2. Орнотуу
Correct installation is crucial for the optimal performance and longevity of the bearing.
- Даярдоо: Ensure the shaft and housing seats are clean, free from burrs, and within specified tolerances.
- Колдонуу: Handle the bearing with clean hands or gloves to prevent contamination. Do not remove the bearing from its protective packaging until immediately before installation.
- Монтаждоо:
- Cold Mounting: For small to medium-sized bearings, press the bearing onto the shaft or into the housing using a suitable mounting tool that applies force evenly to the inner or outer ring, respectively. Never strike the outer ring when mounting on a shaft, or the inner ring when mounting into a housing.
- Hot Mounting: For larger bearings or tight fits, heat the bearing in an oil bath or induction heater to a maximum of 120°C (248°F). This expands the bearing, allowing it to slide onto the shaft or into the housing easily.
- Майлоо: Apply a compatible grease, such as the recommended grease for ball bearings, to the bearing before or during installation, as specified by the application requirements.
- Мөөрлөө: Ensure proper sealing is in place to protect the bearing from contaminants and retain lubricant.
3. Операция
The MRC 207 SZZG is a single row deep-groove ball bearing designed to accommodate radial and axial loads in both directions.
- Жүктөө жөндөмдүүлүгү: Operate the bearing within its specified radial and axial load limits to prevent premature failure.
- Ылдамдык чектери: Adhere to the maximum permissible operating speeds to avoid excessive heat generation and wear.
- Температура: Monitor the operating temperature. Excessive heat can degrade lubricant and bearing materials.
- Вибрация жана ызы-чуу: Unusual vibration or noise during operation may indicate an issue requiring immediate attention.
4. Техникалык тейлөө
Regular maintenance extends bearing life and ensures reliable performance.
- Майлоо: Re-lubricate the bearing at recommended intervals using the specified compatible grease. Over-lubrication or under-lubrication can both be detrimental.
- Текшерүү: Periodically inspect the bearing and its housing for signs of wear, corrosion, damage, or lubricant leakage. Check for unusual noise or vibration.
- Тазалоо: If the bearing is exposed to contaminants, ensure seals are intact and consider cleaning the surrounding area to prevent ingress.
- Алмаштыруу: Replace bearings that show signs of significant wear, damage, or excessive noise/vibration to prevent catastrophic failure of the machinery.
