Table 2: Material Options for Deep Groove Ball Bearings
Material | Advantages | Disadvantages |
---|---|---|
Steel | High strength, low cost | Susceptible to corrosion |
Stainless Steel | Corrosion-resistant | More expensive than steel |
Ceramic | High strength, corrosion-resistant, low friction | Higher cost, more brittle |
Polymer | Lightweight, self-lubricating | Lower load capacity, less durable |
Table 3: Sealing Options for Deep Groove Ball Bearings
Seal Type | Advantages | Disadvantages |
---|---|---|
Open | No seals, low friction | Vulnerable to contamination |
Shielded | Single-lip seal, some protection against contamination | Less effective than full seals |
Contact | Single-lip seal with light contact on inner ring, good protection against contamination | Higher friction |
Non-Contact | Single-lip seal without contact on inner ring, high protection against contamination | Very low friction |
Double Contact | Two-lip seal with contact on both inner and outer rings, excellent protection against contamination | Highest friction |
