The NJ212ECP waa nooc ka mid ah rullaluistemadka cylindrical, sida caadiga ah loo isticmaalo codsiyada warshadaha kala duwan. Halkan waxaa ah kala-goynta sifooyinkeeda iyo tilmaamaheeda muhiimka ah:
1. Nooca Dhalmada:
- NJ: Tani waxay tusinaysaa nooca xajinta. “NJ” Waxaa loola jeedaa rullaluistemadka cylindrical leh oo leh hal baal oo ku yaal giraanta dibadda iyo gees labanlaab ah oo giraanta gudaha ah. Naqshadeyntani waxay u oggolaaneysaa barakaca axial ee hal jiho.
2. Size and Dimensions:
- The “212” in the bearing code refers to its size. The dimensions for NJ212ECP are typically:
- Dhexroor gudaha ah (d): 60 mm
- Dhumo-saarid (D): 110 mm
- Ballaca (B): 22 mm
(Always verify dimensions with the manufacturer’s datasheet, as slight variations may exist.)
3. Magacaabidda ECP:
- EC: Waxay u taagan tahay “Naqshadaynta Gudaha La Habeeyay,” which means the bearing has a higher load capacity due to improved roller and raceway profiles.
- P: Indicates the use of glass fiber reinforced polyamide (PA66) as the cage material. This cage material is lightweight, durable, and suitable for high-speed applications.
4. Awoodda Xamuulka:
- Cylindrical roller bearings like the NJ212ECP are designed to handle high radial loads and moderate axial loads (in one direction).
- The exact dynamic and static load ratings depend on the manufacturer’s specifications.
5. Codsiyada:
- Cylindrical roller bearings are commonly used in:
- Matoorrada korontada
- Gearboxes
- Machine tools
- Automotive applications
- Mashiinada warshadaha
6. Lubrication and Maintenance:
- Saliid habboon ayaa lagama maarmaan u ah waxqabadka ugu fiican. Dufanka ama saliidda saliidda ayaa la isticmaali karaa iyadoo ku xiran codsiga.
- The bearing should be protected from contamination and operated within its temperature limits.
7. Manufacturer Variations:
- The NJ212ECP bearing is produced by various manufacturers (E.g., Ay gubta, FAG, Nsk, iwm.). While the basic dimensions are standardized, there may be slight differences in internal design, dulqaadasho, or materials. Always refer to the specific manufacturer’s datasheet for detailed information.
Haddii aad u baahan tahay faahfaahin dheeraad ah, sida ratings load, dulqaadasho, ama hagitaan codsi gaar ah, ii sheeg!
