For example, the NTB Series has been used in everything from injecting glue onto chips in the semiconductor industry, to serving as a valuable design solution for medical design and device applications.
Using Kerk's patented take up mechanism, the NTB series maintains axial stiffness while system torque is held to a minimum, providing smooth operation and long life throughout its load and speed range.
The NTB series assembly has eliminated the need to highly preload the nut to compensate for load.

In addition, the NTB Series does not force manufacturers to increase device size, as the NTB is designed to fit in tight spaces and ensures optimum manufacturing efficiency.
The nut is manufactured with a self-lubricating polyacetal designed to run efficiently on Kerk's precision rolled shafting.
The screws are 303 stainless and are available with Kerk's proprietary long-life Kerkote coating, which eliminates the need for external lubrication and maintenance.
The NTB series are available with a triangular flange, round flange or thread mount and can handle a dynamic load of up to 200 lb.
The assembly is available in a variety of diameters and lengths.
