THD Series Non-Split Type Plummer Block Housings

The Plummer Block, as known as (Split/Non-Split) Plummer Block Housing, which is an assembly comprising of a self-aligning ball bearing or spherical roller bearing placed in bearing boxes of various shapes, has a large load capacity and is easy to handle, therefore it is widely used in general industrial machinery such as conveyors.

THD Take-Up Housings are non-split housings which are designed to accommodate heavy loads acting in different directions. These types of loads are typically encountered in conveyors, roller beds and crushers.

THD series Bearing Housings are widely used for take-up pulley for conveyor belt tensioning application. At top & bottom of the housings, suitable grooves are provided to facilitate smooth sliding of THD take-up unit on the guide rail. At one end, suitable fork arms are extended to facilitate use of anchor pin for fitment of screw for tightening the belt.

THD housings are non-split type with covers at both sides. The bearing can be mounted on Adapter Sleeve in general. Upon demand or as per application, THD housings can also be supplied for directly mounting bearing on the shaft. They are available for locating & non-locating bearing arrangement.

THD take-up housings are supplied with Taconite Seals or Labyrinth Seals as standard, but other sealing configurations can be easily be adapted. To protect the bearing in dusty & damp environment, the cavity of labyrinth seal are filled with grease while initial assembly.
