Overview

The crossed roller slewing bearing with internal gear is a high-precision rotary component designed for applications requiring compact structure, exceptional rigidity, and smooth rotational performance. The internal gear is machined on the inner ring, allowing seamless integration with drive pinions while maintaining a clean external appearance. This design is ideal for space-constrained equipment that demands reliable motion control under heavy loads.

Key Features

• High Rigidity – Crossed roller arrangement provides stable support in all directions, minimizing deflection under axial, radial, and moment loads.

• Smooth Rotation – Precision-ground rollers and raceways ensure low friction and consistent rotational accuracy.

• Internal Gear Design – Gear teeth are machined on the inner ring, offering a compact footprint and protection from external contaminants.

• Space-Saving Structure – Ideal for applications where external gear exposure is undesirable or space is limited.

• Durable Construction – Manufactured from high-quality bearing steel with heat treatment for extended service life.

• Integrated Seals – Built-in rubber seals protect against dust, moisture, and debris.

Applications

• Industrial robotics (welding robots, assembly arms)

• Medical equipment (CT scanners, surgical robots, patient positioning systems)

• Machine tools (rotary tables, indexing tables)

• Aerospace and defense equipment
