1215 K Bearing Structural Features & Performance Benefits
Double Row Design: Provides enhanced radial load capacity compared to single row bearings, making it suitable for applications with significant radial forces.
Nylon Cage Construction: The polymer cage offers excellent strength-to-weight ratio, reduced friction, and quiet operation at high speeds up to 6,700 rpm.
Precision Tolerances: Tight dimensional tolerances (bore: -0.015mm to 0, OD: -0.018mm to 0) ensure precise fit and reliable performance in precision applications.
Chrome Steel Construction: Both rings and balls manufactured from high-grade chrome steel provide superior durability and wear resistance across the operating temperature range of -30°C to 110°C.
