Stainless steel bearing W6304-2RS1 is designed with the prefix W, also know as SKF deep groove ball bearings, which manufacture in France plant, single row, seal on both sides. The bearing rings are produced from stainless steels X65Cr13, the balls are made of stainless steel X105CrMo17 and cages of stainless steel X5CrNi18-10. And these bearings are lubricated for life and are maintenance-free.

Following is the characteristics of SKF bearings W6304-2RS1, for your reference,

Explorer 7314BECBM is an ordinary SKF angular contact ball bearing, 73BE series, single row, with pressed window-type brass cage, ball centred, which can accommodate axial loads acting in one direction only. And these 73BE series provide longer service life, higher reliability and better performance, so they can be matched universally, such as arranged back to back or face to face as a pair.
