ORT Rotary Table Bearings – Detailed Product Description
The ORT rotary table bearing series is a precision-engineered bearing unit consisting of a thrust race, a radial race, a thrust gasket, two needle roller and cage assemblies, and a set of centripetal cylindrical rollers. Screw holes are provided on both the race and the ring to facilitate easy and secure mounting onto the machine structure.
ORT series bearings offer exceptional performance characteristics, including:
High axial rigidity – ensuring stable positioning under thrust loads
High radial load capacity – capable of supporting significant radial forces
High stiffness – minimizing elastic deformation under combined loads
High accuracy – suitable for precision motion control applications
These features make the ORT series ideal for use in demanding rotary applications, such as:
High‑precision numerical rotary tables
Indexing heads (dividing heads)
Direct drive motors (DD motors)
Vertical grinding machines
Gear hobbing machines
Other high‑precision machine tool and automation equipment
Available Models (Standard Range)
We currently offer the following ORT series models:
ORT50, ORT80, ORT100, ORT120, ORT150, ORT180, ORT200, and ORT260.
In addition to these, many other models and custom sizes are available upon request. For dimensions, technical specifications, or any further information, please do not hesitate to contact us.
