Insert Ball Bearings
Mounted Bearings for Quick Installation and Misalignment Compensation
General Information
Our selection of insert ball bearings includes both original and compatible models from top manufacturers such as SKF, FAG, NSK, NTN, and INA. These units are designed for mounting in housing assemblies and are widely used in applications requiring simple installation, robust support, and resistance to misalignment.
Insert bearings feature a spherical outer surface that fits into matching housings, allowing for self-alignment and reducing the impact of shaft deflection or mounting errors. They are typically equipped with extended inner rings and locking mechanisms such as set screws or eccentric collars for easy shaft attachment. Available in sealed or shielded variants, they are factory-lubricated and ready for use.
Insert bearings are ideal for equipment with moderate loads, low to medium speeds, and frequent maintenance cycles. Common materials include chrome steel for inner and outer rings and nitrile or Viton seals for protection against contaminants. Options include different shaft locking systems, internal clearances, and lubrication types.
Common Applications
- Agricultural machinery and implements
- Material handling and conveyor systems
