Cylindrical roller bearing small friction coefficient, remove the bento device

A, rolling body is a centripetal roller bearing cylindrical roller. The internal structure of cylindrical roller bearing by roller are arranged in parallel, with distance between roller stick to implement or isolation block, to avoid the mutual friction between roller tilt or roller, effectively avoid the increase of the rotary torque. Product parameters: the old model: 42505 eh thickness: 18 precision grade: P0 useless: engineering machinery types: roller roller samples or spot: spot roller number of columns: single use features: high speed stick to frame and its data: N bearing material: brass entities bearing steel cover gasket: no seal, cylindrical roller bearing features: 1. Roller and raceway for the line contact or offline contact, radial bearing ability big, applies to accept heavy load and impact load. 2. Friction coefficient is small, high-speed, right limit speed close to the deep groove ball bearings. 3. N and NU type axial move, can suit for heat shrinkable provoked or device error of shaft and the shell of the relative position changes, can be at ease use end bearing. 4. On the shaft or hole processing request higher, bearing assembly after the outer axis relative deviation should be kept under strict control, so as to avoid formation of contact stress concentration. 5. Inner ring or outer ring do not to facilitate installation and removal of four, cylindrical roller bearing features: cylindrical roller and race is line contact, radial load to big. Applies to accept heavy load and impact load, also suitable for high speed rotation. Cylindrical roller bearing raceway and rolling body geometric shape. After improvement of design, has the high load-carrying ability, guard and roller end face of the new structure design, not only improved bearing axial load bearing ability, at the same time improve the roller end face smooth condition of contact with the rim area, the use of improved bearing performance. Five, the cylindrical roller bearing radial clearance adjustment way: commonly used boxes full of cylindrical roller bearing radial clearance adjustment method is as follows: 1, about the circular and elliptical bearing clearance can use manual crapping or bearing in faceted padded turning after repairing the way to adjust. 2, about the tip clearance can adopt manual of circular and elliptical bearings crapping or when conditions allow for bearing faceted padded way to adjust. 3, about more than oil wedge fixed axle bush, the criterion on are not allowed to repair and adjust bearing clearance, clearance when inappropriate, should change new tile. 4, about more than oil wedge tilting type bearing, are not allowed to fix the tile, clearance should be changed when not appropriate for the segment. Segment of thickness is adjustable, can be adjusted through behind the tile under the block and stainless steel pads, or thinning adjust the thickness of the block to adjust the amount of watts. Looking for more oil wedge tilting type bearing, group between tile thickness error should be less than 0. 01mm。
