Plain bearings and rolling bearings | Machine elements for movement

Here you will find the latest developments from all areas of warehouse technology, especially the Plain bearings and roller bearings. The Difference Between the two most commonly used bearings, the plain bearings, also bushings and roller bearings such as ball bearings, roller bearings or needle bearings, the following is the case: With plain bearings, the parts that move relative to one another are in direct contact. Sliding friction occurs, which can be reduced directly or indirectly through lubrication. In rolling bearings there are rolling elements between the inner ring and outer ring Frictional resistance and thus reduce wear.

Whether she is a bearings or Rolling Which you select for your application depends very much on the requirements of the application and its required properties, such as radial load or axial load, lubrication, acting forces, friction, speeds, wear, etc. The behavior is the same material selection of plain bearings or roller bearings or that of balls such as steel, bronze, sintered bronze, plastic, etc. relative to the application of the components.

There are completely stock out Ceramics or Hybrid bearingswhere only the rolling elements are made of ceramic. When storing a shaft, a distinction is made between the radial bearing, which can absorb radial forces, and the axial bearing, which absorbs axial forces. Plain bearings like to run out Plastic deployed. Such a Plastic bearings offers advantages in terms of service life or it usually requires little or no maintenance.

Counterfeit rolling bearings endanger people and machines

28.03.2023 | Schaeffler takes regular action against counterfeit products. The globally active Automobile- and industrial suppliers in Schweinfurt 30.000 Rolling Have copies with a total weight of 10 t destroyed. After scrapping, the material is melted down in a steelworks so that the steel finds its way back into the material cycle.

Precision roller bearings directly from the manufacturer: fast and flexible

Precisionstock for industrial applications reliably and quickly is a major challenge in times of supply bottlenecks. Good to be there with a partner like that Rodriguez GmbH works together. Flexible in-house production has been established here over the years. Rotary and linear components can also be delivered quickly to customer specifications.

From the tiny mini Rolling from a huge rolling bearing measuring several meters to a system solution: the portfolio Schaeffler Ball and roller bearings has solutions for every application - from machine tools, robotics and industrial automation to the food and packaging industry Wind Turbine or mobile work machines, just to name a few. These are getting stronger too digitized. Here we present the innovations:

The compactness and light weight of the Kaydon Thin section bearings not only meet the requirements of the robot age often better than conventional ones Bearing. With the slim all-rounders, which from Rodriguez are offered, space and weight of more than 80% can be saved in many applications - with high performance and precision. Here you will find new developments, information and applications for thin section bearings.

In the area of ​​precision bearings, the Rodriguez GmbH with their Kaydon “Realislim” Thin section bearingsn a key technology for the Aerospace available. These specialized rolling bearings contributed to the success of the Mars mission in 2021 by allowing NASA's Perseverance rover to carry out its tasks efficiently and reliably. The Precision ball bearings but are also suitable for other applications in the demanding industry.

About 250.000 manufacturers put the igloo bearings from Igus in their constructions. the Plastic-Plain bearings show their advantages wherever the construction between moving components has to be protected from wear caused by friction. The Motion Plastics specialist praises the every two years Manus Award 2023 which selects particularly interesting applications. Below we report on new plain bearings and unusual applications.

How to deal with high quality Machine elements In-house material flows designed more efficiently, knows Alexander Rubin, Product manager at Dr. Tretter in Rechberghausen. With an extensive program Ball Transfer Units users can move loads of different weights with ease. This portfolio also includes the Air Cargo series of heavy-duty ball transfer units, which are significantly lighter and more resilient than competitive products.

maedler0117In addition to the various roller bearings in the standard design, Mädler now also has ball and roller bearings in design C3 with increased internal clearance in its range. The size of the internal clearance is not a question of quality, but rather has to match the application. The most common rolling bearings have normal internal clearance. Rolling bearings in design C3 have a larger radial internal clearance.

A combination of radial and axial forces as found in modern day Machine Tools acts on threaded spindles, places considerable demands on the used Precision bearings. High axial rigidity and concentricity are essential here for exact tool positioning and reliable repeatability. For that offers Rodriguez an extensive range of rolling bearings, including the double row axial angular contact ball bearings DRF.

tretter1118The ball bushings from Dr. Tretter together with ground shafts form a precise linear guide without stroke limitation. The manufacturer offers a wide range of different variants - in cylindrical and flange designs or integrated in housing bearing units. Designers can do a lot with it linear guidesolve tasks cost-efficiently.

MisumiIn special machine construction, the components are required in application-specific designs, the smallest batch sizes and at economic conditions. Misumi meets this need with a portfolio of mechanical machine elements from over 40 product groups that is looking for its equal. The article describes in particular the ball bushing program with its innovative lubrication technology and the range of plain bearings, which are suitable for a wide variety of applications.

Franke has its in the course of miniaturization Wire race bearings of the LER type around the bearing element LER 1.5 im Miniature format added. It offers the most space-saving installation space in the competition for the small, compact and lightweight Rolling. The new wire race bearing also scores in terms of preload.

Igus also calls it "Slip dry“: The storage of shafts or axles in the Linear Technology and Drive Technology. As with all camps, the principle of action is basically between the two types Sliding and rolling bearings distinguished. While ball bearings are often still preferred as the measure of all things, thanks to innovative high-performance plastics there is an ever-increasing number of applications which Linear bearings speak.
