Track roller guidance systems are linear guidance systems that can be compiled according to a modular concept for a wide variety of applications. Due to their lightweight construction, they are highly suitable for use in handling systems. They are particularly characterised by quiet running, high traverse speeds, long displacement distances and the modular concept.
Carriages
Track roller guidance systems comprise one or more aluminium carriages, profiled track rollers and a straight or curved guideway. Carriages are available as hollow section carriages, open carriages, compact carriages and bogie type carriages for curved, oval and circular guidance systems.
Guideways
Guideways consist of an aluminium rail with shafts made from rolling bearing steel rolled into the sides. The guideways are available in many different designs, e.g. guideways with a solid profile, hollow section guideways, flat guideways, guideways with a slot etc. Selection depends on the puropse to which the track roller guidance system will be put.

Offers a perfect solution for cage creeping probme by a built in rack + pinion mechanism with high accuracy.
Also you could use this product in vertical axis applications where you could not use the existing Crossed Roller Guies easily due to creeping when you stop the machines. Dimensions are compatible with commercially popular crossed roller guides. Recommended applications are measurement machines, inspection machines and wafer processing machines.

Compact Rail has all of the characteristic that distinguishes Rollon’s entire product line:
compactnees, smooth movement, and ease of use. The “T + U” and “K + U” rail systems can be mounted on non-machine surfaces and can even compensate for mounting surface parallelism inconsistencies. This flexibility allows the design engineer to focus more time and energy on the application itself and not on the components while saving large amounts of mounting time and, therefore, money. All Compact Rail sliders have radial ball bearings rollers, which provide smooth and fast movement.

| Crossed rollers add 6-8 times greater capacity than ball slides. Can withstand loads in any direction. |

Rexroth Cam Roller Guides have been specially developed for use in materials handling and automation technology applications.
They stand out thanks to their high permitted maximum speeds, compact design, extremely low weight, simple installation and low friction.
Their extremely quiet running performance represents yet another advantage.
The user can obtain each element as an individual item, if required. |

The innovative linear system of the T-Race Family is setting new standards in the world of roller-based linear systems and telescopic rails. Thanks to the outstanding design of raceways and sliders with the possibility of self-aligning (principle of guiding and loading slider) with only one type of raceway the T-Race system offers many advantages of storekeeping, construction and economy.
Typical applications for cam roller units are for example machine doors, tool changers, handling systems and high quality drawers.
The roller-based system is available in raceway sizes 18, 28 and 43 mm. By combination you can build different variations, for example telescopic rails.
Advantages of the T-Race roller-based system:
• Roller-based system with improved load capacity
• Self-aligning system with adjustment of the preload
• Easy assembly, compensating of assembly/structural errors
• Acceptance of radial and axial loads
• Only one type of raceway (guiding and loading slider)
• Hardened and corrosion resistant surface
• Comparable load capacity with smaller size
• Self-lubricating system for all sizes
• Sliders with 3 or 5 rollers
• Low friction

Castor guidance
Particularly for applications with those it on small friction and small noise arrives the new castor guidance SG and OSG was developed.
The execution SG offers a particularly compact building method, since the castors run in a channel from aluminum with inserted hardened waves. The load-carrying capacity of the system can be changed thereby by the number of castors.
The execution OSG possesses a base from aluminum with inserted hardened waves. The castors are outside employed with this design.
The castors can very sensitively be employed and so the running properties excellently to application be adjusted by the eccentric execution of the castor axles.
The rails are manufactured in 4 m length and can be shortened depending upon need or also built up. When desired the waves can be manufactured also from rust-steady material.
Typical applications for these linear guidance with castors are packaging machines, sliding doors and simple economical linear units with small loads.

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.

IKO Crossed Roller Way is a linear motion rolling guide in which a roller cage is incorporated between two ways with V-shaped raceways. As the cylindrical rollers are alternately crossed, Crossed Roller Way can receive loads in any direction and can achieve very smooth linear motion with very high accuracy. Wide variations in size are available for selections suitable for each application.
Features:
Standard type and module type
Two types are available: the standard type and the module type. In the standard type four ways and two roller cages are used as one set, while in the module type two inner ways are integrated into a single piece.
Very smooth operation
Precisely finished raceways are combined with roller cages, in which the length of super precise rollers is accurately controlled to avoid skewing. Very smooth linear motion with very little frictional resistance and free from stick-slip can be achieved.
High carbon chromium bearing steel type and
stainless steel type
Standard types include high carbon chromium bearing steel type and stainless steel type.

GUIDANCE HAS ROLLERS
SHOES OF GUIDANCE
The shoes of guidance to rollers have a steel induction hardenings structure and rectified, provided with four circuits of recirculation to rollers. These systems are used in the event of load very
raised.
Sealing:
The whole of the shoes of guidance to rollers are delivered with seals of sealing:
- seals of end (seal scraper),
- lower seals,
in order to increase the lifespan by preventing dust, the chips,... to be introduced inside the shoe.
Lubrication:
A lubricator is provided with the whole of the shoes of guidance. The standard localization of the lubricators on the whole of the shoes of guidance is at the ends. However for certain types of assemblies the lubricators can be assembled on the side of the shoe, to specify at the time of the request.
RAIL OF GUIDANCE
All our rails of guidance are out of tempered steel and rectified, they are delivered either in standard length, or put at length and are chamfered, and accompanied by shutters for the clamp holes.
It is possible to have an important length by carrying out a junction (rails of end to end put guidance). |
