Solid One-piece Inner And Outer Ring Structure

AUBEARING manufactures CRBF series crossed roller bearings, equivalent to IKO products, allowing for cross-referencing and interchangeability. These bearings feature an integral inner and outer ring design with pre-machined mounting holes, eliminating the need for fixed flanges and support seats, thereby optimizing axial space. The CRBF series crossed roller bearings consist of an outer ring, inner ring, cylindrical rollers, and spacers (or retainers). The rollers are arranged between the inner and outer rings with spacers to prevent collision. CRBF crossed roller bearings offer stable rotational precision and torque characteristics, suitable for applications involving rotation of both inner and outer rings, widely used in robotic waist joints, welding positioners, communication radars, precision measuring instruments, and more.

The CRBH series crossed roller bearings manufactured by AUBEARING are one of the types within the crossed roller bearing lineup, characterized by an integrated inner and outer ring design and a thin-section structure. This type of bearing features integral inner and outer rings without mounting holes, allowing for use with supporting seats for fixation. The integrated structure of the inner and outer rings ensures that the bearing's performance is not affected by the installation process, maintaining stable torque and precise rotation. High-quality raceways and spacers aid in retaining rotational flexibility. With cylindrical rollers arranged in a cross formation, the bearing can withstand loads from multiple directions, offering 3-4 times higher rigidity compared to traditional designs. Additionally, the adjustable clearance of crossed roller bearings enables high-precision rotational motion even under preload.

The RU series crossed roller bearings consist of an integrated inner and outer ring design with mounting holes, eliminating the need for flanges and support seats during installation. The integrated structure of both rings ensures minimal impact on performance during installation, thereby maintaining stable rotational precision and torque. Suitable for applications requiring rotation of both the inner and outer rings, these bearings feature two rows of cylindrical rollers arranged in a 90-degree V-shaped groove with nylon separators, enabling them to withstand radial, axial, and moment loads from multiple directions. The compact dimensions of the inner and outer rings, coupled with an ultra-thin section approaching its limits, provide high rigidity, approximately 3-4 times that of traditional bearings. AUBEARING manufactures these crossed roller bearings with precision up to P2 grade and offers a minimum order quantity of 1 unit.Description

The SX series crossed cylindrical roller bearings, under similar shaft conditions compared to the RB series, feature a smaller cross-sectional size due to their ultra-thin design. The outer and inner rings do not have mounting holes, requiring flanges and support seats for installation, making them suitable for applications where the inner ring rotates. The dimensions of the inner and outer rings are minimized to the extreme, particularly in their ultra-thin structure approaching its limits, providing high rigidity. This makes them ideal for joints or rotating parts of industrial robots, rotating worktables in machining centers, robotic arm rotating parts, precision rotary tables, medical instruments, and similar applications.

AUBEARING manufactures XV series crossed roller bearings with dimensions ranging from 30mm to 110mm internal diameter and 75mm to 180mm external diameter. These bearings are suitable for both inner and outer ring rotation. The XV series crossed roller bearings consist of an integrated outer ring with mounting holes, a split inner ring, and a set of cylindrical rollers separated by spacers or retainers to prevent mutual contact.
