6203-2RS Small Deep Groove Ball Bearings

6203-2RS Small deep groove ball bearings are standard sealed bearings designed for motors, mechanical equipment, agricultural machinery, and general transmission systems. The 6203-2RS adopts a double rubber sealed structure, providing strong protection against dust, water, moisture, and oil contamination.
With a standard size of 17mm inner diameter × 40mm outer diameter × 12mm width, this bearing uses GCr15 high carbon chromium bearing steel with heat treatment and precision grinding, offering high wear resistance, fatigue resistance, and stable operation.
The bearing features a high-strength stamped steel cage, pre-filled long-life grease, and standard P0 industrial precision grade. P6/P5 precision high-speed grades are available for customization. These Small deep groove ball bearings provide smooth rotation, low friction, and reliable performance for various transmission equipment.

Product Applications
6203-2RS bearings are widely used in industrial equipment, motors, transportation equipment, and mechanical transmission systems, including:
● Industrial and commercial motors
Single-phase motors, three-phase motors, gear motors, fan motors, water pump motors, and vibration motors.
● Agricultural and garden machinery
Harvesters, lawn mowers, hedge trimmers, and agricultural transmission equipment exposed to dust, mud, and moisture.
● Transportation equipment
Electric tricycles, electric vehicles, motorcycles, ATVs, and mobility equipment wheel shafts.
● Fans and pumps
Industrial fans, pipeline fans, booster pumps, circulating water pumps, and water treatment equipment.
● General mechanical equipment
Conveyors, production lines, packaging machines, printing machines, and small machine tools.
● Electric tools and cleaning equipment
Large grinders, polishing machines, industrial vacuum cleaners, and cleaning equipment.
● Transmission components
Industrial casters, heavy rollers, gear transmission systems, and automation equipment components.

Product Functions and Advantages
● 2RS double rubber seal for waterproof and dustproof protection
The 6203-2RS uses double-sided NBR rubber seals that tightly contact the inner and outer rings. The sealed design helps prevent dust, mud, water vapor, rainwater, oil, and small particles from entering the raceway, making it suitable for humid, dusty, outdoor, and light washing environments.
● Deep groove ball structure with stable load performance
The standard deep groove design supports strong radial loads and bidirectional axial loads. The bearing provides smooth rotation, low friction, stable starting performance, and reliable operation under different speed conditions.
● GCr15 bearing steel for long service life
High-quality GCr15 steel with hardening, tempering, and precision grinding processes provides high hardness, wear resistance, anti-pitting performance, and fatigue resistance for continuous operation.
● Full sealed maintenance-free design
Factory-filled long-life grease is locked inside the bearing by the rubber seal structure, reducing grease loss and maintenance frequency during normal working conditions.
● Standard size with easy replacement
The 6203-2RS is a common industrial bearing model with accurate dimensions and strong interchangeability, allowing direct replacement for many original equipment bearings.
● Stable supply for industrial purchasing
Standardized production provides sufficient inventory, stable delivery, and support for bulk orders and long-term factory supply.
