SKF needle roller bearings SKF SD 20X28X4

Radial shaft seals with small cross-sections are used in bearing arrangements in combination with needle roller bearings. This contact seal is designed without a clamping spring. Type SD seals have a large primary lip and a smaller secondary lip for dusting. The sealing lip is made of polyurethane, and the reinforcing ring is made of nylon instead of metal.

  • Small cross-section
  • Keep the lubricant
  • Protects against contaminants
  • Provides additional protection through the secondary lip
