SKF bearing descriptions follow a structured alphanumeric designation system (e.g., 6208-2Z/C3) detailing type, size, and internal design. The basic designation identifies the bearing series and bore size, while prefixes and suffixes indicate material, sealing, cage design, clearance, and lubrication, allowing for precise specification in engineering applications.

Common SKF Bearing Types (Prefix/Series):

  1. 6...: Deep groove ball bearings (e.g., 6208).
  2. 2...: Spherical roller bearings (e.g., 22216).
  3. N...: Cylindrical roller bearings (e.g., NU, NJ, NUP).
  4. C...: CARB toroidal roller bearings.
  5. 7...: Angular contact ball bearings.
  6. T...: Tapered roller bearings.

Key Designation Suffixes (Design/Features):

  1. Sealing: -2Z (shields on both sides), -2RS1 or -2RSH (contact seals).
  2. Clearance: C2 (smaller than normal), CN (Normal), C3 (greater than normal), C4.
  3. Cage: M (machined brass), TN9 (glass fibre reinforced polyamide).
  4. Internal Design: E (optimized internal design), K (tapered bore 1:12).

Examples:

  1. 6208-2Z/C3: Deep groove ball bearing (6208), shields on both sides (2Z), and larger than normal clearance (C3).
  2. 22216 EK/C3: Spherical roller bearing (222), optimized internal design (E), tapered bore (K), and C3 clearance.
