Cylindrical roller bearing ETN9
Cylindrical roller and groove for line contact bearings. Load capacity, mainly bear radial load. Roller ring width and small, suitable for high speed raised edge friction spinning. According to the contractor, have raised edge can be points have NU, floatation, NUP, N, NF, etc, and single bearing NNU, such as NN by double row bearings. The bearing is inner ring and outer can separate structure. Inner circle or outer raised edge without the cylindrical roller bearing outer ring and, it can move relative to the axial, so can the bearings use as freedom. The outer circle, and one side have raised edge, another side of the rings with a single raised edge of cylindrical roller bearing, can take a certain degree of a direction axial load. General use stamping steel cage, or copper alloy car keep frame system. But there are also part of the use of polyamide forming cage.
Cylindrical roller bearing, the tectonic pattern:
1. No outer and inner circle raised edge N0000 type without raised edge NU0000 type cylindrical roller bearing these bearings can accept the big radial direction load, high speed limit, not bound shaft or shell of the axial displacement, cant accept the axial load.
2. The inner and outer raised edge all takes the cylindrical roller bearing NJ0000 type, NF0000 type bearings can be bound shaft or housing a direction of the axial displacement, and can accept smaller one-way axial load. NU0000 + HJ0000 type, NJ0000 + HJ0000 type, NUP0000 type bearings, can be in import bearing axial gap bound within the territory of the shaft or shell two directions of the axial displacement. And can accept smaller to bi-directional load.
Main applications: large and medium-sized motor, locomotives, spindle, internal combustion engine, generator, gas turbines, reducer, rolling mill, vibrating screen and lifting transportation machinery, etc.
