Which bearing is better ZZ or 2RS?
Re: Bearings types difference The 2RS are sealed for life bearings i.e. the grease within the bearing cannot get out or contaminants get into the bearing and damage it. The ZZ are just a metal shield to stop larger contaminants damaging the bearing.

What is a R12 2RS ball bearing made of?
This R12-2RS 3/4×1-5/8×7/16-inch sealed ball bearing has deep groove geometry for high speeds and supporting both radial and axial loads. The bearing is made of chrome steel for durability and resistance to deformity under heavy loads, and it has rubber seals on both sides of the bearing to keep lubricant in and contaminants out.

What are the different types of rolling bearings?
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.
What is the temperature range for the r12-2rs oil?
