1209 is a self-aligning ball bearing, 45 mm bore × 85 mm OD × 19 mm wide (1.7717 × 3.3465 × 0.748 in).
Self Aligning Ball Bearing 1209
The Self-Aligning Series 1200 & 1300 are engineered with two rows of balls sharing a common sphered raceway in the outer ring. These bearings feature a unique self-aligning capability, allowing for angular misalignment between the shaft and the housing. For applications requiring a tapered bore, the part number includes a 'K' suffix. This design is particularly advantageous in scenarios where misalignment may occur due to mounting errors or shaft deflection. Additionally, non-sealed self-aligning ball bearings in this series boast the lowest friction of any bearing type, enhancing efficiency and performance. If you're seeking sealed options, consider our 2200-2RS self-aligning series, which offers the same self-aligning benefits with the added protection of seals.
