- Product Description
Crossed Roller Bearing – Precision Engineering for High-Performance Applications
Product Details
When your application demands exceptional precision and compact design, our Crossed Roller Bearing delivers the performance you need. This advanced bearing solution features a unique cross-arrangement of cylindrical rollers positioned at 90-degree angles to each other. This distinctive configuration allows the bearing to handle axial loads, radial loads, and tilting moments simultaneously through a single bearing position. By eliminating the need for multiple bearing arrangements, you gain space savings and simplified assembly. Our product conforms to ISO dimension series 18 per DIN 616 standards, ensuring global compatibility and reliable performance across demanding industrial applications.
The bearing structure consists of precision-ground outer rings, inner rings, cylindrical rolling elements, and engineered plastic spacers. The outer ring features a split design secured by three retaining rings, facilitating straightforward installation and maintenance. V-shaped raceways machined into both rings provide optimal contact angles for the crossed rollers, distributing loads evenly across the bearing's contact surfaces.
We manufacture these bearings using high-strength alloy steel (50Mn or 42CrMo) for the rings and premium GCr15 bearing steel for the rolling elements. This material combination ensures durability under high loads while maintaining dimensional stability across temperature variations. Oil-resistant nitrile rubber (NBR) seals protect internal components from contamination in harsh operating environments.
Our production range covers bore diameters from 50 mm to over 2000 mm, with cross-section heights spanning 20 mm to 100 mm. This extensive size range accommodates applications from compact robotic joints to large-scale industrial turntables.

Features and Benefits
Space-Efficient Design
The crossed roller arrangement dispenses with the require for matched bearing courses of action. You can accomplish multi-directional stack bolster in a single compact unit, diminishing in general gathering weight and establishment space.
High Inflexibility and Running Accuracy
Cylindrical rollers give bigger contact ranges compared to ball orientation, coming about in prevalent solidness and negligible avoidance beneath stack. This inflexibility guarantees exact situating in applications requiring micron-level accuracy.
Multi-Directional Stack Handling
The X-arrangement of rollers empowers synchronous back of hub strengths from both bearings, spiral powers, and tilting minutes. This flexibility disentangles your bearing determination and decreases stock requirements.
Easy Establishment and Maintenance
The part external ring plan permits mounting without dismantling adjoining components. Holding rings secure the external ring segments whereas allowing clear substitution when upkeep is required.
Preload Choices for Zero Clearance
We offer heading with typical clearance, moo clearance, or preload arrangements. Preloaded orientation kill inside play, conveying greatest solidness for applications requesting zero backlash.
Applications
Industrial Robotics
Joint components, rotating tables, and arm congregations in collaborative robots and mechanical controllers advantage from the bearing's compact measure and exactness rotation.
Medical Imaging Equipment
CT scanners, MRI machines, and X-ray situating frameworks require smooth, vibration-free revolution. Our orientation work dependably in temperature-controlled clean room environments.
Machine Apparatus Spindles
Milling machines, machines, and pounding gear depend on inflexible bearing back to keep up cutting exactness and surface wrap up quality amid high-speed operations.
Aerospace and Defense
Antenna situating frameworks, flying machine landing adapt, and rocket direction instruments utilize these heading where weight lessening and unwavering quality are basic.
Semiconductor Manufacturing
Wafer handling robots and inspection platforms require contamination-free operation and repeatable positioning accuracy, both strengths of our Crossed Roller Bearing design.

FAQ
Q: What is the primary advantage of crossed roller plan over conventional ball bearings?
A: The round and hollow roller course of action gives altogether higher unbending nature and stack capacity in a more compact envelope. You get multi-directional stack back without requiring different bearings.
Q: Can these orientation handle stun loads?
A: Whereas outlined essentially for exactness applications with direct loads, our heading can endure restricted stun stacking. Counsel our designing group for particular application evaluation.
Q: What accuracy review ought to I indicate for mechanical applications?
A: Most automated joints perform well with P5 review. P4 review is suggested when your application requires situating exactness underneath 10 microns.
Q: Do you offer customized bore breadths exterior your standard range?
A: Yes. We give custom building administrations for non-standard measurements. Share your prerequisites, and our group will assess feasibility.
Q: How do I decide the fitting preload level?
