type bearing has no ribs, and the inner ring has ribs on both sides and a middle rib in the middle. It is possible to allow displacement between the shaft and the bearing seat in two directions in the axial direction.
The outer ring of the bearing has ribs on both sides and a middle rib in the middle, and the inner ring has no ribs. It allows axial displacement in two directions between the shaft and the bearing seat. Therefore, this type of structure is suitable for free end bearings. The cages of this type of bearings mostly use machined solid cages
Characteristics of cylindrical roller bearings
The rollers and raceways are in line contact or trimmed line contact. They have large radial load-bearing capacity and are suitable for bearing Heavy loads and shock loads.
The friction coefficient is small, suitable for high speed, and the limit speed is close to that of deep groove ball bearings.
The type and type can move axially and can adapt to changes in the relative position of the shaft and the housing caused by thermal expansion or installation errors. It can be used as a free end support.
The processing requirements for the shaft or seat hole are relatively high. After the bearing is installed, the relative deflection of the outer ring axis must be strictly controlled to avoid contact stress concentration.
The inner or outer ring can be separated for easy installation and disassembly
