NU2238-E-M1 bearing is separable bearings, which are very convenient for installation and disassembly. Cylindrical roller bearings can withstand larger radial loads and are suitable for use in high-speed running situations.
The NU type bearing has ribs on both sides of the outer ring and no ribs on the inner ring. It can also allow displacement of the shaft relative to the bearing seat in both axial directions. Therefore, this type of structure is suitable for use as a floating end bearing.
NU2238-E-M1 Cylindrical Roller Bearing Features1. The roller and the raceway are in line contact or repaired offline contact, with a large radial bearing capacity, suitable for bearing heavy loads and impact loads.
2. The friction coefficient is small, suitable for high speed, and the limit speed is close to the deep groove ball bearing.
3. The N-type bearing and NU type bearing can move axially, can adapt to the change of the relative position between the shaft and the housing caused by thermal expansion or installation error, and can be used as free-end support.
4. The processing requirements for the shaft or seat hole are high, and the relative deflection of the outer ring axis after the bearing is installed must be strictly controlled to avoid contact stress concentration.
5. The inner ring or outer ring can be separated for easy installation and disassembly
NU2238-E-M1 Roller Bearing ApplicationLarge and medium-sized motors, locomotives, machine tool spindles, internal combustion engines, generators, gas turbines, gearboxes, rolling mills, vibrating screens, lifting and transporting machinery, etc.
