Type and features
| Type | Product Specifications | Ease of handling | Features |
|---|---|---|---|
| NKX | Radial bearing: Needle roller type steel retainer Thrust bearing: Ball type resin retainer Dust-proof cover: N/A Thrust plate: Separated type | △ Thrust plate separated type No dust-proof cover | The ball type thrust bearing makes it compatible with applications with light axial loads and high-speed rotation. |
| NKX··Z | Radial bearing: Needle roller type steel retainer Thrust bearing: Ball type Resin retainer Dust-proof cover: Available Thrust plate: Non-separated, integrated type | ○ Thrust plate integrated type Dust-proof cover equipped | It is a dust-proof cover equipped type of the NKX thrust bearing. The dust-proof cover also keeps the thrust plate integrated, making it easy to handle. |
About allowable rotational speed
This permissible rotational speed is the permissible rotational speed that can be achieved based on the following assumptions.
- Use under conditions where an appropriate amount of recommended grease is filled, a sufficient break-in operation is performed, and heat generated is eliminated by such as cooling the outer housing
- Use under constant preload
