Factory Free sample Bicycle Ball Bearings - N307-E single row Cylindrical roller bearing – CWL Detail:

Single-row cylindrical roller bearings with a cage comprising cylindrical rollers caged between a solid outer and inner ring. These bearings have a high level of rigidity, can support heavy radial loads and are suitable for high speeds. The inner and outer rings can be fitted separately, making installation and removal a simple process.

The outer ring of an N series cylindrical bearing has no ribs, whereas the inner ring of the cylindrical bearing has two fixed ribs. This means that the N series cylindrical bearing cannot locate the shaft, therefore the axial displacement of the shaft relative to the casing can be accommodated in both directions.

Pressed steel or machined brass cages are generally used, but sometimes molded polyamide cages are also used.

The N307-E single row Cylindrical roller bearing , “E” suffix designates higher radial load capacity .
