The ultimate energy-saving design achieved by compact speed controllers

MBR (Mechanical Brake Roller) incorporates a speed controller which uses the centrifugal force generated in the arm as the gear amplifies roller rotation with load transportation.
Using no power source and relying on the force of gravity, MBR is the ultimate energy-saving brake roller.
This mechanism not only saves the operator’s labor but also allows the load to slow down gently without damage to it.
MBR can be used for various purposes including low-speed conveyance or prevention of uncontrollable operation in self-propelled conveyors, and speed reduction before a turnaround or transfer machine.

The industry’s first brake rollers for conveyor rollers with a diameter of 57 or 60 mm
Use the special mounting bracket for a small-diameter roller.

Features of MBR

  • ● Braking or deceleration automatically occurs when load
        speed exceeds a given level.
  • ● Can be installed just in a place where you wish to decrease
       the conveying speed.
  • ● No need for an electric power source or air source.
  • ● Safe conveyance without damage to loads
  • ● Useful for self-propelled conveyor lines. A wide application
        range.
       (Loads can be separated easily when combined with
        idle rollers. The conveyor angle can be set ;easily.)
  • ● Compact speed controller built in a pipe with a diameter
        of 57 or 60 mm –– first in the industry
  • ● User-friendly snap-on attachment
       (An idle roller with a diameter of 57 or 60 mm can
       be easily replaced with an MBR.)

The centrifugal force generated by roller rotation is used for automatic braking action.

Upgraded system

The MBR-JPR system combined with an automatic load separator assures higher efficiency. 使用用途の一例

MBRs are used in a variety of situations.

The system which combines MBRs with an automatic load separator assures higher efficiency.

Specification of MBR

■MBR Size-Weight Table

MBR Size-Weight Table

**The minimum roller width (RW) is 135 mm   (MBRs can be manufactured with sizes in millimeters.)

For roller widths less than 230 mm, consult us.

■MBR Withstand Load Table

MBR Withstand Load Table

Please select the roller whose withstand load is twice or three times the weight of the load, considering the surface condition of the load and an impact which may be generated when the load is placed on the conveyor.
Note: MBRs should be used within a temperature range of -5 to 40˚C.
