STROKE BUSH E-1 STROKE BUSH SLIDE ROTARY BUSH

STROKE BUSH The NB stroke bush is a linear and rotational motion mechanism utilizing the rotational motion of ball elements between an outer cylinder and a shaft. It is compact and can withstand high loading. The retainer is made of a light metal alloy with high wear resistance. Smooth motion is achieved under high-speed and high-acceleration conditions. Although the linear motion is limited to a specific stroke length, the combined rotation and stroke motion is achieved with very little frictional resistance. The NB stroke bush can be conveniently used in a variety of applications. The...

SLIDE ROTARY BUSH SLIDE ROTARY BUSH SRE SERIES RATED LIFE AND LOAD RATING The rated life and load rating are defined as follows. The NB Slide Rotary Bush SRE Series provides rotary and linear motion functions. Linear motion with unlimited stroke and rotary motion are merged into a single bush resulting in great space saving compared with a combination of any conventional bearings. There are three types; standard, flange, and unit type with sizes ranging from 6 to 40. STRUCTURE AND ADVANTAGES Equation 1 gives the relation between the applied load and the rated life of the slide rotary bush....

Application Example 1 Vertical Shaft Robot Arm SLIDE ROTARY BUSH Since the ball elements rotate on the shaft surface in the SRE type slide rotary bush, the accuracy and hardness of the shaft are important factors. Outer Diameter: A tolerance of g6 is recommended for smooth Hardness: A hardness of greater than 58HRC is recommended for long life. If the hardness is less than 58 HRC, the life is calibrated using Surface Roughness: A roughness of less than Ra0.4 is An inner diameter tolerance of H7 is recommended Lubrication is needed (1) to prevent heat fusing by reducing friction between the...

SLIDE ROTARY BUSH 133033 NB's RK type slide rotary bush is a highly accurate and high load capacity bearing providing smooth continuous linear and rotational motions. Its structure imposes no constraints on linear and rotational motions. It is much more compact than a standard slide bush with separate rotational bearing. The RK type slide rotary bush uses a retainer similar to that used in the SR type stroke bush. This retainer gives a smooth motion in a high rotational SM type slide bush is incorporated, providing the stable and smooth linear motion. Relatively large ball elements are used...

SLIDE ROTARY BUSH FR/FRA TYPE NB Slide Rotary Bush FR type provides combined functions of linear and rotary motion without stroke limitation. Unlike the traditional slide bush, ball elements are arranged around the shaft within the inner space of a bush maintaining compact dimensions while providing high load capacity and high rigidity FR type is supplied as a set of a bush and shaft. Constructed with combination of a load carrying outer cylinder and a return cap, it is designed for smooth compound motions. For ease of mounting, the FRA type is also available, which has the FR bush...

NB Slide Rotary Bush FR type is manufactured with a properly controlled clearance between the shaft and the bush. When designing a custom housing, the recommended tolerance for the housing bore is H7 or H6. When rotational motion is involved anti-rotation tab option (Z) is recommended to prevent the bush from rotating within the housing. Please refer to Table E-6 for the recommended dimensions of housing when using the anti-rotation tab. FRA type is provided with anti-rotation tab as standard feature. recommended dimensions Ball Drop FR type is a set of a bush and shaft. Ball elements will...
