IKO Linear Bushing is a high precision linear motion rolling guide which travels along a shaft to achieve endless linear motion. In the external cylinder, a retainer, steel balls, etc. are compactly incorporated. Wide variations in size are available for selections suitable for each application.
Features:
Low frictional linear motion
Steel balls are accurately guided by a retainer, so low frictional resistance and stable linear motion can be achieved.
Simple replacement of conventional plain bushings
It is easy to use Linear Bushings instead of conventional plain bushings, because both types are used with a round shaft, and no major redesign is necessary.
Wide variations
For each dimensional series, standard, adjustable clearance and open types are available with and without seals, so the best linear bushing for the application may be selected.
Stainless steel type
Linear Bushings made of stainless steel are also available. This type is suitable for applications where corrosion resistance is important.

Linear rolling bearings
Linear rolling bearings are available as monorail guidance systems, track roller guidance systems, shaft guidance systems with linear ball bearings, flat cage guidance systems, guidance systems with linear recirculating roller or ball bearing units and as driven units (actuators and tables). Furthermore, INA also manufactures special miniature guidance systems for small design envelopes such as those in mechatronics and precision engineering. These very compact elements with very high load capacity, low friction and high rigidity are available as cage or recirculating systems. Due to their compact design, they can often replace solutions requiring significantly greater space.
Linear plain bearings
While in rolling bearing arrangements the bearing elements are separated by rolling parts (the rolling elements), in plain guidance systems the movable component slides on a static guideway or shaft. Depending on the type of guidance system, the sliding layer is applied to the movable or the rigid component. Lubrication is carried out by means of lubricants embedded in the sliding layer.

The TRCA series is a pre-engineered carriage assembly which has either SLBO or DLBO pillow blocks mounted to a 6061-T6 black anodized precision machined aluminum plate. The pillow blocks are doweled to the carriage plate and are pre-aligned to match LinTech's TRSA series shaft assemblies. The use of a TRCA carriage assembly and a TRSA shaft assembly in a mechanical positioning application greatly reduces the time consuming process of mounting & aligning two shafts and pillow blocks. Each carriage surface is precision machined which allows for accurate mounting of customer loads. Also, carriage assemblies are available with pre-machined stainless steel inserts, which allows easy mounting of customer loads to the carriage plate. Carriages are provided with pillow blocks for shaft diameters from 1/2 to 2 inches, and come in standard carriage lengths from 6 to 30 inches.

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 :

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.
