Crossed roller bearings play a vital role in modern machine tools with high speeds and high precision. We offer high-performance crossed roller bearings for critical applications such as CNC rotary tables, robot joints, and grinding machine spindles. Through innovative design and strict quality control, our products can effectively improve the machining accuracy, dynamic rigidity and service life of your equipment.
High rotational accuracy: our crossed roller bearings adopt a unique design of alternating roller arrangement, which can effectively eliminate axial and radial runout and ensure extremely high accuracy of machine tools at high speeds, making them an ideal choice for spindle bearings in precision machine tools.、Excellent load carrying capacity and rigidity: With optimized internal structure design, the bearings can simultaneously withstand multiple loads such as radial, axial and tilting moments. The high rigidity makes the machine tool remain stable during heavy cutting loads, significantly improving machining efficiency and surface quality.
Compact design, space-saving: the special structure of crossed roller bearings makes their size more compact than traditional combination bearings, which can effectively save the internal space of the equipment and simplify the design. This is especially important for the pursuit of miniaturization and integration of CNC rotary table bearing applications.
Easy to install and convenient maintenance: We provide standardized models and sizes, making the installation process easy and quick. Meanwhile, high wear-resistant materials and optimized sealing structure reduce maintenance frequency and cost.
CNC machine tool rotary table: High-precision crossed roller bearings can be used as the core rotary bearing of CNC rotary table to ensure indexing accuracy and repetitive positioning accuracy, which is the necessary choice for five-axis machining centers, vertical lathes and other high-level machine tools.
Industrial robot joints: In robot joints, crossed roller bearings can provide high rigidity and zero clearance rotary support, enabling the robot to maintain extremely high positioning accuracy in repetitive motion, suitable for applications with high load and accuracy requirements.
Spindles for precision grinding machines: Our crossed roller bearings can be used in the spindle system of precision grinding machines, and their high speed and low heat generation characteristics can effectively ensure the accuracy and stability of the grinding process.
