2. Installation
Correct installation is crucial for the optimal performance and longevity of the bearing.
- Forberedelse: Ensure the shaft and housing seats are clean, free from burrs, and within specified tolerances.
- Håndtering: Handle the bearing with clean hands or gloves to prevent contamination. Do not remove the bearing from its protective packaging until immediately before installation.
- Montering:
- 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.
- Smøring: 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.
- Forsegling: Ensure proper sealing is in place to protect the bearing from contaminants and retain lubricant.
3. Betjening
The MRC 207 SZZG is a single row deep-groove ball bearing designed to accommodate radial and axial loads in both directions.
- Belastningskapacitet: Operate the bearing within its specified radial and axial load limits to prevent premature failure.
- Hastighedsgrænser: Adhere to the maximum permissible operating speeds to avoid excessive heat generation and wear.
- Temperatur: Monitor the operating temperature. Excessive heat can degrade lubricant and bearing materials.
- Vibration og støj: Unusual vibration or noise during operation may indicate an issue requiring immediate attention.
4. Vedligeholdelse
Regular maintenance extends bearing life and ensures reliable performance.
- Smøring: Re-lubricate the bearing at recommended intervals using the specified compatible grease. Over-lubrication or under-lubrication can both be detrimental.
- Inspektion: Periodically inspect the bearing and its housing for signs of wear, corrosion, damage, or lubricant leakage. Check for unusual noise or vibration.
- Rensning: If the bearing is exposed to contaminants, ensure seals are intact and consider cleaning the surrounding area to prevent ingress.
- Udskiftning: Replace bearings that show signs of significant wear, damage, or excessive noise/vibration to prevent catastrophic failure of the machinery.
5. Fejlfinding
Refer to the table below for common issues and potential solutions.
| Symptom | Mulig årsag | Handling |
|---|---|---|
| Overdreven støj/vibration | Lack of lubrication, contamination, improper installation, bearing damage, misalignment. | Check lubrication, inspect for contaminants, verify installation, replace damaged bearing. |
| Overophedning | Insufficient lubrication, over-lubrication, excessive load, high speed, tight fit, inadequate cooling. | Adjust lubrication, reduce load/speed, check fit, improve cooling. |
| For tidlig fiasko | Contamination, improper installation, overloading, fatigue, corrosion. | Review installation procedures, ensure proper sealing, verify load calculations, inspect for environmental factors. |
