What Are Crossed Roller Bearings?
Crossed roller bearings provide compact support for radial loads, axial loads in both directions and tilting moments in precision rotary assemblies.
Combined Load Support in One Bearing Position
In the common crossed cylindrical roller design, adjacent rollers are arranged with their axes alternately at 90 degrees between the inner and outer rings. This arrangement supports combined loads within a compact bearing envelope.
A crossed roller bearing can simplify some paired bearing arrangements, provided that load capacity, stiffness, accuracy and mounting requirements are verified. It is not automatically a direct replacement for an existing bearing set.
Rotary performance depends on the selected bearing configuration, preload or clearance, ring accuracy and the rigidity of the shaft and housing. Crossed tapered roller bearings use a different roller and raceway geometry and should be evaluated separately.
Compact Arrangement
Combines multiple load-support functions in one bearing position, helping simplify space-constrained rotary designs.
Radial, Axial & Moment Loads
Supports loads from multiple directions. Combined loading must be checked against the selected model's ratings and limits.
Rotary Stiffness & Accuracy
Suitable configurations can provide rigid, accurate rotary support when preload, mounting and surrounding structures are properly controlled.
Common applications include robot joints, precision rotary tables, indexing units, machine tool rotary axes and measuring equipment. Selection should follow the loads, motion and accuracy requirements of the specific bearing position.

Advantages of Crossed Roller Bearings
Crossed roller bearings help designers combine load support, compact dimensions and rotary stiffness. The benefits depend on selecting the right configuration and mounting it correctly.
Combined Load Support
One bearing can support radial loads, axial loads in both directions and overturning moments. This helps consolidate load support in one rotary position, with capacity checked for the actual combination of loads.
Space-Saving Rotary Design
A compact bearing envelope can reduce the space needed for separate radial and thrust supports. Some multi-bearing arrangements can be simplified when load capacity, stiffness and mounting requirements are satisfied.
High Rotary Stiffness
Roller-to-raceway line contact and a suitable preload can help limit displacement under load. Assembly stiffness also depends on ring support, housing rigidity and the clamping arrangement.
Precision Rotary Support
Appropriate bearing accuracy and controlled installation can help achieve low radial and axial runout. Positioning accuracy and repeatability also depend on the drive, feedback system and surrounding structure.
Crossed Roller Bearing Applications
From robot joints to precision rotary tables, crossed roller bearings support compact rotary mechanisms under combined loads. Each application requires its own load, motion and mounting checks.
Industrial Robots
Used in joint, wrist and arm rotation units where space is limited. Selection should account for overturning moments, reversing motion, joint stiffness and starting torque.
Rotary Tables
Supports indexing tables and rotary platforms under combined loads. Check workpiece weight, load offset, table stiffness, runout and the indexing duty cycle.

Inspection & Measuring Equipment
Provides rotary support for measuring instruments and inspection platforms. Important checks include radial and axial runout, torque variation, mounting accuracy and temperature stability.
Medical Equipment
Can support compact positioning and rotary mechanisms. Confirm motion torque, load deflection, lubrication, sealing and any equipment-specific cleanliness or validation requirements.
Automation Equipment
Used in rotary modules, handling systems and positioning devices. Check acceleration, reversing cycles, peak loads, mounting interfaces and maintenance access.
How to Select Crossed Roller Bearings
Check these six factors to select a suitable bearing or verify an existing model replacement.
Loads & Bearing Life
Check radial loads, axial loads and overturning moments, including peak loads and required service life.
Rotating Ring
Confirm whether the inner or outer ring rotates, then choose a suitable ring structure and support arrangement.
Dimensions & Mounting
Verify bore, outside diameter, width, mounting holes and fits, together with shaft and housing support.
Accuracy & Preload
Specify radial and axial runout, required stiffness, and preload or clearance for the rotary assembly.
Operating Conditions
Confirm speed, reversing or oscillating motion, temperature, lubrication and sealing requirements.
Replacement Verification
Compare the full original designation and drawing. Matching dimensions alone does not guarantee interchangeability.

Crossed Roller Bearing FAQs
Common questions about selection, replacement, custom options, quotation and delivery.
What is a crossed roller bearing?
A cylindrical crossed roller bearing has rollers arranged alternately at right angles. It supports radial loads, axial loads in both directions and overturning moments in one compact assembly. Capacity must be checked for the actual combined loads.
Are “cross roller” and “crossed roller” bearings the same?
The terms usually refer to the same bearing type. Confirm the full model designation, as ring structure, roller type and mounting details can differ.
How do I select the right crossed roller bearing?
Check loads, required life, rotating ring, mounting dimensions, accuracy, preload and operating conditions. See our selection guide or send TEDIN your drawing and application requirements.
Can TEDIN supply replacements for THK, IKO or other brands?
TEDIN can review replacement options using the original manufacturer's full designation and drawing. Dimensions, mounting, ring structure, accuracy, preload and load ratings must be compared. Matching dimensions alone does not guarantee interchangeability.
Do you offer custom crossed roller bearings?
Custom options can include dimensions, mounting holes, ring or gear structure, accuracy, preload, material, seals and lubrication. Send your drawing and requirements for a technical feasibility review.
What information is needed for a quotation?
Send the full bearing designation or drawing, order quantity and required delivery date. For a new design, include loads, speed, mounting, accuracy and preload or clearance requirements.
