Full definition
Component that keeps rolling elements separated, equally spaced and guided within the bearing. Materials and applications: stamped steel (standard, economical), machined brass (high temperature up to 200°C), polyamide PA66 (high speed, low noise, lightweight), PEEK (>150°C, aggressive chemistry). Polyamide cages allow 20–30% higher speeds than steel cages. ISO 15 standard. Cage type influences speed limit and noise level.
