demand for YRT series bearings still relies heavily on imports from China. The precision parameter selection standards for domestic YRT turntable bearings are also based on international manufacturers. Since entering the 21st century, especially enterprises with the launch of our country's "High-end CNC Machine Tools and Basic Technology Manufacturing Process Equipment" special project, it has greatly promoted the development of my country's mechanical engineering equipment industry. "High-speed, precision, composite, intelligent The historical development process of the machine tool industry has been further accelerated by students. So how are YRT turntable bearings installed through analysis?

The bearing enters the housing.

The outer diameter of the YRT turntable bearing matches the bearing seat clearance.

Tighten the outer ring mounting screws in a criss-cross pattern.

The table surface of the CNC turntable is pressed against the end surface of the bearing.

The YRT turntable bearing can be installed as another part of the end face matching the flange.

Install the interference fit between the outer diameter and the inner diameter of the bearing.

Align the turntable bearings and mounting holes on the turntable.

Cross once and tighten the inner ring connecting screw.

The connecting screws penetrate the flange and the bearings are locked on the surface of the turntable.

If the bearing is extremely difficult to rotate, loosen the mounting bolts and retighten them in three steps in a cross sequence to eliminate bearing deformation.
