Brass Rub Block Kit
Rub block, Inspection Door, Gasket, Shim, Bolts and Washers
RB2W4LR2

Brass rub blocks help monitor belt misalignment in bucket elevators and conveyors by detecting heat generated from the friction caused by a misaligned belt rubbing against the brass surface.

A temperature sensor embedded in the brass block measures the heat, and the system triggers an alarm and shutdown once the temperature reaches a trip-point.

Typically, these sensors are installed in pairs on opposite sides of the machine to detect misalignment on both sides. They can be connected directly to a PLC input or, for enhanced safety, integrated with an independent monitoring system such as 4B’s T500 Elite Hotbus™, Watchdog™ Super Elite, or T400N Elite Hotswitch.

Inspection doors are available for easier periodic maintenance and testing of the brass rub block and system.
