Bearing Units
Convenience and high reliability are achieved by combining ball bearing and bearing housing.
Since ball bearings for units have the same geometry as deep groove ball bearing, load rating, reliability, and other functions are equivalent to deep groove ball bearing.

Ball bearing units consists of pre-lubricated sealed ball bearings and a housing which varies in shape. They are capable of aligning themselves efficiently using the spherical fitting surface between the bearing and housing, effectively preventing overloads due to misalignment.
Koyo ball bearing units are highly accurate and feature excellent load resistance. They are completely sealed, and provided with a relubrication feature. Ball bearing units without a relubrication feature are also available.

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.
The full complement bearing units run on one or both sides of the guideways and, despite their small dimensions, have high load carrying capacity. If the bearing units are screw mounted in carriages, together with the guideways they form four-row linear recirculating ball bearing and guideway assemblies. The ball bearing units are sealed on all sides by the wipers on the end faces and on the sealing strips which form a gap seal in conjunction with the guideway. Linear recirculating ball bearing units can be relubricated.

Linear bearings offer an easy and economic solution for unlimited linear motions.
Three different types are available:
• Linear bearings with closed design for applications with short strokes and loads from different directions
• Linear bearings with slot and clearance adjustment
• Linear bearings with open design for applications with high and one-sided loads
Whole linear bearing units, partly with several linear bearings one behind the other and with different designs complete our product range.
There are linear bearings made of plastic with load bearing plates of hardened steel or linear bearings with steel body, in standard material or corrosion resistant, with or without sealing, in sizes 2 – 150 mm.
We certainly find the right linear bearing for your application.
Advantages of our linear bearings:
• Easy replacement
• Economy installing
• Self-adjusting for bended shafts
• Smooth running
• High speed applications with high acceleration

BALL BREARINGS LINEAR RAILS are made of RUNNER that moves in a fixed RAIL.
Designed for load capacity from some kg to 600 kg PER RUNNER, the common length of the rail is 3 meters. It can be 5 meters for some references. Should some applications need very great lengths, the rails can be prepared for an end to end mounting.
Linear rails is the optimum solution for protective or access DOORS applications (machine tools, vehicles, trains or subways) .

Track rollers are self-retaining, single or double row units with particularly thick-walled outer rings. These bearings can support axial forces in both directions as well as high radial forces. The bearing outer rings have a crowned or cylindrical outside surface. Designs with a crowned outside surface are used where there is misalignment in relation to the raceway and edge stresses must be avoided. The track rollers are available with an inner ring, with a stud and with a plastic tyre on the outer ring.

Traditional angular contact ball bearing measuring devices still use manual or semi-manual machines: a low degree of precision is obtained and the process time is long. The Bussi contact angle measuring machine is extremely precise, reliable, fully automatic and fast. It combines electronics with top-level engineering and pneumatics. It features:
Data setting: a computer stores the bearing data it is necessary to measure and is input just once. Every time there is a type changeover, only the bearing code needs to be recalled, thereby avoiding error and time wasting. Storage capacity: 500 types of bearing.
Automatic measurement: it makes two checks simultaneously, the contact angle measure and that all the balls are present. Field of measurement: 0° to 89.9°
Precision and repeatability: precise to ± 0.2 ° with high measurement repeatability. This performance can depend on the level of precision achieved when the bearing is constructed.
Measurement speed: the process is extremely quick, between 14 and 17 sec, with a capacity of up to 257 pieces/hr. Maximum type changeover: < 4 min
Optional automation for lines
