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,...

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.

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.
