NF cylindrical roller bearings

Structural features: The inner ring of NF series cylindrical roller bearings has double retaining edges that are inseparable from the rollers, while the outer ring has a single retaining edge. This design allows the bearing to only detach freely from one side, making it suitable for situations that require unidirectional axial positioning

1. Structural features: The inner ring of NF series cylindrical roller bearings has double retaining edges that are inseparable from the rollers, while the outer ring has a single retaining edge. This design allows the bearing to only detach freely from one side, making it suitable for situations that require unidirectional axial positioning
2. Load bearing capacity: NF series cylindrical roller bearings mainly bear radial loads and can withstand axial loads up to 10% of radial loads. Axial load transmits pressure between diagonally opposite retaining edges through sliding, suitable for unidirectional axial positioning bearings
3. Application scenarios: Due to the ability of NF series bearings to withstand certain axial loads and their compact structure, they are commonly used in mechanical equipment that requires unidirectional axial positioning, such as certain transmission devices and rotating equipment
4. Materials and Manufacturing Process: NF series cylindrical roller bearings generally use steel plate stamped retainers or copper alloy machined solid retainers, and in some cases use polyamide formed retainers. This design helps improve the durability and stability of bearings
