U - profiles are hot-rolled from 18MnNb6 in lengths of up to approx. 12 metres. The yield strength is more than 400 N/mm². Significantly higher than that of a steel classification S355J2G3. Also, the tensile strength is increased to approx. 700 N/mm². profiles are aligned as standard and can also be finely adjusted with our CNC straightening machine to tolerances of 0,2 mm per metre at the customer´s request. On request, the profiles can be primed or flame galvanised. A complete processing of the profiles to the customer´s technical drawings and/or specifications can be arranged e.g. drilling, milling, welded elements.

We supply many, various profiles in fixed lengths, also in manufactured lengths (approx. 12 m)

U profile for use with the combination bearings and radial bearings for vertical and horizontal movements.

SHIM ADJUSTABLE COMBINED ROLLER BEARINGS. These combined bearings are adjustable by introducing shims between the hub and the axial roller carrier.
This enables the overall height of the bearing to be altered

These adjustable combined roller bearings have the side (axial) roller mounted on an eccentric shaft which allows for adjustment in their height

Adjustable combined bearings with eccentric pin have the same characteristics as adjustable combined bearings.

 

In this case, the adjusting of the distance is made through the rotation of the whole axial part (pin and little roll) in the central pivot.

Adjustable combined bearings with eccentric pin have the following technical characteristics:

The outer ring and the axial little roll are manufactured in case-hardening steel type 20CrMnTi.

This kind of steel guarantees a very good resistance to stress, and assures a very good resistance against crashes. The surface hardness can reach 60-2 HRC for both of them.

Inner ring and pin are manufactured in core-hardened 100 Cr6 steel. The total-hardening steel guarantees high resistance to wear and stress; both of them reach 60-2 HRC hardness value.

Originally used in fork trucks, combined roller bearings can be used in a variety of horizontal, vertical, cantilevered or telescopic linear motion applications.Combined Bearings are particularly suitable for truck lift columns and all other convoying systems which require profiles. They can afford load from both axial and radial direction at the same time.
