1. Dimensions
It shares the same compact dimensions as its non - stainless steel counterpart, with a bore diameter of 1 mm, an outer diameter of 3 mm, and a width of 1 mm. This ultra - small size allows it to be integrated into the most space - constrained miniature mechanical systems.
2. Material
• Inner and Outer Rings: The inner and outer rings of the S601XZZ bearing are made from high - quality 440C stainless steel. 440C stainless steel is a martensitic stainless steel with excellent corrosion resistance, enabling the bearing to resist the effects of water, moisture, and some mild chemicals. It also has high hardness after heat treatment, providing good wear resistance and ensuring the bearing's structural stability during long - term operation.
• Balls: The balls inside the bearing are also crafted from 440C stainless steel. They undergo precision grinding to achieve a smooth surface and accurate spherical shape, which is essential for reducing friction between the balls and the raceways. The use of 440C stainless steel for the balls ensures that they, like the rings, have good corrosion resistance and wear resistance.
• Shields (ZZ): The double shields, marked as "ZZ", are made of stainless steel. These stainless steel shields not only prevent dust, dirt, and other small particles from entering the bearing's internal components but also contribute to the bearing's overall corrosion resistance. They are thin yet strong, fitting tightly around the bearing to provide effective protection without hindering rotation.
3. Performance
• Corrosion Resistance: The most notable performance feature of the S601XZZ bearing is its excellent corrosion resistance. Thanks to the 440C stainless steel material, it can operate reliably in wet, humid, or even mildly corrosive environments where non - stainless steel bearings would quickly rust and fail. For example, in a high - humidity industrial setting, this bearing remains unaffected by moisture, ensuring consistent performance.
• Load - Carrying Capacity: Despite its small size, it has a decent load - carrying capacity. The combination of the high strength of 440C stainless steel and the deep - groove design allows it to handle both radial and light axial loads. It can effectively support the rotating shafts in miniature equipment, such as small water pumps and precision medical devices, ensuring stable operation under normal working loads.
• Rotational Speed: The S601XZZ bearing is capable of operating at relatively high rotational speeds. The smooth contact between the stainless steel balls and raceways, along with proper lubrication, minimizes friction, enabling efficient rotation. It can reach rotational speeds suitable for micro - motors and other small - scale rotating components, ensuring efficient power transmission.
• Temperature Resistance: It exhibits good temperature resistance, able to operate within a certain range of temperatures. It can withstand low - temperature environments without losing its mechanical properties and can also perform stably in moderately high - temperature conditions, making it suitable for applications with temperature variations.
4. Sealing
The double stainless steel shields provide effective sealing against the ingress of dust, dirt, and other solid contaminants. They also offer a certain degree of protection against moisture and water splashes, although they are not completely waterproof. The shields help retain the lubricant within the bearing, ensuring that the internal components are properly lubricated for smooth rotation. This sealing performance enhances the bearing's reliability in various environments.
5. Applications
• Food Processing Equipment: In the food processing industry, where hygiene and corrosion resistance are crucial, the S601XZZ bearing is widely used. It can be found in small - sized food conveyors, mixers, and filling machines. For example, in a small yogurt filling machine, it supports the rotating parts, ensuring smooth operation and resisting corrosion from the yogurt and cleaning agents.
• Medical and Pharmaceutical Devices: Many medical and pharmaceutical devices rely on this bearing. In small - sized medical pumps used for drug delivery, it ensures the stable rotation of the pump's internal components, guaranteeing accurate drug dosage. In laboratory equipment such as small centrifuges, it can withstand the humid environment and ensure smooth operation.
• Marine and Aquatic Equipment: It is suitable for use in marine and aquatic equipment. In small - sized marine sensors, it supports the rotating parts, resisting corrosion from saltwater and ensuring accurate data collection. In small aquarium pumps, it operates reliably in water - related environments, helping to circulate water.
• Outdoor Electronics: Outdoor electronic devices such as small weather stations and environmental monitors use the S601XZZ bearing. It can resist the effects of rain, moisture, and other outdoor elements, ensuring the smooth operation of the devices' rotating components, such as fans or sensors.
