Smooth operation
Very smooth rolling action right out of the box. The packaging protected the bearing well during transit. Highly recommend for hobbyist robotics projects.

Exact dimensions
Dimensions were exact to the datasheet, which made CAD integration and final assembly seamless. No modifications needed.

Solid performance
Using these for a light industrial application. They perform as expected under moderate load. Would have given 5 stars if they came pre-lubricated with high-temp grease.

Reliable components
We use these in several of our prototype units. They handle the crossed loads very well without deformation. Great value for direct manufacturer pricing.

Good quality, fast shipping
Ordered the RB45025 model for a rotary table setup. Quality seems solid and matches the specifications. Shipping was faster than expected from the manufacturer.

Perfect for my robotic arm project
These bearings fit perfectly into the joint assembly of my custom automation robot. The smoothness of rotation is impressive, and there was no noticeable play upon installation.
Q: Can I purchase just the RB45025 model separately?
A: Absolutely. You can select individual models from the dropdown menu on the product page or contact us directly for bulk orders of a specific size.
Q: What is the maximum rotational speed for the RB35020 model?
A: The RB35020 is designed for precision positioning rather than high-speed rotation. We recommend operating speeds below 60 RPM for optimal longevity and precision in robotic joints.
Q: What is the warranty period for these bearings?
A: All our crossed roller bearings come with a 12-month warranty against manufacturing defects when used within the specified load and speed ratings.
Q: Are replacement seals available for these open bearings?
A: Currently, these units are sold as open types. However, we offer custom sealing solutions for large volume orders. Please reach out to our sales team for customization options.
Q: Do these bearings come pre-lubricated?
A: Yes, they come with a standard anti-rust coating and light machine oil. For specific high-speed or high-temperature applications, we recommend applying your preferred specialized grease before installation.
