The SW 6212 ZZ is a standard series deep groove ball bearing engineered for high-precision, medium-load industrial applications. Featuring standard dimensions of 60mm bore (d), 110mm outer diameter (D), and a 22mm width (B), this robust bearing conforms meticulously to ISO standards, ensuring seamless interchangeability across all major machinery types. The 'ZZ' designation confirms the use of two non-contact metallic shields, factory-optimized to securely retain premium lithium grease while effectively excluding dry contaminants and dust, making it the preferred choice for environments where high rotational speeds and atmospheric contaminants are present. Manufactured exclusively from ultra-clean 52100 high-carbon chrome steel, it provides exceptional material hardness, fatigue resistance, and extended operational life.
Designed for maximum operational longevity, the SW 6212 ZZ delivers superior reliability across critical industrial systems, including high-power electric motors, industrial gearboxes, heavy-duty centrifugal pumps, and large conveyor systems. Its finely tuned raceway geometry and precision ball complement minimize friction and vibration, resulting in significantly reduced operational heat buildup and noise, ensuring compliance with strict industrial acoustic standards. Choosing the SW industrial standard guarantees superior service intervals and minimized unplanned downtime, actively protecting critical infrastructure through sustained, high-performance operation under demanding dynamic radial and axial loads.
