Due
to the self-alignment function, the balls run without difficulty into

this means that the bearings can achieve higher loads and a longer operating

Linear bearing |
Linear
ball bearings and plain bearings are also available in conjunction
with INA housings as complete bearing units. The linear
bearing is located in the housing ╳ |
The
housings are made from a high rigidity, high strength ╳ |
Due to the comparatively low total mass, the units are particularly suitable for reduced mass designs with high loads and where higher accelerations and travel speeds are required. |
Threaded
or counterbored holes in the housing ╳ |
For rapid alignment, the housings have a locating edge. This also prevents distortion of the linear bearings when the housings are being mounted. |
Centring holes allow rapid additional location by dowels on the adjacent construction. |
The housings are available in closed design, with a segment cutout and in open, slotted and tandem versions (with and without a centring collar). |
In
this variant, the bearing and housing ╳ |
Open designs with a segment cutout are used where, in the case of long guidance systems, the shaft must be supported and the bearing arrangement must be highly rigid. |
The
tandem version contains two linear bearings. As a result, the units have particularly
high load ╳ |
Tandem

For
special applications, there is also a tandem version with a centring collar

As a result of volume production in large quantities, the complete units are normally considerably more economical than customers’ own designs. |
The
bearings are available in an open version and with contact seals ╳ |
Due
to the initial greasing with a high quality ╳ |
Linear ball bearings can be lubricated, depending on the design, via the openings in the outer ring or radial holes arranged in the centre of the bearing. |

The housings are available in a closed design, with a segment cutout for supported shafts and with or without a slot. In designs with a slot, the radial clearance can be adjusted by means of an adjusting screw. |
All series have a locating edge and centring holes for dowel holes. |
