Fast shipping and well packed
Bearings arrived quickly and were well protected against moisture. Performance is solid, though I wish the packaging included more technical sheets.

Good precision, slightly pricey
We use these for small assembly machinery. The tolerance is excellent and they fit perfectly. Only giving 4 stars because bulk pricing could be better.

Exact fit for MR85
Ordered the 5mm bore size. Fits my RC car wheels perfectly without any wiggle room. Highly recommend for precision models.

Genuine Japanese quality
You can feel the difference in build quality. The wire-cut precision is evident. No noise or vibration during operation.

Perfect for my racing drone
These bearings are incredibly smooth. I noticed a significant improvement in motor spin-down time compared to my previous brand. High quality for the price.
Q: What is the exact tolerance for the 3mm bore size?
A: The bearings adhere to ABEC-7 standards, ensuring tight tolerance suitable for precision instruments. Please refer to the technical diagram for specific micron measurements.
Q: Can I use these in wet environments?
A: These feature metal shields (ZZ) which offer some protection, but they are not fully sealed against water. For wet environments, we recommend our 2RS rubber sealed series.
Q: Are these bearings suitable for high RPM applications?
A: Yes, the MR Series is designed for high-speed precision applications, typically supporting high RPMs common in drones and small machinery.
Q: Is the origin verified as Japan?
A: Yes, these are imported directly from Japan. Each package includes documentation verifying the country of origin.
Q: Do these come pre-lubricated?
A: Yes, all VNK MR Series bearings come pre-lubricated with high-speed grease suitable for most standard operating conditions.
