635-2RS Rubber Sealed Bearing 5x19x6mm for Small Motors 

635-2RS miniature bearing - the "heart" of high-speed rotation

【Accurately match your device requirements 】
In the demanding field of high-speed micro-motors and precision instruments, reliability is paramount. The 635-2RS bearing, with its compact size of 5mm inner diameter, 19mm outer diameter, and 6mm width, is engineered to deliver exceptional performance under stress. We understand that your application requires more than just a rotating part; it demands minimal friction, high rotational stability, and resilience against contaminants. This 635-2RS bearing is meticulously crafted to meet these rigorous challenges.

 【Core Parameters 】

[Technical hard Power - Why Choose Us ]

Robust Sealing Performance: Designed for environments where dust and moisture are present, the 635-2RS features dual rubber contact seals. Unlike open or shielded bearings, these seals provide a physical barrier that effectively blocks foreign particles and retains grease, ensuring consistent lubrication and preventing premature failure in devices like electric toothbrushes or outdoor RC models.Optimized for High Rotational Speed: The 635 series is distinctively known for its ability to handle higher speeds compared to the 62 series of the same bore size. Through precision grinding and heat treatment (hardness HRC 60-65), the bearing minimizes heat generation and maintains dimensional stability, allowing for smooth operation at speeds exceeding 30,000 RPM in optimal conditions.Low Friction & Energy Efficiency: For battery-powered devices where every milliamp counts, our 635-2RS bearings are manufactured with strict tolerance controls on the raceway surface finish. This reduces rotational torque, lowering power consumption and extending the battery life of your portable equipment.Premium Material Integrity: We utilize vacuum-degassed GCr15 steel, which significantly reduces oxygen content and non-metallic inclusions. This results in a denser microstructure, offering superior fatigue resistance and a longer service life compared to standard carbon steel bearings.

【 Application Scenarios - Solving Your Industry Pain Points 】
 *   RC Hobby & Drones:  
 *   Issues: High vibration and shock loads during flight or racing can destroy inferior bearings.   
 *   Solution: The 635-2RS offers a robust cross-section (6mm width) that provides excellent load-carrying capacity. The rubber seals protect the internals from track dust or outdoor debris, ensuring the motor maintains peak RPM         throughout the race.
 *   Dental & Medical Equipment:  
 *   Issues:Need for sterile, smooth, and quiet operation without overheating.
 *   Solution: Our high-precision grades (ABEC-5/ABEC-7 available) ensure near-silent operation with negligible vibration. The sealed design allows for easy external disinfection without water ingress damaging the internal grease. 
*   Industrial Micro-Motors:
 *   Issues:Continuous 24/7 operation leads to heat buildup and grease leakage. 
 *   Solution:The 635-2RS is packed with high-quality lithium complex grease that withstands elevated temperatures. The seals lock this grease in, providing a "maintenance-free" lifecycle for conveyor sensors or small gearboxes.
