TEDIN has finished 10 pcs of single row cylindrical roller bearings NU3192M. They are ready for shipment today.
NU3192M is a single-row cylindrical roller bearing. The cylindrical rollers and raceways are linear contact. It mainly takes the radial load. The friction between the rolling element and the ring rib is small, which is suitable for high-speed rotation. According to the ring has ribs or not, it can be divided into single row cylindrical roller bearings such as NU, NJ, NUP, N, NF, and double row cylindrical roller bearings such as NNU and NN. The bearing has a separable structure with the inner ring and outer ring.
Cylindrical roller bearings with no ribs on the inner ring or outer ring, the inner ring, and the outer ring can move relative to the axial direction, so it can be used as a free end bearing or floating bearing. Cylindrical roller bearings with double ribs on one side of the inner ring and outer ring and a single rib on the other side of the ring can bear a certain degree of axial load in one direction. Generally, stamping steel cages or brass cages are used. However, there is also a part of the use of polyamide forming cage.
N, NU, NF, NJ, NUP Structures of Cylindrical Roller Bearings:
N-type structure: The inner ring has double ribs, which cannot be separated from the roller, and the outer ring has no ribs, which can be removed freely from both sides;
NU type structure: the outer ring has double ribs, which cannot be separated from the roller, and the inner ring has no ribs, which can be removed freely from both sides;
NF type structure: the inner ring has double ribs, which cannot be separated from the roller, and the outer ring has single ribs, which can only be removed freely from one side;
NJ type structure: The outer ring has double ribs, which cannot be separated from the roller, and the inner ring has a single rib, which can only be removed from one side;
NUP type structure: The outer ring has double ribs, which are inseparable from the roller. The inner ring has a single rib, which can be freely dropped from one side, but there is a positioning ring on the inner ring ribs, which can be removed.
