When designing automated equipment with limited space, maintaining precision can be a challenge. Complex or high-speed rotating loads often require larger bearings to ensure accuracy and rigidity. However, for space-constrained applications, crossed roller bearings provide an ideal solution by combining compact dimensions with exceptional performance.
Our CRBT105A crossed roller bearings are designed to deliver precise, repeatable motion while fitting seamlessly into tight spaces, making them an excellent choice for advanced automated and robotic equipment.
Small Size Meets High Performance
Crossed roller bearings feature rollers arranged alternately at right angles between the inner and outer rings. This unique design creates a larger contact surface, enabling the bearing to handle heavy and complex loads from multiple directions simultaneously. By utilizing this advanced design, crossed roller bearings allow for significant size reductions in automated equipment.
The CRBT105A model exemplifies this innovation with ultra-small dimensions:
Bore diameter: 10 mm.
Outer diameter: 21 mm.
Width: 5 mm.
With a sectional area half that of rear-mounted, 45-degree contact angle single-row roller or ball bearings, the CRBT105A provides superior space efficiency. Despite its compact size, it delivers rigidity up to four times greater than double-row angular contact ball bearings.
Key Features of the CRBT105A
Smooth Rotation: Cylindrical rollers with separators ensure smooth and stable movement.
Load Capacity: Dynamic load rating of 1,120N and static load rating of 811N.
Low Friction: Small coefficient of friction supports high-speed rotation.
Lightweight Construction: Optimized for space and weight-sensitive designs.
These features make the CRBT105A ideal for applications such as articulating robot arms and compact surveillance cameras, where handling complex, multi-directional loads is crucial.
Stay Ahead of Size Constraints
As automated equipment becomes increasingly compact, designers require solutions that balance precision, rigidity, and size. The CRBT105A crossed roller bearing meets these demands by offering exceptional rigidity and smooth performance in an ultra-compact package.
