Excellent precision

We ordered a batch for our university lab. The runout is minimal, which is critical for our positioning accuracy tests. Highly recommend for educational and light industrial use.

Reliable replacement part

Used this to replace a worn-out bearing in a sorting robot. Installation was straightforward, and the machine is running smoothly again. Good durability so far after two weeks of continuous operation.

Compact and strong

The crossed roller design provides excellent rigidity in a very compact package. It handles both radial and axial loads efficiently in our multi-axis joint. No complaints at all.

Best value for money

Compared to imported brands, this domestic series offers incredible value. The performance is nearly identical for our application. Will definitely order again for our next build.

Perfect for my robotic arm project

The RA16013 bearing fits perfectly into my custom industrial arm design. The ultra-thin wall saved crucial space without compromising on load capacity. Very smooth rotation right out of the box.

Great quality, fast shipping

Solid construction and precise dimensions. I used these for a prototype assembly and they performed well under stress testing. Only minor issue was the packaging could be slightly more robust.

5 FAQ

Q: Can this be used in outdoor environments with dust exposure?

A: The standard model includes non-contact rubber seals which offer basic protection against dust. For harsh outdoor environments, we suggest adding additional protective covers or requesting a sealed variant if available.

Q: Is this bearing suitable for high-speed applications over 2000 RPM?

A: While designed for precision and load, we recommend consulting the speed rating chart for your specific lubrication setup. Generally, it performs well up to moderate high speeds, but cooling may be required for sustained operation above 2000 RPM.

Q: Does this come pre-lubricated or do I need to add grease?

A: Yes, the RA16013 series comes pre-greased with high-quality lithium soap grease, ready for immediate installation. Re-lubrication intervals depend on your operating conditions.

Q: What are the exact outer and inner diameter dimensions for the RA16013 model?

A: The RA16013 typically has an inner diameter of 160mm and an outer diameter of 190mm, with a width of 16mm. Please verify with the specific technical datasheet provided upon delivery.

Q: What is the warranty period for this industrial bearing?

A: We provide a standard 12-month warranty against manufacturing defects when used within the specified load and speed ratings. Proof of purchase and installation photos may be required for claims.
