This 6203RS bearing is a sealed ball bearing measuring 17x40x12. This single-row bearing is built to support radial loads and has a revolutions per minute (RPM) limit of 12,000 with greased lubrication. It is made from chrome steel for durability and resistance to deformity under heavy loads. This bearing has rubber seals on both sides to keep lubricant in and contaminants out and has been lubricated at the manufacturer so no additional lubrication is required.
Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. All rolling bearings are open, shielded, or sealed. Sealed bearings are lubricated with oil or grease in the bearing factory, while open and shielded bearings are meant to be lubricated in place, with periodic reapplication of lubrication, based on use. The shield protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.

I can't vouch for them in high-speed situations, but they work fine for low-speed. I also can't vouch for longevity.
For common everyday use there okay. I don't think I'd use these in medical equipment, because I don't know the properties.
But like I say, for my purposes, the price, including shipping, was dirt cheap. Works for me,
Interesting that one of the two 6203 sealed bearings that I just got (not this brand) from a local automotive parts store, had very little grease in it. the other sealed bearing had 2 times as much but could have used a lot more. So, this is why the original sealed bearing on the z225 John Deere failed, AND on the sears riding mower: From the factory they didn’t have enough grease sealed in them and were sealed to keep any more getting in. So I opened one side up on both of the new 6203 sealed bearings, ADDED more grease, and as in my application it will be greased using the grease zerk on the spindle shaft.
So, I recommend getting the best quality sealed bearings, perhaps like this brand.
