Gros-Ite Spindle has been a trusted, highly-respected name in engineered products and assemblies, including premium spindles, since 1946.
They are not only known for Gros-Ite precision spindle design but their exceptional build and repair capabilities. EDAC/Grose-Ite Spindle has a global customer base, serving the aerospace, automotive, medical, industrial, commercial, and machine tool industries.
We are proud to welcome this enduring, highly-respected brand to our Superior Spindle family.
Gros-Ite Spindle Manufacturing
Gros-Ite Spindle utilizes high-precision off-the-shelf bearings in their variable preload system. That mitigates the physical liability of angular contact type of bearings.
The preload is varied to ensure optimal operating capacity. As a result, it minimizes vibration while maximizing spindle stiffness.
They have also developed a patented composite material spindle, housing, and shaft insert for optimal performance. Benefits include:
- Reduced weight of the spindle
- Reduced static deflection at the nose
- Reduced thermal axial expansion
- Increased static and dynamic stiffness
- Increased vibration dampening
- Improved critical speed range
One of the standout products Gros-Ite developed is the Holo-Rol™ Bearings. These feature hollow cylindrical rollers preloaded in the bearing instead of solid rollers.
Holo-Rol™ Bearings are leveraged for a wide variety of machine tool spindles or workhead spindles and have been used for over two decades in centerless grinders.
They provide several advantages over regular bearings, such as:
- Higher speed capability
- High radial stiffness
- Very low radial runout
- Vibration damping
