Roller Universal Shafts

Roller universal shaft is a key transmission component in continuous production lines such as metallurgy and steel rolling, designed specifically for harsh working conditions such as high temperature, high load, and high dust.

core functionality

1. Angle compensation: allows adjacent roller tracks to have axis deviations within ± 15 °, adapting to equipment thermal deformation and installation errors.
   

2. Torque transmission: The rated torque covers the range of 5-500kN · m, meeting the power requirements of heavy equipment such as rolling mills and conveyor rollers.
   

3. Maintenance free design: Adopting a quadruple seal (lip seal+labyrinth structure) and self-lubricating bearings, achieving 1-2 years of maintenance free operation and reducing downtime losses.

Typical application scenarios include laminar cooling section of hot rolling production line, slab descaling system, etc., to reduce energy loss caused by abnormal shutdown.

Installation specifications

1. Coaxiality error ≤ 0.1mm/m, calibrated using a laser alignment instrument.
   

2. 10% travel allowance is reserved for the spline expansion part to compensate for thermal expansion.
