Low noise 6305-2RS deep groove ball bearing with double rubber 2RS seals. Ultra-quiet running is realized via multiple optimized technologies. Adopt vacuum degassed high-purity GCr15 steel and G5 precision steel balls. Super-finished raceways cut friction vibration greatly. Low friction PA66 cage avoids ball collision noise. NBR double lip 2RS seals block dust to prevent abnormal sound. Special silent grease provides stable lubricating film for smooth rotation. All units pass full vibration test and Z3 silent grade sorting. Perfect for silent motors, blowers, office equipment and small machinery.
How does our 6305-2RS realize low noise operation?
- Low noise performance achieved by G5 precision steel balls & super-finished raceway
- Vacuum degassed GCr15 steel reduces internal impurity noise
- Optimized PA66 silent cage eliminates ball collision noise
- NBR 2RS double lip seal prevents dust-induced abnormal sound
- Special low-noise grease forms uniform lubricating film to cut friction noise
- All bearings tested by vibration equipment, Z3 silent grade sorting
Applications
6305-2RS is widely used in medium-power and heavy-load household appliances, light industrial equipment and ventilation machinery, serving core rotating shaft positions that require high stability and load resistance.
Household & Commercial Electrical Appliances
It is a core universal bearing for large drum washing machines and high-load fully automatic washing machines, used for main drum spindle and bearing assembly to withstand dehydration high-speed rotation and eccentric clothing load. It is also applicable to high-power industrial fans, large ventilation blowers and commercial high-speed drying equipment.
Light Industrial & Processing Equipment
Suitable for medium-power power tools, industrial mixing and stirring equipment, small processing machinery transmission shafts and continuous operation workshop auxiliary equipment. Its high rigidity and impact resistance ensure stable operation under long-term medium-load working conditions.
General Mechanical Transmission
Widely used for conventional motor spindles, small generator equipment and general transmission mechanisms, providing reliable load support and high-speed stability for medium-power rotating machinery.

FAQ
Q1: What makes 6305-2RS different from ordinary 6200 series home appliance bearings?
A1: As a 6300 thick-wall series bearing, 6305-2RS features thicker steel wall, higher structural rigidity and stronger anti-deformation ability. It is not limited to light-load household scenarios like 6200 series. It supports medium-heavy eccentric load and long-term high-vibration operation, making it specially designed for high-load household appliances and light industrial equipment rather than ordinary small household devices.
Q2: What speed and load range is 6305-2RS suitable for?
A2: This bearing is optimized for medium-high speed and medium-heavy steady load operation. It adapts to frequent start-stop and long-cycle continuous running. It can withstand stable radial load and certain instantaneous impact load, perfectly matching the working cycle of large fans, industrial blowers and medium-power transmission equipment that run for a long time.
Q3: Why choose 6305-2RS contact seal instead of 2RZ non-contact seal for home appliances?
A3: Home appliances such as washing machines and large fans involve humid air, oil mist and fiber dust. Compared with 2RZ non-contact seal with weak protection, 6305-2RS contact rubber seal achieves full closed protection. It completely isolates fine pollutants and moisture, ensures long-term internal grease stability, and delivers far higher durability and anti-fouling performance in complex household environments.
Q4: What are the main failure causes of 6305-2RS in actual use?
A4: Most failures come from human mismatching rather than product quality. Overload operation beyond bearing capacity, long-term severe vibration, improper installation deflection, and working in heavy water immersion or strong corrosion environments
Q5: What typical equipment is 6305-2RS exclusively used for?
A5: It is mainly applied to core load-bearing positions that require high rigidity and stability, including large drum washing machine main spindles, high-power industrial fans and blowers, commercial drying equipment, medium-power industrial mixers, power tool transmission shafts and conventional medium-load motor spindles.
