ER Cartridge Ball Bearing Inserts
Insert bearings
with an extended inner ring are often referred to as “ER
style” or “ER Series” bearings. They are
specifically designed for mounting on shafts without using adapters, lock-nuts,
or shoulders. They are popular in many applications due to their versatility,
and cost effectiveness. The bearing is typically
locked in place using setscrews (or a locking eccentric collar). The inner ring
usually extends on both sides of the bearing to provide extra shaft
support.
AST’s ER Series insert bearings are typically used in applications in the following industries:
- Agricultural
- Conveyor / conveyance
- Construction
- Food and beverage processing
- Packaging
- Textile
