625-2RS Rubber Sealed Bearing 5x15x5mm for Low-Noise Motors 

6252RS miniature bearing - the "immune system" of the equipment

【Accurately match your device requirements 】
In the precise world of micro transmissions, although the size is small, it still undertakes crucial operational tasks. The 625RS bearing, with a standard size of 5mm inner diameter, 15mm outer diameter, and 5mm width, has become an indispensable core component in numerous small and precise equipment. Nova Precision Bearing understands that you are not merely looking for a "bearing"; what you need is ultimate sealing, ultra-low noise, and extremely long continuous working time. This 625RS bearing is precisely designed to address these pain points.

 【Core Parameters 】

[Technical hard Power - Why Choose Us ]
- Ultimate Sealing Technology: To address the requirements of humid and dusty environments as well as devices such as electric toothbrushes and high-speed spindles, we have adopted a double-sided rubber sealing ring (RS) design. Compared to the metal dust-proof cover (ZZ), the rubber seal can effectively prevent moisture, oil stains, and tiny particles from entering the bearing interior, while locking in the internal grease to ensure long-term stable operation in harsh conditions.
- Low Noise Silent Operation: For devices that are sensitive to noise (such as massage devices and precision instruments), we have carried out ultra-precision grinding treatment, controlling the operating noise to below 20 decibels. There is no longer any need to worry about the equipment emitting harsh squealing sounds, providing a quiet usage experience.- High Speed Stability: Ordinary bearings tend to heat up and deform at high rotational speeds. Our 625RS undergoes special heat treatment, with a hardness of HRC 62-65, combined with an optimized internal clearance, achieving a maximum rotational speed of 25,000 revolutions per minute, ensuring smooth operation at high speeds without stalling and stable power output.- Ultra Long Life Design: Using high-purity GCr15 bearing steel, which is vacuum-degased during smelting and has extremely low impurity content. Combined with the rubber sealing ring to lock in the oil, the lifespan is extended by at least 30% compared to open-type bearings.

【 Application Scenarios - Solving Your Industry Pain Points 】
 *   Micro drones / model aircraft:   
 *   Issues: Light weight of the body, high power loss, and complex flight environment (possibly with dust or light rain).   
 *   Solution: 6042RS is lightweight and has low friction torque, which can significantly increase the endurance and climbing speed of the drone; the rubber sealing ring effectively prevents dust from entering the motor, prolonging the lifespan of the aircraft.
 *   Smart home / electric tools:   
 *   Issues: Long-term continuous operation, with the environment possibly containing wood chips, dust, or cleaning water.  
 *   Solution: High sealing performance ensures that the bearings can still run smoothly in harsh conditions; strong wear resistance, capable of continuous operation for over 10,000 hours, significantly reducing equipment maintenance costs.
 *   Precision reduction motor: 
 *   Issues: Compact space, extremely high requirements for bearing size precision and cleanliness.
 *   Solution: High precision tolerance control to ensure zero vibration at high speeds; combined with high-temperature disinfection, it does not rust and is suitable for medical or food-grade equipment.

【 Commitment to quality】
"Steady as a rock, fearless of challenges"
Every 625RS bearing produced by us embodies our ultimate pursuit of "stable operation". We do not merely offer a single component; we provide comprehensive protection capabilities around the clock:
