Material
The bearing’s main structure is crafted from high-grade 52100 chromium steel, offering excellent hardness, wear resistance, and load-bearing capacity to ensure long-term operational stability. The double seals are made of nitrile rubber (NBR), which exhibits good elasticity, oil resistance, and water tightness, effectively maintaining the integrity of internal lubrication.
Characteristics
1. Enhanced moisture resistance: The 2RS rubber seals form a flexible barrier against water splashes, condensation, and fine dust, making it ideal for semi-humid environments like kitchens or bathrooms.
2. Low noise operation: The rubber seals dampen vibration and reduce friction-induced noise, suitable for devices used in quiet settings such as residential or office spaces.
3. Lubrication retention: The seals effectively lock in pre-applied lubricating grease, minimizing the need for frequent maintenance and extending service life in enclosed assemblies.
4. Moderate speed adaptability: While providing superior sealing compared to metal shields, it operates smoothly at moderate rotational speeds without excessive drag.
Applications
1. Household appliances: Such as coffee machines, electric kettles, and bathroom exhaust fans, where protection against steam or water droplets is essential.
2. Personal care devices: Including electric toothbrushes, facial steamers, and hair curlers, benefiting from low noise and moisture resistance.
3. Outdoor small equipment: Like garden sprinkler motors, portable LED lights, and camping gear components, which may encounter light rain or dew.
4. Medical tools: Such as handheld nebulizers and small-scale liquid pumps, where preventing fluid ingress and maintaining hygiene are critical.
