The main reasons for premature failure of YRT turntable bear

Writer: admin Time:2022-09-23 11:59 Browse:

YRT bearings have suitable axial and radial load bearing mechanisms. High tilt stiffness and extreme precision for rotary tables, chucks and iron cutter heads as well as bearing arrangements in measurement and experimentation.
Applicable fields:
Mainly used in high-precision CNC turntable, indexing head, military radar, aviation, aerospace and the fields of measurement and testing that require high precision.

However, due to some incorrect use and operation methods, the YRT turntable bearing is damaged prematurely, causing some unnecessary losses.

Improper installation method
Use brute force during installation, and directly hitting the bearing with a hammer will cause the greatest damage to the bearing; it is the main cause of deformation.
The installation is not in place, the installation is deviated or not installed in the bearing position, resulting in the bearing clearance being too small. The inner and outer rings are not in the same center of rotation, resulting in different centers.
Improper lubrication method
According to the survey, poor lubrication is one of the main reasons for premature failure of YRT turntable bearings. The main reasons include: not adding lubricant or lubricating oil in time; not filling lubricant or lubricating oil in place; improper selection of lubricant or lubricating oil; incorrect lubrication method, etc.
Bearing contamination
Contamination can also cause premature damage to the YRT turntable bearing. Contamination means that sand, metal chips, etc. enter the inside of the bearing. The main reasons include: prematurely opening the bearing package before use, causing pollution; unclean working environment during installation, causing pollution; unclean working environment of the bearing, pollution of the working medium, etc.
Fatigue damage of YRT turntable bearing
Fatigue damage is a common damage method for YRT turntable bearings. Common causes of fatigue damage may be: long-term overload operation of bearings; failure to maintain in time; improper maintenance; equipment aging and so on.
