Why Choose XRSI Series for Precision Applications

The XRSI series cross roller slewing bearings are designed with a 90° crossing arrangement of cylindrical rollers, enabling them to withstand radial, axial, and tilting moments all at once. This design not only provides high rigidity and rotational accuracy but also ensures low runout during operation, critical for machinery with stringent precision requirements.

These bearings are compact and lightweight, simplifying mechanism design and reducing the overall weight of equipment. Their multi-directional load capacity makes them suitable for heavy and complex load conditions, such as those found in industrial robots, medical equipment, and radar systems.

The XRSI series is also known for its ease of installation due to its one-piece construction, which minimizes assembly time and potential errors. This, combined with its high precision and rigidity, positions the XRSI series as a leading choice in high-tech fields.

High precision manufacturing process ensures low runout.
Compact design replaces a pair of conventional bearings, saving space.
Multi-directional load capacity for heavy and complex loads.

Key Technical Features of XRSI Series

STEP 1

High Rigidity and Precision

XRSI series bearings utilize line contact between rollers and raceways to reduce elastic deformation, maintaining excellent rigidity under high loads and ensuring low operational runout.

STEP 2

Compact and Lightweight Design

The internal roller cross-arrangement allows one XRSI bearing to replace two conventional bearings, simplifying design and reducing equipment weight, which is beneficial for space and weight-sensitive applications.

STEP 3

Multi-directional Load Capacity

Capable of withstanding radial, axial, and tilting moments simultaneously, XRSI series bearings are ideal for applications with heavy and complex load conditions, such as in industrial machinery and robotics.

STEP 4

Ease of Installation

One-piece construction of XRSI series slewing bearings simplifies the installation process, reducing assembly time and the likelihood of errors, which is crucial for efficient manufacturing and maintenance.
