R4ZZ Deep Groove Ball Bearing

The R4ZZ bearing, a premium Small bearing and a prime example of our Deep groove ball bearing series, is meticulously engineered for high - performance applications. With precise dimensions of 1/4" (6.35mm) inner diameter, 5/8" (15.875mm) outer diameter, and 0.196" (4.9784mm) width, it epitomizes our unwavering commitment to precision. The ZZ - type metal iron covers, crafted from high - strength materials, provide robust protection against dust and contaminants, ensuring durability on par with our Stainless steel bearings. This makes the R4ZZ an ideal choice for small power tools requiring reliable operation in harsh environments, sewing machines demanding smooth and precise movements, models and toys needing long - lasting performance, and even Water pump bearings in compact systems where space is limited yet durability is critical.

Deep groove ball bearings, including the R4ZZ, form the cornerstone of rolling bearing technology. Capable of efficiently handling both radial and bidirectional axial loads, they are integral components in a vast array of machinery, fans, and motors. Like our standard Ball bearings, the R4ZZ offers high - speed rotation capabilities of up to 18,000 RPM, low friction coefficients as low as 0.0015, and excellent wear resistance with a hardness of HRC60 - 62. These characteristics make it suitable for demanding applications such as the high - speed motors in precision medical devices and the rotating parts of automated industrial equipment.

Beyond our standard offerings, we specialize in Non-standard bearing customization. Whether you require modified dimensions (inner/outer diameter, width) to fit unique equipment designs or specialized features like enhanced sealing for underwater applications, our team of expert engineers leverages advanced CAD/CAM systems and decades of industry experience to deliver tailored solutions. From Stainless steel bearing variants with corrosion - resistant 316L alloy for marine applications to unique Deep groove Ball bearing designs with optimized raceway profiles for reduced noise in high - end electronics, we ensure precision even in the most complex production processes. Our Non-standard bearing customization service has successfully delivered solutions for clients in aerospace, robotics, and renewable energy sectors, where off - the - shelf products cannot meet their specific requirements.
