View ProductsTrough End
The screw conveyor trough end serves as an enclosure, conveyor support, screw support. The trough end attaches to both ends of the screw conveyor, at the top is flanged to support the cover, at the bottom acts as a foot to support the conveyor and in the middle has standard bolting for screw conveyor drives, end bearings and shaft seals. SCP offers trough ends for every screw conveyor size and in a few different configurations depending on the bearing or drive being used.
View ProductsShaft Seal
Screw conveyor shaft seals are used to prevent material leakage at the shaft penetration of the drive or tail shaft through the trough end. Often overlooked until there is a problem, shaft seals are available in a wide variety of configurations from the simple plate seal to more complex mechanical seals like the SCP Master Seal. SCP offers the most common shaft seals for screw conveyors for all the standard shaft sizes.
View ProductsShaft Bearing
Screw conveyor bearings are used to support the drive and tail end of the screw. The screw covneyor drive typically has the drive end bearign built in. Good practice is to use a ball bearing at the tail end of the screw conveyor to allow for any runout or misalignment of the screw. The flange bearing is the most common and cost effective. SCP offers bearings for both the drive and tail ends in all the standard shaft sizes.
View ProductsTail Shaft
The screw conveyor tail shaft is used to support the non-drive end of the screw, also called the tail. The tail shaft has botling to match the screw and is long enough to extend fromt he screw, through the trough end, through the shaft seal and to the ball bearing. SCP offers tail shafts in all the standard shaft sizes.
View ProductsInlet
The screw conveyor inlet is pre-sized to maximize the cross-sectional area of the product feed. The inlet is standardized based on the screw diameter and matches the discharge pattern to allow bolting of consecutive screw conveyors together. SCP offers standard inlets for every screw conveyor diameter and a convenient cover with an inlet already mounted for easy assembly.
View ProductsCover
The screw conveyor cover is one of the most important and sometimes overlooked features. The cover serves as an enclosure to elminate dusting, wheather intrusion and most importantly as a safety barrier to protect operators and manitenance personnel. The cover comes in standard 10ft lengths for 6in and 9in conveyors and 12ft lengths for convers 12in and above and can be easly cut to length in the field. SCP offers covers for every screw conveyor size.
View ProductsCover Bolting
Screw conveyor covers can be held to the trough with several different fastener options. The most reliable way is with bolts, although some facilities use screw clamps. Bolts offer the most protection for operators and maintenance personnel since they will not vibrate loose and require a tool to loosen and remove the cover. Most bolts are drilled on either 12in or 24in centers along both sides of the cover the full length. The spacing can be modified to fit specific needs. SCP offers pre-packaged bolting kits for screw covneyor covers for both 10ft (6in and 9in) and 12ft (12in and up) covers.
View ProductsHanger Bearing
Screw conveyor hanger bearings are friction bearings used to support long spans of screws. Hanger bearings are available in a wide range of materials and several configurations. The most widely used are style 226, sometimes called 220, with material of construction in Wood, UHMW, and Hard Iron. Hanger bearings require lower through loading to ensure product flows under the hanger bearing and not into it. These are a must part of any spare parts list. SCP offers both 216 and 226 style hanger bearings in a wide veriety of materials.
View ProductsHanger
Screw conveyor hangers are used to support the screw and allow for longer screw conveyors than could be accomplished with a 1-piece screw.
