XRSI series cross roller slewing bearings are precision bearings whose core feature lies in the internal structure. It has cylindrical rollers arranged in a 90°crossing arrangement, which enables a single bearing to withstand multiple loads such as radial, axial and tilting moments at the same time.
High Precision and Rigidity:
XRSI series crossed roller slewing bearings utilize the line contact between rollers and raceways to effectively reduce elastic deformation, allowing them to maintain excellent rigidity when subjected to high loads. The high-precision manufacturing process ensures low runout during operation, making them ideal for equipment with stringent precision requirements.
Compact Design and Light Weight:
Due to its internal roller cross-arrangement, one XRSI bearing can replace a pair of conventional angular contact ball bearings, greatly simplifying the mechanism design. This compact design not only saves mounting space, but also effectively reduces the overall weight of the equipment.
Excellent Load Carrying Capacity:
cross roller bearings can simultaneously withstand radial, axial and tilting moments, this multi-directional load carrying capacity makes it an ideal solution for heavy and complex load conditions.
Easy to Install:
XRSI series slewing bearings are usually of one-piece construction, which makes the installation process relatively simple and reduces assembly time and potential errors.
With its excellent performance, XRSI series crossed roller slewing bearings are widely used in the following high-tech fields:
Industrial robot joints: Robots need high-precision, high-rigidity joints for precise motion control. The compact design and high precision of XRSI series bearings make them the core components of robot joints.
Medical equipment: In CT machines, operating tables and other medical equipment, bearings are required to have high operational precision and reliability to ensure the accuracy of diagnosis and surgery.
CNC machine tool rotary table: automation equipment, such as CNC machine tool rotary table and indexing head, need high-precision slewing bearings to ensure the machining accuracy, the rigidity and accuracy of XRSI bearings to meet this demand.
Radar and Antenna: In radar and antenna systems that require precise rotation, XRSI series bearings are able to withstand wind loads and their own weight and ensure precise positioning.
