Looking for top crossed roller bearings manufacturers in the world? In this post, you will get enough informaiton.
Um rolamento de rolos cruzados é um tipo de rolamento de elementos rolantes de alta precisão. Utiliza rolos cilíndricos ou rolos cónicos dispostos alternadamente em ângulos rectos (num padrão em "cruz") entre um anel interior e exterior. Este design único permite que o rolamento suporte cargas radiais, cargas axiais em ambas as direcções e cargas de capotamento (momento) - tudo com um único rolamento compacto.
Antes de começar o blogue, queremos apresentar-nos como um fornecedor profissional de rolamentos de rolos cruzados na China. Se precisar de alta qualidade de fabricantes chineses, não hesite em contactar-nos.
1. THK

They are designed to fit into the exact same ultra-compact space as their ball bearings but offer significantly higher stiffness due to the line-contact of rollers. They also dominate the heavy-duty sector with their XR Series crossed roller slewing rings.
Best For: Upgrading existing thin-section ball bearing setups that require extra rigidity, as well as aerospace applications, radar mounts, and military turrets.

Fundada: 1899
Sede social: North Canton, Ohio, Estados Unidos
História: A Timken Company foi fundada por Henry Timken, que patenteou o rolamento de rolos cónicos em 1898, revolucionando a tecnologia de suporte de carga para carruagens e, mais tarde, para aplicações automóveis e industriais. A Timken tornou-se um líder mundial em rolamentos e produtos de transmissão de potência, adquirindo marcas como a Torrington (2003) e a Fafnir (1985) para expandir o seu portefólio. Com mais de 125 anos de história, a Timken opera em 42 países, com instalações de fabrico nos EUA, China, Índia e Europa, e serve indústrias como a automóvel, aeroespacial, ferroviária e maquinaria pesada.
Best Known For: Custom-engineered crossed roller bearings for aerospace, defense, radar mounts, and heavy mining equipment.
6. HIWIN (Taiwan)
Fundada: 1989
Sede social: Taichung, Taiwan
Visão geral: Hiwin Technologies Corp. was founded by Eric Y.T. Chuo in 1989, focusing on linear motion and control systems. The name “Hiwin” stands for “High Win,” reflecting its aim for high-quality precision engineering. Starting with ball screws, Hiwin expanded into linear guideways and actuators, becoming a major player in automation and robotics. It established global subsidiaries, including Hiwin USA (1993) and Hiwin Japan (1997), and has manufacturing facilities in Taiwan, Germany, Japan, and the USA.

Looking for a highly reliable, cost-effective alternative?
At ZMS Bearings Co.,Ltd, we don’t just sell components—we partner with mechanical engineers to solve complex rotational challenges.
Through years of supplying global industries, we deeply understand the critical pain points in your specific applications:
1. Industrial Robots & Cobots (Joints & Base Axes)
When a 6-axis robot arm is fully extended with a heavy payload, the moment (tilting) loads on the base joint are immense. If there is even a micron of play in the bearing, the tip of the robot arm will vibrate or sag. We understand the critical importance of negative clearance (preload). We customize the preload of our crossed roller bearings to ensure absolute zero-backlash, giving your robots the extreme stiffness required for precise, repeatable positioning.
2. CNC Rotary Tables & 5-Axis Machining Centers
In the machine tool industry, deflection is the enemy. When a milling machine is cutting heavy metal, the rotary table must withstand massive axial and radial cutting forces without yielding. We know that runout accuracy is everything. Our crossed roller bearings are precision-ground to achieve micron-level rotational accuracy, providing the ultra-high rigidity needed to ensure your CNC machines deliver flawless surface finishes.
3. Medical Scanners & Radar Systems
For CT scanner gantries and military radar tracking systems, the bearing must handle heavy loads while maintaining incredibly smooth, vibration-free rotation. We understand that fluctuating friction torque can ruin an image or a signal. That is why we focus on ultra-precision micro-finishing of our cylindrical rollers and raceways, ensuring whisper-quiet and perfectly consistent rotation.
4. The “Assembly & Space” Challenge (Why We use the RU/XSU Series)
We also understand the headaches of the assembly line. Designing a complex press-fit housing for a standard bearing takes up valuable space and adds weight. This is why we heavily support applications using the Mounting-Hole Type CRBs (like the THK RU or INA XSU series). By allowing you to bolt the bearing directly to your machine frame, we help you eliminate bulky housings, reduce overall weight, and drastically speed up your assembly process.
