The linear recirculating bearing are produce in economic for standard application and for precision application.
The linear recirculating bearing are composed by a cylindrical outer ring, by a cage that retains the balls, by two end rings to retain the cage and/or, when required, contact seals.
All of the components are designed and assembled to optimize the unit performance.the outer ring is suitably hardened to provide the longest possible life expectancy.
The cage made of steel, stainless steel or engineered resin, depending upon the type of bearing selected, provide the retention and allow the proper recirculation of the balls.
Characteristics of linear bearings :
1. High rigidity
- Linear bearings with steel outer ring offer high rigidity due to the large number of balls in contact. The units can be supplied with a steel cage and, when low weight is required, with resin cage.
2. Easy of assembly
- The standard units can carry load in every direction. The large variety of housing units and shaft supports allow simple and easy mounting.
3. Ease of replacement
- These units follow internationally recognized boundary and are therefore dimensionally interchangeable with competitive units.
Replacement due to wear or damage is quick and simple.
Linear bearings can be supplied in the following versions :
- Closed type
- Open type
- Flanged type
- Double and triple type, with and without flange,
- Center mount flange type,
- In steel, stainless steel,
- Self aligning,...

Linear system - Linear ball bearings
Characteristics
1. Compact design
Our linear ball bearings carry out integration on the most reduced space from 4 to 6 lines of balls, from where a high degree of accuracy of bearing under request for all the orientations of load.
2. Maximum loading of use
We guarantee a load of higher maximum use by the exclusive use of nanomaterials of authenticated quality and by a technique of advanced manufacture.
3. Maximum precision
The optimal play ensituation of work is one of the most delicate points for the use of the linear ball bearings. We bearing units are delivered with exact borings and tolerances.

While the NB stroke bush has a limited rectilinear traveling stroke, it works with minimal wear resistance and enables smooth linear/rotary complex motion. It can therefore be used with a variety of devices.
The NB stroke bush is designed to allow the ball bearings to rotate smoothly. The finely ground outer case contains a retainer which forms a staggered arrangement of the steel balls in machined holes on its inner surface. Each ball in the retainer may rotate smoothly in its individual hole while the outer case moves in a rotary and/or rectilinear reciprocating motion.

The NB slide bush is a linear motion mechanism, utilising the rotational movement of ball elements. It can be used in a wide variety of applications, including transportation equipment and semi conductor production equipment.
The NB stroke bush is a linear and rotational motion mechanism utilising the rotational motion of ball elements between an outer cylinder and a shaft. Smooth motion is achieved under high-speed and high-acceleration conditions. The NB stroke bush may be conveniently used in a wide variety of applications.
The NB slide rotary bush is a highly accurate rigid component providing smooth continuous linear and rotational movement. It is much more compact than a standard slide bush with separate rotational bearings

These bearings are used in lower load applications where self alignment is not required. The precision fit between the bearing and shaft is built into the bearing as a result of the solid steel shell. These bearings utilize a molded plastic bearing ball retainer assembled inside a hardened and ground shell.
- Designed for use on end supported PowerTrax™ HG “L” shafting.
- Solid steel shell, no seals.

Well known as A-bearings, these all-steel bearings are the original precision anti-friction linear ball bushing bearings offering the following features:
* A coefficient of friction as low as .001. When replacing high friction plain bearings, Precision Steel Ball Bushing bearings dramatically improve machine productivity and efficiency.
* All-steel construction, for maximum system rigidity.
* Two accuracy classes allowing for immediate improvements in system positioning and repeatability.
* Availability in fourteen bore sizes and nine configurations.
* The RoundRail* Advantage minimizes installation time and cost.
* Steady state travel speeds up to 10 ft/s and accelerations to 450 ft/s2 without the use of derating factors.
* An operating temperature up to 600 degrees F.
* Availability in a self-aligning pillow block housing for ease of installation and use.
* Worldwide availability from over 1800 authorized distributors.

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.

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) .
