Self-Aligning Ball Bearing 1308 K TVH C3 FAG 40x90x23

Main Description

The 1308 K TVH C3 FAG self-aligning ball bearing 40x90x23 is a double-row bearing with a tapered bore and increased internal clearance, designed for reliable operation in systems exposed to misalignment, vibration, and variable loads.

Within the self-aligning ball bearings category, the 1308 K TVH C3 FAG stands out due to its combination of a spherical outer raceway, tapered bore K, and C3 internal clearance. The self-aligning design allows automatic compensation of shaft and housing misalignment, reducing stress and extending service life. The tapered bore enables mounting on adapter sleeves, offering flexibility in installation. The C3 clearance ensures safe operation under higher temperatures, speeds, or dynamic conditions.

The 40x90x23 size is commonly used in medium-duty industrial applications where alignment precision cannot be guaranteed.
