Applications
6202 bearings are commonly used in a wide range of applications, including:
- Electric motors
- Gearboxes
- Pumps
- Conveyors
- Automotive components
- Appliances
Key Considerations
-
Load capacity: Ensure that the bearing can withstand the expected loads.
-
Speed: Consider the maximum operating speed of the bearing.
-
Lubrication: Proper lubrication is crucial for optimal performance and longevity.
-
Mounting: Proper mounting techniques are essential to avoid bearing failure.
-
Environmental conditions: Consider the effects of temperature, moisture, and other environmental factors.
Lubrication Strategies
-
Greasing: Apply grease to the bearing through a grease nipple or by hand.
-
Oil lubrication: Use a drip-feed or circulating oil system to provide lubrication.
-
Dry lubrication: Use solid lubricants like graphite or molybdenum disulfide when lubrication is not practical.
Humorous Stories and Lessons Learned
Story 1:
A technician mistakenly used a 6203 bearing instead of a 6202 bearing in a gearbox. The gearbox failed prematurely due to the incorrect bearing size. Lesson: Always double-check bearing dimensions before installation.
Story 2:
A factory was using 6202 bearings in their electric motors without proper lubrication. The bearings seized up, causing motor failures. Lesson: Proper lubrication is essential for bearing longevity.
Story 3:
A designer specified 6202 bearings for a conveyor system without considering the environmental conditions. The bearings failed due to corrosion from moisture exposure. Lesson: Environmental factors should be considered when selecting bearings.
Step-by-Step Mounting Approach
- Clean and inspect the bearing surfaces.
- Apply a thin layer of lubricant to the bearing components.
- Align the bearing correctly on the shaft or housing.
- Secure the bearing using a press or other appropriate method.
- Check the alignment and tighten all bolts or screws.
