Bushing ball - Import export

These bushes are ideal for easy and quick positioning of ball lock pins and locking pins. Advantages: centred by the centring collar. easy and reliable installation. can be screwed into various materials. usable both sides

The V shape of the shaft support is the result of purposeful internal development work at Föhrenbach. The most important advantage comes from having the greatest possible distance between the shafts and above all in the lay-out of the four ball-bearing housings whose loadbearing rows of balls are located underneath the shaft. The unitized, modular type like design realized with these devices enables to cover a wide range of application specific solutions. Manufactured in standard widths from 75 to 425 mm and in lenghts of up to 4000 mm, the products are designed to provide solutions that allow to cover almost all handling and mounting tasks that need to be met. An experience of long standing assures for competent solutions.

When the positioning cone and bush are mated, the balls are pressed together within the rubbers elastic range and thus locate the two parts in which they have been fitted, with maximum accuracy. To ensure that the rubber in which the balls are embedded is deformed within the elastic range, one must merely ensure that the depth of the hole into which the positioning bush is later pressed is precisely observed. The positioning cone is supplied ready to fit into the positioning bush and must simply be fitted into the counterpart component. Henceforth, a precise zero point positioning system is in place.

MPS Microsystems is specialized in manufacturing high-precision, miniature linear bearings. We offer a comprehensive range of exceptionally smooth bearings with bore diameters from Ø 2 mm to Ø 6 mm. The balls of these precision bearings meet ‘Grade 3’, the highest quality defined by the ISO 3290/DIN 5401 standard. Combined with a cage and a high precision casing, they allow rapid positioning while reducing friction and eliminating the stick-slip effect. The standard version of MPS Microsystems linear bearings consists of a stainless steel bushing and balls, and a brass cage. An all-stainless steel version or one with ceramic balls can be made on request.

MPS Microsystems offers a wide range of linear bearings that provide smooth movement. Another advantage of these guidance systems: their attractive price. They are available in a range of diameters from Ø 3 mm to Ø 25 mm and are made of injected plastic segments (POM), as well as easy-to-clean stainless steel needles and balls. The needles have three roles: they hold the segments together, they serve as external tracks for the balls, and they define the diameter of the ball bushing. The plastic segments of MPS Microsystems DBL series linear bearings enable their use in environments with high temperature fluctuations.

Manual positioning table drived by lead screw Guided by 2 rods on bronze bearings or ball bushings Precision manual tables The guidance is ensured by 2 rods on 4 calibrated bronze bearings (reduced play) or 4 ball bushings for guidance without play. The guide length of long body tables (309L/M) allows to accept large loads and torques. The axial positioning accuracy of these tables is <0.15 mm (in practice 0.02 to 0.10 mm). But the blocking in position is done on the carriage, by pressure on a guide rod, so as to remove the axial play of the nut of the trapezoidal screw after blocking. Manual crossed tables XY or YZ For the creation of XY crossed table, the tables are mounted one on the other directly by the body (long body version only) with the option 308922 * making smooth holes in the body of a table. To combine 2 tables in YZ, it is preferable to use a lifting table for the Z axis, mounted by its end on the body of the horizontal table.

Pneumatic cylinder double acting Guided by 2 rods on ball bushings or bronze bearings Elastic damping at end of stroke Magnetic piston and Tgroove for sensor Robust and precise compact cylinder with guide Long and precise guidance because even for very short strokes, guidance is ensured by 4 bronze bearings or 4 ball bushings as the shortest body is the 50 mm stroke for lower strokes, a stroke limiting ring is placed in the cylinder. This guidance avoids the problems of buttressing, regularly encountered with ultrashort guides. These pneumatic cylinders are robust and reliable, even at high speed thanks to screwed cylinder’s covers (no circlips) an hardanodized body at 35 μ a thick front plate allowing a long centering of the rods for a better resistance to torsion Guided cylinder for universal detector The 5 / 6.5 mm Tslots allow the use of the majority of brands of magnetic detectors on the market.

Hydraulic shock absorber on this table A hydraulic shock absorber may be placed in opposition to the pneumatic cylinder to dampen, for example, the descent and/or limit the stroke at the output of the cylinder rod. The retracting stroke can be adjusted by the floating rod coupling. Use in harsh environment For dusty environments, additional nitrile or polyurethane scrapers can be added in front of the ball bushings. An anticorrosion version can be proposed with the rods, the coupling and the screws in stainless steel (the carriage and the plates remain in anodized aluminum).
