China export directly, trustworthy NN3012 Cylindrical roller bearing

1.cylindrical roller bearing with brass/bronze cage and removable inner ring suitable for high radial loads
2.C3 radial clearance is larger than normal allowing for thermal expansion
3.Single row roller bearing for high radial loads with low friction
4.Removable inner ring in open bearing allows for lubrication in place
5.Combination brass/bronze cage sustains high loads and reduces noise and friction
