The secret you don’t know about ZYSL stud roller bearing!

ZYSL stud roller bearing is widely used in machine tools, industrial robots, electronic component equipment and OA equipment due to its high rigidity and stable precision as a follower bearing for cam mechanism and linear motion. The stainless steel ZYSL stud roller bearing has excellent corrosion resistance and is suitable for places that hate grease or environments where water splashes and clean rooms.

ZYSL stud roller bearing is a bearing with a rod end with needle rollers installed in the thick-walled outer ring. It is a low-friction row designed for outer ring rotation and has good rotation performance. The bearing can effectively increase the load range. , The radial clearance is designed to be smaller than the general needle roller bearing, so it can buffer the impact load and obtain a stable long life. Rod ends are threaded and stepped for easy installation.

ZYSL stud roller bearing C-Lube self-lubricating device is a lubricating part installed in the stud roller bearing. Since the necessary lubricating oil can be supplied to the outer diameter surface of the ZYSL stud roller bearing or the cam guide surface, it is not necessary to refuel regularly.
Although the load that ZYSL stud roller bearing can carry depends on the rated load of needle roller bearing, it is sometimes determined by the bending strength and shear strength of the rod end and the strength of the outer ring. Therefore, the maximum static allowable load is specified.
Guide load capacity refers to the allowable load that the outer ring of ZYSL stud roller bearing is in contact with the guide surface (plane) made of steel on the installation side, and the material of the installation side parts does not deform or indent and can bear continuously.

The load capacity of the slide rail is the value when the hardness of the other part material is 40HRC (tensile strength is 1250N/mm2). If the hardness of the other part material is different from 40HRC, the load capacity factor of the slide rail can be calculated by multiplying the value. In addition, if the lubrication between the outer ring and the opposite slide rail is insufficient, under certain working conditions, sometimes sintering or wear will occur. Especially when rotating at high speed such as stud roller bearing, it is necessary to pay attention to lubrication and surface finish.
