BB1-0978 Deep Groove Ball Bearing 30x72/79.5x21mm BB1-0978 Automobile Gearbox Bearing

BB1-0978 Deep Groove Ball Bearing 30x72/79.5x21mm BB1-0978 Automobile Gearbox Bearing

The BB1-0978 is a universal deep groove ball bearing engineered to handle radial loads primarily (and slight axial loads secondarily), with smooth rotation and wide adaptability—widely used in industrial motors, household appliances, mechanical transmission systems, and light-duty rotating equipment. Model breakdown: "BB1" denotes the general-purpose deep groove ball bearing series (optimized for universal load scenarios and easy installation); "0978" is the size & compatibility code (matches standard shaft/housing dimensions for targeted rotating assemblies, ensuring broad interchangeability). Its simple structure and reliable performance make it ideal for low-to-medium speed, general-load working environments (e.g., fan shafts, small gearboxes).
 
1. Specification:
 

• Main Applications:
  • Industrial motors (small AC/DC motor shafts, supports radial loads during stable rotation).
  • Household appliances (washing machine transmission shafts, fan impeller shafts, adapts to low-noise requirements).
  • Mechanical transmission systems (light-duty gearbox auxiliary shafts, handles torque transfer with smooth rotation).
  • Light industrial equipment (packaging machine conveyor rollers, textile machine guide wheels, balances durability and operational efficiency).
