Product Description

 

RB90070 Crossed Roller Bearing Introduction

RB90070 crossed roller bearing since the rollers are arranged in a cross, it can withstand loads in all directions with only one set of cross roller rings. Compared with the conventional model, the rigidity is increased by 3 to 4 times.At the same time, because the inner ring or outer ring of the cross roller bearing has a two-part structure, the bearing gap can be adjusted, and even if preload is applied, high-precision rotational movement can be obtained.

Product Processing

RB90070 Crossed Roller Bearing Product Grinding

Before grinding, it is necessary to formulate detailed processing technology according to the design size of the bearing, select appropriate materials and prepare blanks, and preheat or temper the workpiece to eliminate stress after rough processing and semi-finishing such as forging and turning. Then enter the grinding process, and perform precision grinding on the inner and outer ring raceways to achieve the dimensional accuracy and surface quality required by the design.

Product Testing

RB90070 Crossed Roller Bearing Product Testing

The cleaned RB crossed roller bearing is firmly clamped on the workbench of the three-dimensional coordinate measuring machine to ensure that the clamping is firm and does not affect the measurement. Using the manual or automatic measurement function of the three-dimensional coordinate measuring machine, according to the pre-planned measurement path, the probe slowly contacts the bearing measurement point to collect coordinate data. After the measurement is completed, the measurement software automatically processes and analyzes the data and generates a test report. The report covers detailed information such as the measurement value, tolerance range, deviation value, etc. of each test item, and intuitively displays the quality status of the bearing.
