Great for wet environments

Using these in a pump application. Rust resistance is holding up well after a month.

Good quality, slow ship

Bearings look solid and stainless. Took a bit longer to arrive than expected but worth it.

Good value for money

Not high precision ABEC-7, but for general use these are excellent and priced well.
