Key Design Considerations
The design of these seals directly impacts their performance in preventing dust, water ingress, and lubricant loss . Key factors include:
Seal Type: Common types are:
Contact Seals: The seal lip contacts the bearing rings, offering good sealing effect but higher friction. Suitable for applications with high demands for dust and water prevention, such as agricultural machinery .
Non-Contact Seals: The seal lip does not contact the rings, resulting in low friction but slightly less effective sealing. Ideal for high-speed, low-friction applications like electric motors .
