Single Row Deep Groove Ball Bearings: Where They Actually Dominate
Core Role: Hold rotating shafts in place while handling combined radial weight (rotor gravity) + minor axial shifts (magnetic forces).
Real-World Examples:
Household: Vacuum cleaner fans, fridge compressors.
Industrial: Conveyor drive motors, HVAC blowers.
Why Deep Groove?: Compact, cheap, and sealed variants resist dust ingestion.
Core Role: Support radial loads (vehicle/freight weight) while tolerating side forces during turns.
Real-World Examples:
E-Scooters/Mobility Aids: Hub bearings in compact wheels.
Factory Carts: Castor wheels under heavy racks.
Why Deep Groove?: Handles wobble from uneven floors better than angular contact bearings.
Core Role: Absorb gear mesh vibrations + support shafts carrying radial-heavy loads.
Real-World Examples:
Power Tools: Drill gear trains transferring torque.
Agricultural Gearboxes: Tractor PTO shafts.
Why Deep Groove?: Survives gritty environments with rubber seals.
Core Role: Enable smooth rotation in gadgets where space/cost trump extreme precision.
Real-World Examples:
Washing Machines: Drum support bearings resisting soggy laundry imbalance.
Office Gear: Printer paper feed rollers, treadmill running decks.
Why Deep Groove?: Sealed units last 5+ years without maintenance.
Core Role: Handle moderate axial thrust (impeller pressure) + radial loads from piping.
Real-World Examples:
Water Pumps: Household pressure boosters.
Fuel Dispensers: Gas pump rotating assemblies.
Why Deep Groove?: Cost-effective for non-explosive fluids (avoid for acids/abrasives).
