Die NJ222ECP is 'n tipe silindriese rollaer, commonly used in various industrial applications. Hier is 'n uiteensetting van die belangrikste kenmerke en spesifikasies:
1. Laer tipe:
- NJ: Dit dui die laertipe aan.
- NJ stands for a cylindrical roller bearing with a single flange on the outer ring and a double flange on the inner ring. This design allows for axial displacement in one direction and can handle radial loads.
2. Dimensies:
- 222: This refers to the bearing’s size designation.
- Bore Diameter (d): 110 Mm
- Buitenste deursnee (D): 200 Mm
- Breedte (B): 38 Mm
3. ECP Designation:
- EC: Stands for “Enhanced Capacity.” This means the bearing has an optimized internal design (bv., modified roller and raceway profiles) to increase radial load capacity and reduce stress.
- P: Indicates the use of glass fiber reinforced polyamide (PA66) as the material for the cage (also known as the retainer). This material is lightweight, durable, and suitable for high-speed applications.
4. Laai kapasiteit:
- Cylindrical roller bearings like the NJ222ECP are designed to handle high radial loads. Die “EC” design further enhances this capability.
- Axial load capacity is limited due to the single flange design, but it can handle some axial loads in one direction.
5. Toepassings:
- Commonly used in heavy machinery, gearboxes, electric motors, pumps, and other industrial equipment where high radial load capacity and moderate axial load handling are required.
6. Smering:
- Behoorlike smering is noodsaaklik vir optimale werkverrigting. Grease or oil lubrication can be used depending on the operating conditions.
7. Operating Conditions:
- Suitable for high-speed applications due to the polyamide cage.
- Can operate in a wide range of temperatures, but the cage material (PA66) has a temperature limit of around 120°C (248°F).
