Cylindrical roller bearings without inner ring ribs (NU0000 type) and no outer wall (N0000) what is the difference in application? Without inner ring ribs (NU0000 type) is a separable inner no outer wall (N0000) is the outer ring can be separated, they both have what specific differences in the application?
10, without inner ring rib conical bore double row cylindrical roller bearing (type NNU..K), 11 conical bore double row cylindrical roller bearing (NNU..K/W33) 12, without inner ring rib of cylindrical roller bearings (NNU... K/W33) 13, inner ring, no side, tapered hole, double row cylindrical roller bearing (NNU..K/W33), free end bearing is non positioning end bearing"
With single rib of cylindrical roller bearing inner and outer rings are only small, can withstand constant axial load or axial load. With larger batch bearings can only bear a single rib The direction of the axial load. The specific classification and model control: 1, without inner ring rib of cylindrical roller bearing (type NU), 2 single ribbed cylindrical roller bearing inner ring (NJ type) 3, inner ring single flange with flat cylindrical roller bearing retainer (NUP type) 4, no outer wall (N type cylindrical roller bearing 5), the inner single flange with inclined ring of cylindrical roller bearing (type NJ+HJ), 6 outer single ribbed cylindrical roller bearing (type NF), 7 double row cylindrical roller bearing (type NN), 8 conical bore double row cylindrical roller bearing (NN... K type) 9, without inner ring rib of cylindrical roller bearings (NNU type)
No outer wall of cylindrical roller bearing N0000 (20000) and without inner ring rib of cylindrical roller bearing NU0000 (3200) - Characteristics of bearing inner and outer ring, cage and roller bearings can be separated, convenient installation and disassembly, only bear radial load. (KOYO samples: NU type and N type allows the axis relative to the shell axial to move in a certain range so the most suitable for use as a free end bearing!) cylindrical roller bearing type NU and type N, allows the axis relative to the bearing box for two-way axial displacement in a certain range, which can withstand axial length changes caused by thermal expansion, it is suitable to use as a non locating bearing can bear radial load. Great, but can not bear the axial load.
