Innovative rolling bearing technology for machine tools
The materials to be processed place very diverse requirements on main spindle bearing supports. The cutting forces during high-speed metal cutting are completely different than for wood or polyamide materials. The bearing technology also differs accordingly. Even for auxiliary units such as chip conveyors, tool changing systems, loading technology and feed drives , it literally pays off when procuring roller bearings to work together with a partner who on the one hand has the necessary application experience and on the other hand not only offers standard products in its range. Findling Wälzlager GmbH supports its customers in a wide variety of industries with sound consulting and with economically and technologically optimum products.
ABEG® in the machine tool industry
Varying cutting forces make other bearing technology possible. All high-precision bearings are costly solutions, especially since the production processes and the precision classes to be achieved for them require highly modern production technology. As a result, there still aren’t any competitive products available from China. However, things are different when it comes to auxiliary units. Feed drives, chip conveyors, and tool changing systems require a lot of bearing technology, and optimized bearing selection using ABEG® can have a significant impact on overall cost structures.
Application examples from the machine tool industry
Product recommendations for machine tools
Support bearings for screw drives: High precision and optimum performance
NACHI support bearings for screw drives were improved in order to meet new industrial requirements regarding high precision and high speeds. NACHI TAB-type support bearings for screw drives reliably and precisely support screw drives, for example in machine tools.
- High axial stiffness: Having a larger number of balls with a polyamide cage results in much higher stiffness compared to conventional angular contact ball bearings.
- Simple and compact: The contact angle of 60° enables the bearing to simultaneously bear the axial load and a certain amount of radial load. This characteristic makes a simple and compact design possible.
- High capacity and low noise level: The use of large balls allows even higher loads than the ones already achieved by NACHI having polyamide cages combined with high-performance grease for quiet running.
- Energy savings: A superior seal design delivers low start-up and rolling resistance and minimizes the loss of force.
- Easy installation: The pre-tensioning of bearings during series production eliminates the need for complicated adjustments during installation.
Deep-groove ball bearings for high speeds
You will find a lot of solutions specifically made for machine tools in Findling’s product range. Because of the high speeds involved here, spindle bearings, high-speed angular contact ball bearings, and cylindrical roller bearings, as well as Xspeed deep-groove ball bearings, are used. These products are suitable for main shaft bearing arrangements and for directly driven tools in milling heads for the timber industry. In-depth expertise in the selection of lubricants, precision classes, and roller bearing cages is particularly relevant in this area.
Spindle bearings – the best of both worlds
Maximum precision, stiffness, and robustness make spindle bearings from the ABEG® range an ideal selection for the machine tool industry.
Our international orientation allows us to offer both the European standards and Japanese high-precision bearing technology, both in premium quality.
Sealed precision bearings with grease for life are becoming more and more popular and are made possible by optimized lubricants with high speed characteristics. Excellent seals reduce start-up torque and a high-performance lubricant provides the necessary lubricating film, even at low speeds. These characteristics have a direct impact on service life and make cost reductions possible.
Special cage designs made of phenolic resin or glass fiber reinforced materials enable high operating temperatures and reduce centrifugal forces.
ABEG® eXtreme series
Findling Wälzlager’s special product range is divided into four series: Xforce, Xspeed, Xtemp, and Xclean. This allows different requirements to be met with respect to operating conditions. Xforce bearings are solutions for high loads at low rotation speeds in which there are unfavorable tribological conditions and lubrication film build-up cannot reliably occur with standard solutions. During the development of the Xspeed series, on the other hand, high speeds and energy efficiency were the focus. The Xtemp series ensures temperature stability in excessively hot or cold conditions. The Xclean series provides robust bearing technology for corrosive ambient conditions as well as special designs for clean room applications.
