Precision BiSlide Assemblies, for positioning and scanning, have dual 45 degrees opposing "V" ways to provide high rigidity in all directions. The carriage moves on low friction PTFE compound bearings, which are fully adjustable to customize pre-load. The Nylatron(TM)StabilNut(TM)lead screw drive nut is also adjustable. The second pair of "V" ways on the bottom side can be utilized should any damage occur to the top "V" ways.

Spring applied brakes
The MCNB Series spring applied brake incorporates a plastic armature, which significantly reduces the inertia that servomotors need to accelerate. This new, engineered plastic armature has friction material bonded directly to the surface. This material, designed to resist glazing, allows the brake to maintain a more consistent coefficient of friction over a wider temperature range. This allows the brake to have more consistent torque in high temperature servomotor applications.

Rolling ring actuators
This that its line of rolling ring linear actuators now offers users the ability to double axial thrust (up to 800 lbs. for some models) without going to a large size actuator. They achieve the doubling of axial thrust by adding an additional rolling ring bearing inside the actuator. The extra ring option eliminates the need to redesign to accommodate a larger drive shaft sized actuator and also saves on the associated costs.

Ball screw jack
This Ball Screw Jack features a ball nut with integral ball bearings that re-circulate along the surface of the ball screw. The reduced friction between the ball nut and screw results in greater efficiency. Compared to machine screw jacks, ball screw jacks reportedly require less motor horsepower, allow high screw speed, and provide an extended duty cycle.

This new Series 300 RAO interchange heavy-duty ball bearing incorporates double lip contact seals, Cam-Lock mounting, and other features to be well suited for agricultural, textile, and many other high capacity or high speed applications. They are designed as an exact interchange for other popular bearings used in these applications. The double lip contact seal is held securely by a snap ring, which prevents blowout during lubrication.

The ULTRA(TM)high-speed super precision bearing reportedly combines high speed capabilities with low internal heat generation while maintaining the precision, accuracy, and high surface finish of precision machined parts. With dimensions to ISO series 10, the ULTRA is dimensionally interchangeable with standard super precision bearings and, as a result, existing main spindle bearings can be easily replaced for higher speed capability.
