Designing something new? We will engineer it.
Much of what we build is designed for one customer's machine. Our engineers size slewing rings, drives, pinions and gears around your loads, space and production volume, with no engineering charge.
- Sizing, load and life calculations, and FEA support
- 2D drawings and 3D STEP models for your design review
- Prototypes, then blanket orders and scheduled releases for production
- Engineered and supported in Hudson, Ohio
