Empowering Future Manufacturing: NMT Robotics Bearings
The new era of industrial automation is defined by speed, precision, and flexibility. At the heart of every high-performance robot—from agile collaborative robots (cobots) on assembly lines to powerful six-axis arms in automotive plants—lies a critical component that determines its capability: the bearing. Standard bearings often fall short in these dynamic applications, where compact design, high rigidity, and zero backlash are not just desired, they are essential. NMT provides a comprehensive portfolio of bearings specifically engineered to meet the rigorous demands of the robotics industry, enabling the next generation of smart manufacturing.
Precision in Every Movement: Cross-Roller Bearings
The quintessential component for robotic joints, NMT's Cross-Roller Bearings are designed for applications requiring exceptional rotational accuracy and stiffness. By arranging cylindrical rollers perpendicular to each other on a V-shaped groove raceway, these bearings can withstand radial, axial, and moment loads simultaneously. This unique design allows for extremely compact and lightweight joint structures without sacrificing rigidity, making them the ideal choice for the rotary axes of industrial robots, precision rotary tables, and direct-drive (DD) motors.
Compact Power: Thin-Section Ball Bearings
Space and weight are at a premium in robotic arm design. NMT's Thin-Section Ball Bearings (including our N Series) offer an unparalleled solution. With a consistently small cross-section regardless of bore diameter, these bearings save significant space and reduce the overall weight of the robotic arm. This weight reduction is critical for improving the robot's payload capacity and energy efficiency. They are perfectly suited for shoulder, elbow, and wrist joints where compactness is paramount.
Unwavering Stability: Tapered Roller Bearings
For applications demanding the highest levels of rigidity and load capacity, such as the base of a heavy-duty robot or a precision machining head, NMT's Tapered Roller Bearings are the answer. Engineered to handle heavy combined loads, they provide the unwavering stability needed for precise and powerful movements. Their ability to be adjusted for minimal clearance ensures high system rigidity, which is vital for maintaining accuracy under heavy operational loads.
Seamless Integration: Bearing Units for Robotics
Simplifying design and assembly is key to accelerating innovation. NMT offers integrated Bearing Units for Robotics, which combine high-precision bearings with housings, seals, and mounting flanges into a single, ready-to-install module. These units, which can include integrated angle sensors, reduce design time, simplify the supply chain, and guarantee optimal performance out of the box. They are a perfect solution for manufacturers looking to streamline the development of new robotic platforms.
