Stroke Bush Slide Rotary Bush [NB]
Stroke bush, slide rotary bush, linear + rotational motion guidance is also possible.
In addition to linear motion, it can perform rotational motion, is compact, and can withstand large loads. The wear-resistant holder is made of lightweight alloy and smoothly follows high-speed and high-acceleration movements.
basic information
The 【NB Stroke Bush】 has a structure that allows the balls in the retaining holder's through holes to rotate smoothly. The 【SRE Series】 has a structure that enables complex motion functions of linear and rotational movement without constraints, allowing for significant compactness compared to traditional methods that use separate bearings for linear and rotational motion. The 【RK Type】 adopts a retaining holder identical to the SR Type Stroke Bush, smoothly following high-speed rotational motion. The 【NB Slide Rotary Bush FR Type】 has a structure that enables complex motion functions of linear and rotational movement without being restricted by stroke limits.

Detailed information
-
Stroke bush A retainer, processed to arrange balls in a staggered pattern, is inserted into the precisely ground inner circumference of the outer ring, allowing the balls within the retainer's through holes to rotate smoothly. In linear motion, the retainer will move only half the length of its motion. The linear stroke of movement is limited to twice the range within which the retainer can move inside the outer cylinder. It is generally recommended to use 80% of the maximum stroke indicated in the dimension table as the movement amount.
-
The SRE type NB slide rotary bush features a cylindrical steel outer ring with an integrated retainer. The linear guide of the retainer is designed and manufactured to allow smooth circulation of the balls. Additionally, the retainer is structured to rotate freely in the radial direction, enabling smooth linear and rotational motion. There are 10 sizes available, ranging from φ6 to φ40mm. Three series are standardized: standard type, type with square flange, and unit type, to accommodate various mounting needs.
-
The RK type adopts a retaining element that is the same shape as the SR type stroke bush, allowing it to smoothly follow high-speed rotational motion. The linear motion part utilizes the SM type slide bush, providing stable linear movement. Additionally, it uses large balls, enabling it to withstand high loads.
