Effect of lubricant in Bearing
How can one put the property of lubricant in roller bearing and simulate it for vibration?
maybe this could help:
It is called "carrito de rulemanes" or "bring cart", translated to English.
If it is an open face b-ring (not sealed), you can just apply grease with your finger. (use latex gloves)
Or if it is a b - ring that it is sealed, it has the lubricant inside from factory.
I hope this could help you :)
