Single-row cylindrical roller bearing

  • Product features: The inner ring or outer ring can be separated for easy installation and disassembly; Large radial bearing capacity, suitable for bearing heavy load and impact load; Small friction coefficient, suitable for high speed, limiting speed close to deep groove ball bearing; N type and NU type can move axially and can be used as free end support; The processing requirements of the shaft or seat hole are higher to prevent the relative deviation, so as not to cause contact stress concentration.
  • Main areas: Large and medium-sized motors, rolling stock, machine tool spindles, internal combustion engines, generators, gas turbines, reducer boxes, rolling mills, shakers and lifting and transportation machinery, etc.

Single-row cylindrical roller bearing

Cylindrical roller bearing for cylindrical roller, roller type of bearings is separable, convenient for installation and removal, according to the ring with or without rim, can have N , NU, NJ, NF, NUP for single-row cylindrical roller bearing, and NNU, NN and other are for double-row cylindrical roller bearing, in addition to multiple-rows cylindrical roller bearing, because the cylindrical roller bearing generally uses alloy turning solid cage or engineering material cage, when the speed is low and the load is large, it can be designed into a full roller structure without cage.

Because the cylindrical roller bearing roller and raceway for line contact, load cutting capacity is large, mainly support radial load, the rolling body and the drawing finger edge contact is small, suitable for high-speed rotation, the use of high coaxiality requirements, the inner or outer cylindrical roller bearing without retaining edge, its inner ring and outer ring can be relative to the axial movement, so it can be used as a free end bearing, the inner ring and the outer ring on one side double rib, the other side of the ring has a single rib of the cylindrical roller bearing, can withstand a certain degree of single direction axial load.

HRB cylindrical roller bearing is known for its long life, professional design makes the bearing maximize the radial load cutting ability at the same time, different axial load capability, HRB for railway vehicles to provide chart column deep bearing using internal control thermal process method, so that the bearing surface has a stable compressive stress, as well as the overall excellent impact resistance.

N, NU type

The outer ring of the N-type bearing has no retaining edge, and the two sides of the inner band have retaining edge, which can allow the displacement between the shaft and the bearing seat in two directions in the axis, and the bearing of the NU air has retaining edge on both sides of the bearing ring, and the inner ring has no retaining edge, which can also allow the displacement between the shaft and the bearing seat in two directions in the axis. Therefore, this kind of structure is suitable for use as a floating end bearing.

NJ, NF type

NJ type bearing has a guard on both sides of the outer side, and a guard on one side of the inner figure, which can withstand a certain single coaxial load. The outer drawing of NF type has a guard side on one side, and the inner circumference has a guard side on both sides. It can also withstand a certain amount of unidirectional axial load. Therefore, this kind of structure is suitable for use as a single direction of axial positioning bearings.

NUP type

NUP type bearing is on both sides of the outer drawing with a guard, one side of the inner drawing with a (fixed) single guard, and the other is a separable flat gear chart, which can withstand a certain maximum two-way axial load.

NCF type

NCF type bearing is variants of single row cylindrical roller bearings, such as full complement cylindrical roller bearing are also available on customer’s request.
