Screw Conveyor Trough Ends
Trough ends are manufactured from heavy gauge steel to very close tolerances. Assembly and mounting holes are precision cut to ensure correct alignment with trough end flanges.
KWS stocks a large inventory of trough ends in both carbon and stainless steel construction that are ready for immediate shipment. Stock trough ends are available with hole patterns for 4-bolt flange mounted ball and roller bearings.
Nomenclature
Note: Torque Arm Trough Ends include Drive Size before bearing call-out. (i.e: TETAO92U-SK3-RB)
Without Foot
Trough ends without feet are typically used in applications where a screw conveyor is suspended above ground and is supported from the top flange.

With Foot
Trough ends with feet are the most commonly used type of trough end, and are typically used in applications where a screw conveyor is mounted directly to the floor or on structural supports.

Pedestal
Pedestal trough ends are typically used in heavy- and extra-heavy-duty applications where a split gland, flanged gland or mechanical seal is required. Pedestal trough ends require the use of a pillow block bearing. The space between the trough end and pillow block bearing prevents contamination of the bearing.

Flush End
Flush End trough ends are used with flush end discharge spouts where overall length needs to be minimized and conveyance length needs to be maximized. The bottom flange of the flush end trough end is drilled to match the discharge flange pattern.

Bulkhead
Bulkhead trough ends are used with flange mounted gear reducers on the drive end of a screw conveyor and are typically used in heavy- and extra-heavy-duty applications where a split gland, flanged gland or mechanical seal is required. The space between the trough end and bulkhead prevents contamination of the gear reducer. A bulkhead drive shaft is required.

Torque Arm
Torque arm trough ends are used with pillow block bearings and shaft-mounted gear reducers on the drive end of a screw conveyor and are typically used in heavy- and extra-heavy-duty applications where a split gland, flanged gland or mechanical seal is required. The space between the trough end and pillow block bearing prevents contamination of the bearing and gear reducer. The special torque arm design allows the gear reducer to float freely on the drive shaft. A torque arm drive shaft is required.
