At high-speed speeds and high dynamics, high axial / radial forces occur, no play is tolerable here. For example, the mounting of the motor spindle shaft places the highest precision demands on the adjustability of the axial runout and the preload force. Here are self-adjusting nuts and clamping sets for Spieth used: zero backlash, high concentricity, positioning accuracy and stiffness that matters to every microns. For example, the concentricity of the clamping sets with an outer diameter of up to 80 mm is less than 8 µm. The axial application of the clamping force is converted into a uniform radial clamping force that is self-centering

2. Impact resistant and very rigid

Norelem now also offers support and locating pins in a version made from extremely resilient high-performance ceramics. They should have a significantly longer service life than bolts made from conventional materials. In addition, according to the company, they offer less wear, high abrasion resistance and temperature stability, as well as frequency neutrality. They consist of the material Cerazur, a metal-ceramic connection that is extremely impact-resistant and very rigid. The basis of this material is zirconium dioxide. In the company's product range, users will also find parallel pins, feather keys and guide bushes made of high-performance ceramics.

3. Configure and order brakes

ACE Shock Absorber GmbH extends the range of its online configurators.

Users can now find the ideal oil brakes and hydraulic brake cylinders for a variety of applications on the company's website. As with the other configurators that ACE already offers online as a provider of damping solutions, the new tool should also be easy and intuitive to use. As a result, the selection process takes place with just a few clicks and in a short time. Due to the connected online shop, the purchase of the appropriate machine element is only a further click away after the design.

4. Laser welded connections for more safety when transporting fuel

The Norma Group offers a new connector specifically for laser-welded connections. The SR-Quick-Connector-Laser-Welded is connected to the plastic pipe by laser radiation. The resulting connection is said to be about 30% more resistant and therefore even more reliable than mechanical connections. According to the manufacturer, it exceeds the applicable strength requirements of the SAE standard for connections in fuel lines.

The connector is particularly suitable for the demanding fuel lines in hybrid vehicles and other vehicles with a narrow engine compartment. From a certain temperature, conventional plug connections can no longer guarantee the usual strength and tightness. The laser-welded connection is said to offer greater security as it is particularly strong and resistant.

The interface of the connector to the pipe is shorter than with connectors with a fir tree profile and thus takes into account the limited space in engine compartments. Due to the welding technology, no additional O-ring is required. Due to the material savings, the connector should be more compact and lighter than comparable connectors.

The SR-Quick-Connector-Laser-Welded consists of laser-transparent thermoplastic. With laser welding, two materials are bonded together. Such a connection offers a higher tensile strength than mechanical connections by positive and non-positive connection. This means a more reliable connection, especially at temperatures above 150 ° C.

5. For optimal flow in central lubrication systems in the food industry

Chemie-Technik GmbH is expanding its range of Elkalub high-performance lubricants with a polyurea thickened silicone grease. The Elkalub GLS 762 / N0 grease was developed as an alternative to PTFE-thickened silicone greases especially for problem-free use in central lubrication systems. The trigger for the new development was a delivery problem in the automatic lubrication system of a well-known Bavarian brewery.

Until now, the use of polytetrafluoroethylene thickeners has been customary for the approval of silicone greases for the food sector. While PTFE is an excellent solid lubricant, its use with silicone oil can cause problems. Silicone greases that are thickened with polytetrafluoroethylene can separate under unfavorable conditions. Because of their high specific weight, the heavy PTFE particles separate from the lighter silicone oil. Such a grease separation can clog the line system in central lubrication systems.

Exactly this problem occurred at a Bavarian brewery a year ago: A PTFE-thickened silicone grease blocked a progressive distributor on the central filler carousel and threatened to shut down the filling plant.

Chemical engineering responded quickly with a new development: the silicone oil Elkalub GLS 762 / N0 does not require polytetrafluoroethylene and is equipped with a so-called NSF H1 registration for the food sector. The grease of NLGI class 0 was produced as a sample, the distributor was cleaned and repaired by the responsible customer advisor and the central lubrication system of the filler carousel was put into operation again. A year later, according to the manufacturer, the new grease shows no separations and the progressive distributor works without problems.
