KOYO 1200 Self-aligning Ball Bearings 调心球轴承 10 × 30 × 9 mm

Overview

KOYO 1200 Self-Aligning Ball Bearing uses two rows of balls and a spherical outer ring raceway to compensate for shaft misalignment. It provides low-friction rotation in fans, conveyors, textile machines, and long-shaft arrangements with mounting or housing deviations.

Two rows of balls are guided by a cage on the inner ring, while the outer ring has a spherical raceway. The design absorbs angular misalignment between shaft and housing while maintaining low friction at moderate to high speeds.

Selection guidance

Check expected misalignment, load, sealing needs, internal clearance, and available mounting space.
