Linear guidance systems with linear recirculating ball bearing units comprise ball bearing units, carriages and guideways. They allow large support distances, have adjustable clearance and are to standard accuracy class G3.
The full complement bearing units run on one or both sides of the guideways and, despite their small dimensions, have high load carrying capacity. If the bearing units are screw mounted in carriages, together with the guideways they form four-row linear recirculating ball bearing and guideway assemblies. The ball bearing units are sealed on all sides by the wipers on the end faces and on the sealing strips which form a gap seal in conjunction with the guideway. Linear recirculating ball bearing units can be relubricated.

Linear roller bearings are suitable in conjunction with guideways for locating/locating or locating/non-locating bearing arrangements and form a bearing arrangement system for linear motion with unlimited stroke length. In closed arrangements, they can support loads from all directions and moments about all axes. Their load carrying capacity is extremely high and the space required is very small. The guidance systems can be preloaded by adjusting gibs and have extremely high rigidity when preloaded.
Since the guidance elements have a versatile range of possible arrangements, linear recirculating roller guidance systems are suitable for numerous applications in general machine building, especially for linear guidance systems in machine tools where high guidance and positioning accuracies are required over long traverse distances.
The range is supplemented by adjusting gibs for precise setting of the preload, setting devices for measuring the deformation of the adjacent construction where preload forces must be supported and adapters for easy mounting of the linear roller bearings in a 45° arrangement.

BALL BREARINGS LINEAR RAILS are made of RUNNER that moves in a fixed RAIL.
Designed for load capacity from some kg to 600 kg PER RUNNER, the common length of the rail is 3 meters. It can be 5 meters for some references. Should some applications need very great lengths, the rails can be prepared for an end to end mounting.
Linear rails is the optimum solution for protective or access DOORS applications (machine tools, vehicles, trains or subways) .

Pacific Bearing Company proudly introduces our new line of cost effective, easy to specify linear guide systems—Integral V Technology. A unique, patent pending process allows for tighter tolerances without additional cost. The design itself is capable of carrying heavy loads at high capacity, velocity, and acceleration while still excelling in wear resistance. Integral V Technology also has a growing number of configurations and a wide range of uses with custom orders available.
With the 20 different configurations already available—and more being developed each week—the Integral V Technology is truly versatile in its application. Products in Integral V Technology include snap-In, bolt-on, integrated and compact configurations. All of which allow for easy installation, and what really sets this product and company apart from others, is that Pacific Bearing is willing to work with companies to integrate the technology into their extrusions. PBC’s engineering team is fully prepared to adapt or modify the customer’s base design with the new Integral V technology to ensure success within the application.
The hardened steel V-raceway allows for a high load capacity, rigidity and wear resistance. Our rail is constructed of light-weight aluminum partnered with hardened steel V-raceways that are mechanically inserted to create high contact loads and wear resistance; thereby lowering production and replacement costs. One of the most important features is the dramatic increase in system accuracy. With measurements taken down the entire 20’ section of the rail, current studies show the rails to be capable of holding ±0.001” from lot to lot and ±0.0005” within each lot!

Aerotech air bearings are perfect in semiconductor equipment, fiberoptics, photonics, and other critical industrial automation applications. Our air bearings incorporate an active preload on both vertical and horizontal surfaces. Opposing thin-film pressure maintains the bearing nominal gap tolerance. This design, in addition to the large air bearing surface that distributes the load over a large surface area, results in outstanding stiffness that is ideal for heavy or offset loading.

0 friction, life unlimited
The Airpel -AB provides "force without friction" which is made possible by a specially shaped stainless steel piston that is precisely fitted to a borosilicate glass cylinder. The introduction of pressurized air into the air bearing's cylinder creates a true air bearing airflow effect around the piston.
With as little as 5 PSI of air applied to the cylinder, the same air that drives the piston also produces a stiff cushion of air to support the piston and prevent it from contacting the cylinder wall.
The result is an air cylinder that delivers virtually unlimited piston life, no lubrication and clean operation. In addition, the output force of this friction-free air cylinder is reduced only infinitesimally by movement of ultra-low friction ball joints used to connect the rod. These unique qualities allow Airpot Corporation to guarantee that the Airpel -AB will exceed the life of any machine or instrument in which it is installed. Industries include, semi-conductor, optics, medical, and test and measurement.Applications may include, precise tensioning, positioning mechanisms supporting delicate materials, sensitive force control for holding or clamping fragile materials, counterbalancing and safety support for vertically positioned linear motor driven masses, or precise laboratory test equipment.
Airpel-AB air bearing actuators are available in metric models with four bore diameters and ten standard strokes to provide precisely repeatable driving or supporting forces from 2 grams to 58 kg. Operating temperatures range from -20 C to +90 C.
