Backup Roll with Shaft

The bearings for tension leveller machines are considered backup bearings. BMI manufactures a lot of sizes in different designs and configuration. BMI guarantees the perfect interchangeability with the original bearings.

Backup roller with shaft ensures wide working surface along with rolling system made of two or more cages allowing the plant to reach very high flattening performance at high speed. The distance rings allow a good support of axial loads.

The series of back up roller is usually manufactured with two lateral thrust bearings in the inner body either with ball or roller which guarantee a very strong support of axial loads.
