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) .

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.

Product Overview
Recognized by engineers and industrial users for their long life, sleeve bearings are offered as an available option on all TITANÒ horizontal ODP, WP-I and WP-II enclosures. Sleeve bearings operate on a
thin film of oil supplied by oil ring or flood lubrication and are frequently applied to high(er) speed direct connected loads. Sleeve bearings have a very limited capacity for any external radial loads, but when applied and maintained correctly, they offer an infinite (theoretical) life.
U.S. Motors offers a unique sleeve bearing product when evaluated against the typical competitive design. The USEM two piece, spherically seated bearing has become an industry benchmark which provides significant advantages over the fixed seated bearing.
