SPECIAL BEARINGS
Wire Guides and Straightening Rollers
Field of Application: The straightening of cables, strips and wires is performed in steps with successive stages until the final product is obtained. To rationalize the handling between the different steps the material is stocked on reels or on bobbins and takes forms which are not natural.
For every production step, it is therefore necessary to carry out the inverse process by taking the material off its support. At that moment, the straightening operation takes place. It may be divided into three steps:
1) The straightening, consisting of putting the material back into its original shape. The operation is carried out by the first straightening rollers.
2) The removal of the residual constraint in the material, due to the winding on the bobbin. This operation is performed by the rollers located in the central part of the straightener.
3) The forming of the wire carried out by the last rollers on the straightener, generally placed at an angle of 90° compared to the angle of the first rollers.
Often it is necessary to combine these three steps. That is the reason why the straightener uses 5, 7, 9, 11 or even 13 rollers placed in two planes.
The manufacturing precision of the roller has a major influence on the quality of the final product (wires) as well as on the service life of the rollers. It is therefore essential that the rectified "V" notch on the outer ring has the same geometric characteristics and precision as the rest of the bearing. For this reason, the notch on a WIB roller is machined prior to bearing assembly.
Grinding this notch on an assembled standard bearing is risky, as the bearing may be damaged. An acceptable uniformity and geometrical precision can thus not be guaranteed. The service life of the roller is much shorter and the quality of wire drawing suffers accordingly.
Among numerous applications using thread guides and straightening rollers, WIB has managed to make a name for itself in the field of specialized wire drawing companies, producing steel cables for the tire industry.
The following machines use the same type of special rollers :
● Machine tools for fiberglass cables (lawn mowers)
● Machines for spring manufacturing
● Machines for metal wires
● Machines for spooling, un-spooling and rewinding
● Fine and high precision wire drawing
WIB is equipped with all the necessary tooling for the production of such bearings. The sales of some of these bearings are reserved to the designer of the system.

SPECIAL BEARINGS
Bearings for Linear Guide Systems
Field of Application: As a manufacturer of rollers for guidance systems (linear guides)WIB has worked together with customers on the development of several product ranges, supplying the best possible technical and commercial solution to each specific application. The parameters, such as the environment, the precision of functioning, the speed, the temperature, the load, the overturning moment, the boundary dimensions are decisive for defining the most appropriate design.
The above parameters require specific solutions, where the rollers are to be adapted by choosing the Variable Parameters described in the Standard Bearings section and theSpecial Options described in the Special Drawing Bearings section.
The following drawing shows an example of a roller with concave profile, integrated shaft and full complement ball bearing, specially designed for a guide system.
Profiles B, C, D and E may be machined on the outside diameter of the outer ring or on the bore of the inner ring. They are mostly used on rollers for guide systems for the following applications:
● Handling Equipment
● Robotics
● Machine Guidance Systems
● Automation Systems See Examples

SPECIAL BEARINGS
Bearings for Textile Machines
Field of Application: Textile machines are required to run at speeds which are regularly increased, and should be simple to maintain and economical to run. These requirements impose specific solutions, where the following parameters have to be optimized:
● Maximum speed
● Mounting and maintenance conditions
● Working precision
● Machine service life
● Loading Capacity
● Lubrication possibilities offered to the client
● Noise
● Protection against aggressive environments
● Weight
Only bearings specifically developed for each application will cope with the required specifications. With our wide experience in the field of choosing the Variable Parametersand the Special Options, WIB is in a position to offer the most appropriate solution.
The Examples shown on the following pages are the result of extensive development work and numerous trial runs carried out in co-operation with customers. It is through such joint effort that the quality of the final product has been improved to constantly meet the evolving market demand. All the Profiles have been used for textile machines.
Textile machines also use guidance and straightening systems with special bearings made by WIB and standardized bearings of the following types :
● Single row radial bearings
● Double row angular contact bearings
● Self-aligning ball bearings
WIB is equipped with all the necessary tooling for the production of such bearings. The sales of some of these bearings are reserved to the designer of the system.
