Plummer blocks of series SD 31 TS are used for large
spherical roller bearings of Series 231xx CK with
adapter sleeves. They are equipped with two labyrinth
sealing collars having a push fit on the shaft. A rubber
O-ring is fitted between the collar and shaft to ensure
rotating together.
Special bosses are provided on the lower half of the
housing to allow easy modification for oil lubrication.
The bosses can be drilled and tapped to take an oil
level gauge and drain plug. An oil circulating system
can also be connected. The housings can carry
very heavy loads and are designed for heavy duty
applications. In severe condition, taconite seal is
available to exclude fine abrasive dust and to retain
lubricant.
