RB3010 Crossed Roller Slewing Bearing THK Bearing Dimensions 30 X 55 X 10 Mm RB3010UUCC0
Cross Roller Bearings are high-precision, compact bearings designed for applications requiring high rigidity, low friction, and precise rotation. Their unique structure allows them to handle radial, axial, and moment loads simultaneously.
1. Core Structure of Cross Roller Bearings
The key design feature is the 90° cross arrangement of cylindrical rollers, which eliminates internal clearance and ensures even load distribution. Its main components include:
Outer Ring & Inner Ring: Typically made of chromium bearing steel for high hardness and wear resistance. One ring has a full raceway, while the other has a split structure (fixed with bolts) for easy assembly.
Cylindrical Rollers: Arranged alternately at 90° between the inner and outer rings. They directly contact the raceways, reducing deformation under load and improving rigidity.
Spacers/Retainers: Separate individual rollers to prevent friction and collision, ensuring smooth rotation and extending service life.
2. Key Performance Characteristics
High Rigidity: The cross roller arrangement and tight fit between rollers and raceways minimize elastic deformation, making them ideal for precision positioning.
Multi-Load Capacity: Can withstand radial loads, axial loads (both directions), and moment loads (tilting moments) in a single bearing, simplifying mechanical design.
Low Friction & High Precision: Direct roller-raceway contact reduces sliding friction, while strict manufacturing tolerances (often up to P5 or P4 class) ensure high rotational accuracy.
Compact Size: Integrates multi-load functionality into a single unit, reducing the overall volume of equipment compared to combinations of multiple bearings.
3. Typical Applications
Cross Roller Bearings are widely used in scenarios demanding precision and rigidity. Common application fields include:
Medical Devices: CT scanners, surgical robots, and precision diagnostic equipment.
Aerospace & Defense: Satellite antennas, radar turntables, and guidance system components.
Transportation: High-precision rotating parts in electric vehicles (e.g., steering systems) and railway inspection equipment.
