STANDARD COMBINED ROLLER BEARING - 4.057
This page is a summary of the products that can be used in conjunction with the 4.057 standard combined roller bearing (77.7mm OD). The 4.057 bearings are run inside an "I" or "H" section channel and, due to the compact design of the weldable hub, they are not normally used with mounting plates. If you want a bearing for a C section channel, then please see 4.056.
Originally used in fork trucks, combined roller bearings can be used in a variety of vertical & horizontal linear motion applications.
