Product Introduction
A double row self-aligning ball bearing is a double-row ball bearing with self-aligning capabilities, suitable for mechanical equipment such as fans and pumps where shaft misalignment or heavy loads are common.
Product Features
Automatic Self-Alignment Performance: The spherical outer ring raceway of the double row self-aligning ball bearing allows for slight tilting of the inner ring, compensating for shaft misalignment of 2-3°, ensuring smooth shaft operation.
High Wear Resistance: The double row self-aligning ball bearing is made of GCr15 or AISI 440C steel, with precision-ground balls and raceways, resulting in a service life of up to 10 years.
Precision Machining: The inner and outer rings and balls of this ball bearing have a tolerance of ≤0.01 mm, ensuring smooth operation with low vibration and noise.
Low Maintenance Requirements: This ball bearing is pre-filled with high-temperature lithium-based grease, allowing for continuous operation for 1-3 years without frequent lubrication.
