Ladle turrets: Slewing bearings and their features
Triple-row roller bearings
- Roller bearings for ladle turrets are specifically designed to withstand demanding tasks
- With exceptional resistance to both axial forces and tilting moments, these bearings offer outstanding durability and reliability, ensuring optimal performance even in demanding operating environments
- Suitable for high temperature use: steel cages in combination with special sealings
Special sealings
- High temperature suitability: Specialized sealings for slewing bearings used in ladle turrets that are designed to withstand exceptionally high temperatures
- These sealings are perfectly suitable for the working conditions of ladle turrets, providing superior performance and reliability even in the most challenging operating environments
Pelletizing disks: Slewing bearings and their features
Triple-row roller bearings
- Important process parameters for pelletizing include the disc inclination and disc speed. Therefore, the roller bearings are designed to withstand various load situations under continuous rotation
- The gearing of roller bearings on pelletizing disks is hardened to minimize wear during the several million load cycles
- These bearings are highly resistant, ensuring exceptional durability and performance even in challenging operating conditions for several years of continuous use
System competence
- We offer a comprehensive range of components for pelletizing disks, including robust and durable drives, all from a single source
- By sourcing all your components from us, you can ensure seamless integration and optimal performance of your pelletizing disks application, while also benefiting from our commitment to quality and reliability
Bottle filling machines: Slewing bearings and their features
Cross roller bearings and single-row four-point bearings
- The bearings used in bottle filling machines are mounted play-free to ensure optimal performance
- High speeds greater than 50 rpm are no problem: the bearings are engineered with exceptional precision to provide smooth and accurate operation, ensuring the highest levels of quality and efficiency in the bottle filling process

Reduced service efforts and costs
- Solid lubrication: Liquid, heated polymer-oil compound, curing of polymer in the bearing
- Operating temperature: -40 to 100°C
- Suitable for food industry: NSF/H1-approval
- No re-greasing: Significantly reduced service efforts and cost
- No grease leakage and contamination of the environment
- Increased lifetime: No risk of raceway corrosion
Amusement rides: Slewing bearings, slew drives and their features
Tapered roller bearings
- Suitable for horizontal rotating axes (e.g. in giant wheels with high wind loads)
- Adequate for high load capacity and the ability to withstand both horizontal and vertical forces, in the case of giant wheels or other amusement park rides, this could include wind loads or other external forces that might be exerted on the bearing
- Optimal load distribution in fast-moving rides which is particularly important for ensuring safe and reliable operation
Slew drives
- Safety: Slew drives are ideal for amusement rides due to their compact and enclosed design ensuring utmost safety
- Possibilities: They enable both fast and slow rotations, precise position holding, pivoting, and maneuverability in rides like ferris wheels, roller coasters, rotating gondolas, and swinging attractions
Superfinishing
- Superfinishing, as an advanced method for machining the raceway surface of slewing bearings in amusement rides, can result in a longer calculated service life for high-rotation main bearings
- This process can also reduce inlet wear and provide a significant increase in material content due to its plateau-like surface structure, resulting in an enhanced performance and durability of the slewing bearings
Seamless hardening
- The use of seamless hardening in slewing bearings for amusement rides ensures that they can withstand the highest continuous loads
- As a result of the seamless hardening process, the bearings have longer runtimes and can operate more reliably and with reduced maintenance needs, enhancing the safety and performance of the amusement rides
Turntable ladders for fire trucks: Slewing bearings and their features
Single-row four-point bearings
- Turntable ladders for fire trucks benefit from ball bearings that are best suited for low to medium bearing loads
- Ball bearings function as level bearings offer excellent performance in fire ladder applications, ensuring reliable levelment and efficient operation
- Special, curved toothing for less wear possible
Machine tools: Slewing bearings and their features
Triple-row roller bearings and single row four-point bearings
Triple-row roller bearings and single row four-point bearings
- Accuracy due to play-free execution of the roller bearing
- To prevent excessive bearing temperatures, the raceway system must have low torque resistance, which is achieved through using rollers, a plastic cage, and precise seals
- Due to precise gearing with gear quality 10, there is a higher positioning accuracy and smoother running
