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.
NB SRE linear rotary ball bushing bearings are available in standard, flanged and pillow block unit-type configurations. Unlike the SR series of products, with SRE linear rotary ball bushing bearings, linear stroke isn’t limited by the length the retainer can travel. This allows for a more diverse set of potential applications, including robotic arms, gearing idlers in transportation equipment, tool changers and turntables. SRE series also are interchangeable with other NB products, including SM type linear bushings slide bushes, SMK type flanged bushings and more.
Features and Benefits At-a-Glance
SRE linear rotary bearings consist of a steel outer cylinder, an inner retainer holding a series of ball elements in place and a side ring. The retainer itself has been engineered to move freely in any direction, allowing for unlimited rotational and linear movement while keeping load distribution uniform while in operation.
NB SRE linear rotary bearings have many advantages over conventional bearing products, including:
Smaller Footprint
The ability to perform more functions while taking up less space is a key engineering concern in many industries. By combining linear and rotary movement functions in a single component, SRE bearings allow for smaller devices, lighter weights and fewer maintenance requirements.
