Rotary table large hollow bores are high-precision mechanical components that play a crucial role in various industrial applications. They are designed with a hollow shaft center, allowing materials or tools to pass through the axis, facilitating diverse functions such as wiring, pneumatic tubes, or rods passing through the gearbox.

Rotary table large hollow bores rotary tables are often used in applications requiring high accuracy and high torque. They have features like low cogging torque, direct drives, integral bearings, and encoders, making them suitable for machines operating conveyors and similar equipment.

Variants such as those offered by Tallman Robotics, equipped with crossed roller bearings, boast high positioning accuracy, excellent runout characteristics, and significant axial force capabilities, making them excellent for precise positioning applications like mounting positioning tables, end-of-arm-tooling (EOAT), or pick-and-place grippers.

Models such as the TMN feature an 85 mm hollow bore diameter, integrated planetary gearboxes, and optimized motor mounting systems, making them highly versatile for mid-size tables and end-of-arm tooling.

Rotary table large hollow bores are integral to achieving high precision in industrial automation, providing flexible and powerful solutions for a range of applications from simple positioning to complex multi-axis machining.
