Self-Aligning Ball Bearing 1308 K TV C3 NKE 40x90x23

Main Description

The 1308 K TV C3 NKE 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 TV C3 NKE combines a spherical outer raceway, tapered bore K, and C3 clearance to deliver flexibility and durability in demanding conditions. 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, providing installation versatility. The C3 clearance ensures safe operation at higher temperatures and speeds, while the TV cage made of polymer improves running performance and reduces friction.

The 40x90x23 size is widely used in medium-duty industrial applications where alignment precision is difficult to maintain.
