Versatile:
They are known for their versatility, robustness, ease of maintenance, and cost- effectiveness.
Extended surface:
In bearings with a protruding inner ring, the inner ring has an extended surface beyond the normal width of the bearing.
Mounting and positioning:
This protrusion can be used to precisely locate the bearing within a housing or on a shaft, or to provide a surface for attachment or fixing.
Example:
Some bearings with a protruding inner ring might have a shoulder or a flange on the inner ring.
Applications:
Specific mounting requirements: Bearings with a protruding inner ring are used when a specific mounting arrangement or positioning of the bearing is needed. Compact designs: They can be helpful in compact designs where space is limited.
Examples: This feature can be found in various applications, including machinery, automotive components, and other industrial equipment.
Key features and considerations:
Open or sealed:
Deep groove ball bearings with a protruding inner ring are available in open versions (no seals or shields) or with seals and shields to protect the bearing from contaminants.
Cage material:
Cages are typically made of pressed steel, but high-speed bearings may use machined brass cages according to BBCR.
Filling slots:
Some deep groove ball bearings have filling slots to accommodate more balls for increased radial load capacity, but these may impact axial load capacity and speed.
