Analysis of full complement cylindrical roller bearings without outer ring
Full complement cylindrical roller bearings without outer rings, as a high-performance bearing type, have a unique structure and powerful functions. It mainly consists of an inner ring, multiple cylindrical rollers and a plastic protective sleeve. The inner ring has two fixed ribs to guide the rollers and bear the load, while the rollers roll through the ribs of the inner ring to withstand radial and axial forces. In addition, in order to protect the rolling elements from damage during transportation, they are usually wrapped in plastic sleeves.
The stud/shaft of combined roller bearings
The stud/shaft of combined roller bearings' materials are 20# steel.
Currently we have two types, one is natural color and the other is sandblasted.
