Applications
Sized for the machine, not for the catalogue
The same ring diameter can be right for a crane and wrong for an excavator. Duty cycle, shock load and environment decide the structure, the hardening depth and the sealing.
Six application groups
Solar & Renewable
Single-axis and dual-axis tracker drives sized for wind load, with IP65 housing and encoder options.
Construction Machinery
Excavator swing circles, truck crane rings, aerial platform turntables and pump truck booms.
Mining & Metallurgy
Stacker-reclaimer rings and ladle turret bearings that run continuously under heavy axial load.
Industrial Automation
Low-backlash cross roller rings and drives for rotary tables, robots and index positions.
Why application detail shortens the quotation
Two rings with the same diameter can differ by a factor of three in load rating depending on structure, hardening and clearance. With the application in hand we can pick the structure first and argue about price second — which usually makes the part cheaper.
- What the ring moves, and how often
- Shock or impact load during the cycle
- Indoor, outdoor, coastal or wash-down environment
- Expected service life in years or cycles
Tell us the machine and the duty cycle
Load, speed, rotation angle, environment and expected life are enough for a first proposal.
