Flanged bearings are a crucial component in various mechanical systems, providing support and reducing friction for rotating shafts. Their unique design, characterized by a flange that extends perpendicular to the bearing surface, offers several advantages and makes them suitable for a wide range of applications.
1. Flange Design
The flange of a flanged bearing is an annular extension that projects from the outer ring. It provides a rigid mounting surface for the bearing, allowing it to be securely fastened to adjacent components using bolts or clamps.
2. Bearing Type
Flanged bearings can incorporate different types of bearings, including ball bearings, roller bearings, and plain bearings. The choice depends on the specific application requirements, such as load capacity, speed, and precision.
3. Bearing Housing
The bearing housing is typically made of either metal or plastic and encloses the bearing. It provides support for the shaft and protects the bearing from contaminants.
Flanged bearings are commonly used in various industries, including:
Feature | Flanged Bearing | Standard Bearing |
---|---|---|
Mounting | Flange for easy attachment | Press-fit or snap-ring |
Housing | Integrated housing | Separate housing required |
Space Efficiency | Compact design | Bulkier |
Self-Alignment | Some designs have self-alignment capabilities | Typically require manual alignment |
Cost | More expensive | Less expensive |
Weight | Heavier due to flange | Lighter |
Flanged bearings play a critical role in many industries, offering:
Story 1:
A maintenance technician was servicing a conveyor belt and accidentally installed a flanged bearing upside down. As the belt started running, the bearing seized and sent metal shards flying, resulting in a comical display of sparks and laughter.
Lesson Learned: Always pay attention to the correct orientation of bearings during installation.
Story 2:
In a manufacturing plant, a team of engineers was struggling to align a series of flanged bearings. After hours of frustration, they realized that the bearings were slightly misaligned because they had mixed up left- and right-handed flanges.
Lesson Learned: Double-check the part numbers and ensure you have the correct flanges for the application.
Story 3:
During a product launch event, a robotic arm malfunctioned and dropped a heavy component onto a flanged bearing. The bearing miraculously survived the impact, but the engineers were left scratching their heads as to why it couldn't handle such a light load. Further inspection revealed that the bearing had been installed without lubrication.
Lesson Learned: Lubrication is essential for the proper functioning of bearings.

30 | 3.0 | 1.5 |
40 | 4.5 | 2.2 |
50 | 6.0 | 3.0 |
60 | 7.5 | 3.7 |
Table 2: Temperature Ratings of Flanged Bearings
Bearing Type | Temperature Rating (°C) |
---|---|
Ball Bearing | -20 to +120 |
Roller Bearing | -30 to +150 |
Plain Bearing | -40 to +200 |
