INA Linear Bearings are bearing elements for translation type motion. As in the case of rotary bearings, a distinction is drawn as to whether the forces occurring are transmitted by means of rolling or sliding elements.

INA Linear Rolling Bearings

INA 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). In addition, INA makes miniature guidance systems for use in mechatronics and precision engineering applications. These elements are compact with a high load capacity, low friction and high rigidity and are available as cage or recirculating systems.

INA guidance systems comprise a guideway/carriage unit, a linear bearing/shaft system or are guideway/guideway units with roller or ball flat cages between them. INA driven linear units are single-axis or multi-axis complete systems with a mechanical guidance system, an electric motor and a controller matched to the system.

INA Linear roller bearing RUS and flat cageINA linear guidance systems are ready-to-fit locating bearings mainly for unlimited stroke lengths. Flat cage guidance systems and linear guidance sets are, with a few exceptions, used for restricted stroke lengths due to the cage kinematics.

INA Monorail Guidance Systems

INA monorail guidance systems are compact linear guidance systems with high rigidity and load carrying capacity, supplied in complete form as standard and based on either rollers or balls. These guidance systems can support loads from all directions – apart from the direction of motion – and moments about all axes. They are available in various accuracy and preload classes and are therefore suitable for applications with high guidance and positioning requirements.

INA Roller Monorail Guidance Systems

INA Linear recirculating roller bearing and guideway assemblies RUE are, due to the use of cylindrical rollers, the INA monorail guidance systems with the highest load carrying capacity and rigidity. They comprise at least one carriage with a full complement roller system, a guideway, integrated elastic wipers on the end faces of the carriage, sealing strips on the upper and lower faces of the carriage and closing plugs to close off the fixing holes in the guideway.

INA Monorail Guidance SystemsINA Ball Monorail Guidance Systems
  • INA Six-row linear recirculating ball bearing and guideway assemblies

Six-row linear recirculating ball bearing and guideway assemblies KUSE are the ball-based guidance systems with the highest load carrying capacity and rigidity. They comprise at least one carriage with a full complement ball system, a guideway, integrated elastic wipers on the end faces of the carriage, sealing strips on the lower face of the carriage and plastic closing plugs.

  • INA Four-row linear recirculating ball bearing and guideway assemblies

Four-row linear recirculating ball bearing and guideway assemblies KUVE are the most versatile and comprehensive range of monorails from INA. These units comprise at least one carriage with a full complement ball system, a guideway, integrated elastic wipers on the end faces of the carriage, sealing strips on the upper and lower faces of the carriage and plastic closing plugs.

  • INA Two-row linear recirculating ball bearing and guideway assemblies

Two-row linear recirculating ball bearing and guideway assemblies are the economical alternative where guidance systems with moderate load requirements are concerned. The units comprise at least one carriage with a full complement ball system, a guideway, integrated elastic wipers on the end faces of the carriage, sealing strips on the lower face of the carriage and plastic closing plugs.

INA Miniature Ball Monorail Guidance SystemsINA Miniature Ball Monorail Guidance Systems
  • Two-row miniature linear recirculating ball bearing and guideway assemblies

These guidance systems are preloaded linear locating bearings for limited and unlimited stroke lengths. These have moderate load carrying capacity and moderate to high moment load carrying capacity.

  • Four-row miniature linear recirculating ball bearing and guideway assemblies

Four-row miniature linear recirculating ball bearing and guideway assemblies are ready-to-fit guidance systems for unlimited stroke lengths. They have high to very high load carrying capacity and rigidity.

INA Linear Ball Bearing Units

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.

INA Linear plain bearings

INA Linear DriveIn INA 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.

Linear plain bearings are linear locating bearings for unlimited stroke lengths. These linear guidance systems are available as a miniature plain guidance system, INA linear plain bearings and INA linear plain bearing units as well as a flat guidance system. INA plain bearing guidance systems have low wear and high static load capacity, are insensitive to shocks and contamination, make little noise and operate substantially free from stick-slip. Maintenance-free plain guidance systems do not require lubrication, and low-maintenance materials have good emergency running characteristics.

INA Linear Roller Bearings

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.

INA Linear Recirculating Bearings

The linear roller bearings are available in a design in which the cylindrical rollers are separated from each other by spacers, a full complement version and an angled version element. The design with spacers runs particularly smoothly and quietly and is sealed on its end faces. Full complement linear roller bearings are suitable for high temperatures, speeds and accelerations. Angled elements are particularly suitable, due to the 90° arrangement of two linear roller bearings, for closed arrangements. This design is sealed on all sides.

INA Linear Recirculating BearingsINA Linear Roller Bearing Guideways

Due to their high precision, the guideways in conjunction with the linear roller bearings give high precision linear guidance systems. They are made from through hardened rolling bearing steel, have precision ground raceways and are available as a single piece up to the maximum length. Longer guideways are made up from matched sections. The guideways are supplied in grades Q2, Q6 and Q10.
