Adapter Sleeves

Adapter sleeves let you mount a tapered-bore bearing onto a smooth, straight shaft without machining, using a tapered fit drawn up tight with a locknut and lockwasher. Off Road Belts stocks adapter sleeves in a broad range of inch and metric sizes to fit self-aligning ball and roller bearings, making them indispensable for line shafting, fans, and industrial drive assemblies. Match the sleeve to your bearing bore and shaft diameter for a secure, removable mounting that simplifies installation and future service.
