• Cylindrical roller bearings
• Deep groove ball bearings
• Electrically insulated bearings (coated outer ring or inner ring, hybrid)

Gearbox bearings

Gearbox bearings operate under high speeds and loads, must endure shocks, vibrations and high temperatures. The most frequently used bearing types for gearboxes are:

• Cylindrical roller bearings
• Tapered roller bearings
• Angular contact ball bearings

• Deep groove ball bearings

NKE bearings for gearboxes and traction motors are usually produced with special specifications (e.g. SQ1 for traction motors).
