ໄດ້ QJ206MA ແມ່ນປະເພດສະເພາະຂອງ ການຕິດຕໍ່ບານຕິດຕໍ່ເປັນລ່ຽມ. ນີ້ແມ່ນການແບ່ງແຍກຂອງຄຸນລັກສະນະແລະສະເພາະຂອງມັນ:
1. Type of Bearing:
- ການຕິດຕໍ່ບານຕິດຕໍ່ເປັນລ່ຽມ: Designed to handle combined radial and axial loads, these bearings have contact angles that enable them to support higher axial loads compared to deep groove ball bearings. They are typically used in pairs or sets to accommodate loads in both directions.
2. Bearing Designation:
- QJ206MA:
- QJ: Indicates a four-point contact ball bearing, which is a type of angular contact bearing. It can handle axial loads in both directions and radial loads simultaneously.
- 206: Specifies the size of the bearing. ໄດ້ “2” indicates a light series, ແລະ “06” refers to the bore diameter (30 ມມ).
- MA: Denotes the material or design specifics. “MA” typically means the bearing has a brass cage (retainer) and is designed for high-speed applications.
3. ຂະໜາດ:
- ເສັ້ນຜ່າກາງ Bore (ງ): 30 ມມ
- ເສັ້ນຜ່າກາງນອກ (ງ): 62 ມມ
- ກວ້າງ (ຂ): 16 ມມ
4. ການໃຫ້ຄະແນນໂຫຼດ:
- ການໃຫ້ຄະແນນການໂຫຼດແບບເຄື່ອນໄຫວ (ຄ): The maximum load the bearing can handle while rotating.
- ການໂຫຼດທີ່ສະຖິດ (C0): The maximum load the bearing can handle while stationary.
(Exact load ratings depend on the manufacturer and should be verified from the product datasheet.)
5. ຄໍາຮ້ອງສະຫມັກ:
- Angular contact ball bearings like the QJ206MA are commonly used in:
- spindles ເຄື່ອງມືເຄື່ອງຈັກ
- ປ້ຳ
- ກ່ອງເກຍ
- High-speed applications
- Applications requiring precise axial and radial load handling
6. ວັດສະດຸ cage:
- ໄດ້ “MA” suffix indicates a brass cage, which is durable and suitable for high-speed operations.
7. Lubrication and Sealing:
- ໂດຍປົກກະຕິ, these bearings are lubricated with grease or oil. Sealing options (e.g., rubber seals or metal shields) may vary depending on the application.
8. ການຕິດຕັ້ງ:
- Angular contact bearings are often mounted in pairs (back-to-back, face-to-face, or tandem) to handle axial loads in both directions.
If you need more specific details (e.g., ການໃຫ້ຄະແນນໂຫຼດ, tolerances, or exact dimensions), refer to the manufacturer’s datasheet or product catalog. Popular manufacturers of such bearings include SKF, NSK, FAG, ແລະ ຂວູ.
