Application Case of Crossed Roller Bearings in SCARA Robots

2025-03-17

Selective Compliance Assembly Robot Arm (SCARA) robots are widely used in assembly processes. These robots feature three rotational joints with parallel axes, enabling precise positioning and orientation within a plane. This design makes them lightweight and highly responsive, operating several times faster than conventional articulated robots. Similar to a human arm, SCARA robots can reach into confined spaces for tasks such as moving and placing objects, making them ideal for industries including plastics, automotive, electronics, pharmaceuticals, and food. Their primary functions include part handling and assembly.

Axis Characteristics: The first and second axes have rotational capabilities, while the third and fourth axes can be customized according to specific needs, featuring either rotational or linear movement.
Operational Range: The unique shape of these robots determines their operational range, which resembles a sector-like area.
Size and Capacity: SCARA robots come in various sizes, with common working radii ranging from 100 millimeters to 1000 millimeters, and payload capacities between 1 kilogram and 200 kilograms.

Given the requirements for lightweight and high-speed response, the harmonic reducers used in SCARA robot joints must offer low friction torque, high precision, and long wear-resistant life. Beining Technology’s SHF series crossed roller bearings are specifically designed for use in harmonic reducers across various types of robots, including those manufactured by Harmonic Drive LLC. For example, an automation company uses SHF25 harmonic reducer bearings in the axis joints of SCARA robots, which are suitable for SHF series harmonic reducers.

Key Points:

Performance and Efficiency: Crossed roller bearings play a crucial role in ensuring smooth operation, high precision, and durability.
Applications: They significantly enhance the functionality of SCARA robots in automated manufacturing processes.
Industry Impact: These bearings contribute to the versatility and reliability of SCARA robots in diverse industrial settings, supporting tasks that require high accuracy and speed.
