High Accuracy Single Axis Supplier of actuator BG Type
NB's BG Type is a compact single axis actuator which integrates a Professional slide Guide and Precision Manufacturer of ball screw. BG Type offers compact dimensions, which outperforms conventional positioning stages. This is made possible by a unique "U" shaped Guide Rail and Slide Block which provides multiple functions of a Guide Block and a Ball Screw Nut combined into a single unit. The "U" shaped Guide Rail design offers a high rigid structure resistant to bending. This structural feature allows for integrated frameworks of machinery or equipment. Additionally, the Slide Block contains 4 ball circuits which delivers high load capacity, high accuracy and high rigidity.

Linear movement has traditionally required separate components to handle both drive and support/guidance. The patented Kerk® ScrewRail combines both functions in a single, coaxial component. By eliminating the need for external rail-to-screw alignment, the ScrewRail simplifies the design, manufacture and assembly of motion systems. The ScrewRails coaxial design saves as much as 80% of the space used by a two-rail system and is generally less expensive than the equivalent components purchased separately. The savings can be substantial due to lower component costs and reduced labor.
An added benefit is the ability to get three-dimensional motion from a single ScrewRail. When mounted vertically, the ScrewRail can be used to simultaneously lift and rotate (Z-theta motion). With one motor driving the screw and a second rotating the rail, a compact, self-supporting pick and place mechanism can be created.
The ScrewRail Linear actuator manufacturers consists of a precision rolled leadscrew, supported by sealed manufacturers of bearings and contained within a concentric steel guide rail, driving an integrated nut/bushing. Because all the alignment requirements are achieved within the ScrewRail, support and positioning of the ScrewRail is much less critical than with traditional slide assemblies. Kerkote® TFE coating and self-lubricating nut/bushing materials ensure long life without maintenance.

Rectilinear Motion Enabled With A Round Shaft
The NB Industrial slide Screw is a unique drive unit which makes efficient use of friction to convert rotary motion to linear movement. This unit is a very simple mechanism containing only radial bearings in contact with a shaft, providing ease of maintenance. Even if an accident occurs, this unit slips on the shaft, stopping itself to prevent further damage. The unit is applicable to a wide variety of devices by fully utilizing its features, although while accurate positioning would require an extra control.

The manufacturer of ball screw drive is used where high forces and precision at averagee speed is needed. The trapezoidal screw drive is used for applications with average requirements with respect to speed, force and precision and with a low operating factor. The toothbelt drive is preferably used for applications with high requirements to speed at average force and precision.
Features
Stroke lengths up to 11 m
Highly integrated technology allows to replace solutions with a large number of individual components
The torsion-resistant aluminium profile allows systems of high stiffness.
The patentpending self-adjusting sealing strip protects the drive
The patentpending screw supports at the ball screw drives allow high speeds also at high stroke lenghts
Extensive and optimized accessories

Joyce/Dayton - Established 1873
Joyce Ball screw jacks feature a ball nut with integral ball bearings that recirculate along the surface of the manufacturer of ball screw. The significantly reduced friction between the ball nut and screw results in greater efficiency, with up to 2/3 less input torque required to move the load than a similarly rated machine screw jack.
Compared to Machine Screw jacks, Joyce Ball Screw Jacks
- Require less motor horsepower
- Allow higher travel speed
- Provide an extended duty cycle
Joyce Ball Screw Jacks are available in translating screw or rotating screw (keyed for traveling nut) designs. Translating screws are available with threaded, load pad, clevis or plain ends. Options include limit switches manufacturers, professional encoders, geared potentiometers, direct drive and reducer mounts, and protective professional boots. Joyce Ball Screw Jacks are ideal for single or multiple jack systems.
Unlike Machine Screw Jacks, Ball Screw Jacks are not self-locking. Because they will lower under load, a braking motor or other external braking mechanism is required.

| Roller screw jack provide higher performance compared to ball screw jacks. Ideally suited to applications where a high dynamic load, high accuracy, high speed and a long life are required. |

This unit is able to fulfil the highest requirements for a wide range of applications. By entering the load and output into your customer system, the air supply system automatically and directly adapts to the given requirements. The frequency-controlled drive unit offers a wide control range with optimised demand matching. In addition to energy savings and higher efficiency, this also results in lower maintenance requirements. The non-contact, oil-free screw unit ensures high air flows with low pulsation and lends itself to "master/slave" operation. Integrated accessories include a non-return cock, intake industrial filter, sound absorbers and ventilation/bleed system. An air blast industrial cooler is also available.
