Robot bearings are specialized precision components designed to meet the rigorous demands of robotic systems, including high rotational accuracy, exceptional rigidity, and reliable performance in continuous operation. As a leading wholesale supplier of robot bearings, we offer a comprehensive range of high-quality products tailored for industrial robots, collaborative robots, robotic arms, and automation equipment, adhering to global industry standards such as ISO and DIN.
Our robot bearings are manufactured using premium materials, including high-carbon chromium bearing steel, stainless steel, and advanced ceramic materials. Combined with precision forging, vacuum heat treatment, and super-finishing grinding processes, these bearings achieve superior hardness (up to HRC 62-65), excellent wear resistance, and long service life. Key designs such as cross-roller structures and angular contact configurations ensure they can withstand radial loads, axial loads, and moment loads simultaneously, critical for the dynamic movements of robotic joints.
A standout feature of our robot bearings is their ultra-low friction coefficient and minimal noise emission (below 55dB), which is essential for reducing energy consumption and ensuring quiet operation in automated production environments. With high rotational accuracy (up to P4 class), they enable precise positioning of robotic arms, with runout and deflection controlled within microns. Our product range covers various types of robot bearings, including cross roller bearings, harmonic drive bearings, and angular contact ball bearings, with inner diameters ranging from 5mm to 300mm to fit different robot models and joint sizes.
Robot bearings are widely applied in industrial automation scenarios, such as automotive assembly lines, electronic component manufacturing, food processing, and medical device production. They are core components in articulated robots, SCARA robots, delta robots, and collaborative robots, supporting functions like material handling, welding, picking, and packaging. Additionally, our bearings are engineered to adapt to harsh working conditions, including high-speed rotation, frequent start-stop cycles, and dusty or humid environments, ensuring stable performance in demanding industrial settings.
As a trusted wholesale supplier, we provide competitive pricing, sufficient inventory, and fast global delivery for robot bearings. We offer customized solutions, including material customization, size modification, and special sealing designs, to meet the unique requirements of different robotic systems. Our professional technical team provides comprehensive after-sales support and technical consultation, helping customers select the optimal robot bearings and optimize their robotic system performance.
