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.

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.

Adjustable precision guide bushes with optional wedging guide bushes “type SPIETH” are round of linear guiing devices for all ranges of the precise machine and building of devices. The employment of these guide bushes is indicated if the advantages of the slider, z. B. high absorption, to be used are and smallest guidance play one requires. Thus these guide bushes at Führungsgestellen, at round carriage guides, at headstock guides, at press tappets become etc. successfully assigned. Additionally to the linear movement also simultaneous rotating motion is possible. High acceleration values are unproblematic during according to arranged lubricant supply. The environment parts which can be made simply can be implemented in usual ISO tolerance. Existing adding play always permits an easy assembly, also when large dimensions. The demanded close guidance play is optimally stopped during the assembly procedure. Both small geometrical errors of the environment parts can, and operatingcaused influences, like e.g. arising higher temperatures, to be considered. With possibly arising wear a play adjustment is possible. The advantages in summary: - Inexpensive one, guide bush ready to be installed. - Easy assembly also when large dimensions. - The guidance play can be stopped during the assembly procedure. - Sliding friction in combination with precise guidance possible. - Simple connecting units which can be made. - For sliders typically high absorption available. - Accurate centric play restricting. - Fast disassembly facilitates machine service.

A new feature of the eccentric adapter bushing is designed to improve performance. Modern Linear adjustable bushings are designed with a knurled surface where the bushing contacts the carriage plate. This feature improves the holding ability of the bushing and wheel once it has been adjusted. Bushing slip is a leading cause of maintenance in this type of linear system.
Modern Linear adapter bushings are designed to replace existing bushings available in the marketplace.
New fasteners are in development to completely eliminate the possibility of wheels losing position during operation.

Eliminates Backlash, Reduces Friction
The NB Ball Spline is designed for mechanical applications which require both linear motion and torque transmission. The rolling contact of the balls eliminates backlash and reduces friction, helping you to achieve super precision and reliability.
The spline shaft facilitates additional machining and high accuracy because of a round shaft shape. Since the spline shaft is also machined by cylindrical grinding, it has a high sealing performance and a well-balanced structure that reduces the vibration and noise during rotary motion. Moreover, it has great geometrical moment of inertia and high rigidity. This enables a long-term, high precision linear motion.
