Manufacturer profiles associated with Mounting hub.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
Bore concentricity is the most critical specification, as even minor eccentricity (typically >0.005 mm) can cause significant angular position errors in high-resolution encoders.
While some hubs are brand-specific, many follow standardized dimensions (particularly bore sizes and mounting patterns). Always verify dimensional compatibility and consider custom machining for optimal performance.
Material affects thermal expansion (matching shaft material minimizes stress), weight (affects rotational inertia), and electrical properties (insulating materials prevent ground loops). Aluminum offers the best balance for most applications.
