安装时需施加推荐的拧紧力矩才能保证轴承的技术特性。 |
Ball Screw Support Bearings
HRBN Ball Screw Support Bearing with high running accuracy and wide suitability, easy to install and debug, are used as support of various precision ball screw and there are kinds alternative structures. Angular Contact Ball Bearings, is composed of integral outer and inner ring, steel balls, cage assembly and sealing with rim angle of 60 degree. Axial rigidity is improved and it could be arranged DB, DF, DT or free. Axial Angular Contact Ball Bearings are made up of integral outer ring, split inner ring, steel balls and cage assembly with character of cramped construction and minute extension. and easy Installation and dwbugging, they can bear two-direction stress owing to their high running accuracy and they also can stand high radial load, as well as ceratin axial load. Needle Roller/Axial Cylindrical Roller Bearings are made up of needle bearings and roll bearings. It can bear bigger double axial load.
△Product accuracy: Dimensional tolerance and geometrical accuracy refer to GB/T307 P4. △Particular instruction: When
they are installed, exerting recommended strewing force moment secures
the technical characteristic of our products. |
