Material
The bearing’s core components—inner ring, outer ring, and rolling elements—are constructed from high-grade 52100 chromium steel, ensuring excellent hardness, wear resistance, and dimensional stability to handle continuous rotational loads. The 2RS seals are made of nitrile rubber (NBR), which offers good elasticity, oil resistance, and water tightness, effectively sealing the bearing interior against moisture and debris.
Characteristics
1. Enhanced moisture resistance: The flexible rubber seals form a tight barrier against water droplets, condensation, and humid air, making it suitable for applications exposed to occasional dampness, such as kitchen appliances or outdoor tools.
2. Low noise operation: The rubber material dampens vibration and reduces friction-induced noise, making it ideal for devices used in quiet environments like homes or offices.
3. Lubrication retention: The seals effectively lock in pre-applied lubricant, minimizing the need for frequent re-lubrication and extending service life in hard-to-maintain assemblies.
4. Compact versatility: Its small size allows easy integration into space-constrained equipment, while supporting reliable performance under light to medium radial loads in diverse environments.
Applications
1. Household appliances: Such as coffee machines, blenders, and humidifiers, where protection against liquid splashes or steam is essential.
2. Personal care devices: Including electric shavers, hair dryers, and facial steamers, leveraging low noise and moisture resistance.
3. Outdoor small equipment: Like garden sprinkler motors, portable fans, and camping gear components, which may encounter dew or light rain.
4. Medical tools: Such as portable nebulizers and small liquid pumps, where preventing fluid ingress and maintaining hygiene are crucial.
