INA Linear bearing and housing units are available in the compact, light, heavy duty, machined and plain bearing range
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 by means of a radial fixing screw to prevent axial displacement.
The housings are made from a high rigidity, high strength aluminium alloy that allows the full load carrying capacity of the bearings fitted to be utilised. In the machined series, pressure diecast housings are also available.
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 velocities are required.
Simple location
Threaded or counterbored holes in the housing allow straightforward screw mounting on the adjacent construction, if necessary from below.
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 of the housings by dowels on the adjacent construction.
Housing designs
The housings are available in closed design, with a segment cutout and in open, slotted and tandem versions (with and without a centring collar).
Closed design
In this variant, the bearings and housings are closed. As a result, high precision standard guidance systems with a fixed enveloping circle can be easily achieved.
With segment cutout
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.
Slotted design
Closed designs and designs with a segment cutout are also available in several series with a slot. Slotted variants are suitable for clearance-free or preloaded guidance systems. The operating clearance is set by means of an adjusting screw.
Tandem design
The tandem version contains two linear bearings. As a result, the units have particularly high load carrying capacity.
Tandem ball bearing and housing units are available in open and closed designs. Both variants are also available in the named design with a slot.
