Bearing Cages
Bearing cages are essential components of rolling bearings, designed to guide rolling elements (balls, rollers, or needles) and maintain their correct spacing. This ensures smooth motion, reduces friction, increases bearing life, and provides reliable machine operation even under demanding conditions.
Cages are manufactured from different materials depending on the application requirements. The most common types include steel cages, brass cages, and polymer cages. Each material offers unique benefits – steel provides strength and durability, brass withstands higher temperatures and speeds, while plastic cages offer low noise, reduced weight, and corrosion resistance.
- Steel cages – high strength and excellent wear resistance
- Brass cages – suitable for high speeds and elevated temperatures
- Polymer cages – lightweight, quiet operation, corrosion resistance
Bearing cages are widely used across various industries, including automotive, aerospace, engineering machinery, and heavy industry. Choosing the right cage type significantly improves bearing performance, increases operational reliability, and extends service life.
