While the NB stroke bush has a limited rectilinear traveling stroke, it works with minimal wear resistance and enables smooth linear/rotary complex motion. It can therefore be used with a variety of devices.
The NB stroke bush is designed to allow the ball bearings to rotate smoothly. The finely ground outer case contains a retainer which forms a staggered arrangement of the steel balls in machined holes on its inner surface. Each ball in the retainer may rotate smoothly in its individual hole while the outer case moves in a rotary and/or rectilinear reciprocating motion.

Well known as A-bearings, these all-steel bearings are the original precision anti-friction linear ball bushing bearings offering the following features:
* A coefficient of friction as low as .001. When replacing high friction plain bearings, Precision Steel Ball Bushing bearings dramatically improve machine productivity and efficiency.
* All-steel construction, for maximum system rigidity.
* Two accuracy classes allowing for immediate improvements in system positioning and repeatability.
* Availability in fourteen bore sizes and nine configurations.
* The RoundRail* Advantage minimizes installation time and cost.
* Steady state travel speeds up to 10 ft/s and accelerations to 450 ft/s2 without the use of derating factors.
* An operating temperature up to 600 degrees F.
* Availability in a self-aligning pillow block housing for ease of installation and use.
* Worldwide availability from over 1800 authorized distributors.

The NB slide bush is a linear motion mechanism, utilising the rotational movement of ball elements. It can be used in a wide variety of applications, including transportation equipment and semi conductor production equipment.
The NB stroke bush is a linear and rotational motion mechanism utilising the rotational motion of ball elements between an outer cylinder and a shaft. Smooth motion is achieved under high-speed and high-acceleration conditions. The NB stroke bush may be conveniently used in a wide variety of applications.
The NB slide rotary bush is a highly accurate rigid component providing smooth continuous linear and rotational movement. It is much more compact than a standard slide bush with separate rotational bearings

These bearings are used in lower load applications where self alignment is not required. The precision fit between the bearing and shaft is built into the bearing as a result of the solid steel shell. These bearings utilize a molded plastic bearing ball retainer assembled inside a hardened and ground shell.
- Designed for use on end supported PowerTrax™ HG “L” shafting.
- Solid steel shell, no seals.

Optimum Performance Greater Accuracy
The NB Slide Shaft was developed to achieve greater accuracy in roundness, cylindricity, surface finishing, and linear travel. Heat treated in both axial and radial directions, NB Slide Shaft come in both high-carbon chromium bearing steel or Martensite stainless steel for maximum performance quality. In addition, our precision machining capabilities offer you a variety of specially engineered custom shafts, such as spindle and roll shafts, to meet your special requirement.
Accuracy
NB Slide Shafts feature reliable, high precision roundness cylindicity, straightness, and surface finish. Fig. 1 and 2 show examples of measurement results for roundness and surface finish, respectively.

The NB slide shaft is used with bearings such as the slide bush in order to obtain highly accurate linear motion.
When used in combination with a slide bush, the shaft performs as the inner race of the bearing system.
The NB slide shafts are manufactured with an emphasis on quality and accuracy to ensure stable functionality under many operating conditions. Superior performance is guaranteed for both rotational motion and combined rotational and linear motion.

Unlike gears, splines only apply the transmission of power on the same axis. In Arrow’s products, most splines are used on shafts and internal diameters of gearing for the purpose of mounting.
Arrow’s size range and capabilities for Splines are provided in the table below.
Maximum Pitch Diameter – 20”
Diametral Pitch – 4/8 – 80/160
Face Width – 13.0
Unground Tooth – AGMA Q9
Ground Tooth – AGMA Q13

Eliminates Backlash, Reduces Friction
The NB Ball Spline is designed for mechanical applications which require both linear motion and torque transmission. The rolling contact of the balls eliminates backlash and reduces friction, helping you to achieve super precision and reliability.
The spline shaft facilitates additional machining and high accuracy because of a round shaft shape. Since the spline shaft is also machined by cylindrical grinding, it has a high sealing performance and a well-balanced structure that reduces the vibration and noise during rotary motion. Moreover, it has great geometrical moment of inertia and high rigidity. This enables a long-term, high precision linear motion.
