Los cojinetes de chumacera, el tipo de unidades montadas más comúnmente utilizado, son carcasas que tienen un cojinete instalado en ellas.
Están diseñados para brindar soporte al eje donde la superficie de montaje es paralela al eje del eje.
Fabricado típicamente de hierro fundido o acero fundido, el alojamiento del cojinete de la chumacera tiene provisiones para permitir que el alojamiento se atornille cómodamente.
