Lutco is the largest manufacturer of flangettes in North America! 

Flangette assemblies are constructed as two piece, pressed steel housings, and are used in applications that require controlled torque and misalignment.

The spherical inside surfaces of each pair of flangettes mates with the spherical outside diameter of the bearing’s outer race to provide self-aligning capability.

Flangettes are offered in standard configurations as well as custom designs.  Standard flangettes configurations are offered in two bolt, three and four bolt round, triangular, four bolt square and relubricatable types. Custom or special flangettes can also be developed based on your requirements.
