Screw Conveyor Hangers and Hanger Bearings
Screw conveyor bearing hangers are manufactured to hold and support the conveyor screws and are typically accompanied by a bearing within it that will allow for the free spin of the screw. Screw conveyor hangers are supplied with a lubrication pipe or without, the ones with a lubrication pipe typically utilize a Babbit bearing, bronze bearing, or ball bearings, but other bearing types are available upon request. We supply screw conveyor hanger assemblies for standard and heavy-duty abrasive applications for standard and flared conveyor trough types. Depending on the hanger style, bearing options such as hard iron, manganese, ceramic, wood, bronze, Babbitt, white Nylon, nylatron, and Gatke are readily available. We can also supply these hangers manufactured from special materials such as stainless steel for specific applications.

Screw Conveyor Hanger Types
Type 220 Hanger:
This hanger style is one of the most common types because of its design, which offers the least amount of possible obstruction in material flow. The design also features wide top bars for better stability when mounting across trough flange points. Standard bearings used in a 220 screw conveyor hanger include babbitt, hard iron, Arguto, wood, bronze, Nylon, or Nylatron; additional special order options include bronze Oilite, Gatke, Stellite, Teflon, or any other conceivable bearing material.
Type 226 Hanger:
Style 226 screw conveyor hangers are the most commonly used hanger type because of a design that offers the least amount of possible obstruction in material flow and because it mounts completely inside of the trough, making it suitable for dust-tight and weather-tight covers. This style is also designed with wide top bars for better stability when mounting across trough flange points and a grease fitting port for re-lube. Standard bearings used in a 220 screw conveyor hanger include babbitt, hard iron, Arguto, wood, bronze, Nylon, or Nylatron; additional special order options include bronze Oilite, Gatke, Stellite, Teflon, or any other conceivable bearing material.
Type 230 Hanger:
Type 230 conveyor hangers are designed for the most severe and rugged applications; they typically are supplied with hard-iron bearings, but Arguto Wood bearings are also available. This style features wide top bars for greater stability when mounting across trough flange joints.
Type 216 Hanger:
Type 216 hangers are designed to allow them to be mounted inside the trough, making them suitable for applications that require dust and or weatherproof covers. This style is designed for heavy-duty and rugged applications and utilizes wide top bars for greater stability when mounting across trough flange joints. They typically are supplied with hard-iron bearings, but Arguto Wood bearings are also available.
Type 260 Hanger:
Type 260 hangers operate quieter and require lower power inputs due to the use of self-aligning ball bearings. Typically this type is utilized in long screw conveying applications that operate at higher speeds but are not recommended for applications with dirty, gritty, or abrasive materials. Alemite bearings are generally furnished in these hangers, they can also be referred to as "lubed for life" bearings. 260 hangers utilize a wide top bar design for greater stability when mounting across trough flange joints, this is particularly important when using self-aligning ball bearings.
Type 270 Hanger:
Type 270 hangers operate quieter and require lower power inputs due to the use of self-aligning ball bearings. Typically this type is utilized in long screw conveying applications that operate at higher speeds but are not recommended for applications with dirty, gritty, or abrasive materials. This design is typically preferred because it allows for mounting to occur completely inside the trough, allowing weatherproof and/or dustproof covers to be utilized if necessary. Alemite bearings are generally furnished in these hangers; they can also be called "lubed for life" bearings. 270 hangers utilize a wide top bar design for greater stability when mounting across trough flange joints; this is particularly important when using self-aligning ball bearings.
Type 326 Hanger:
Type 326 hangers are designed for use in applications conveying hot materials for lengths consisting of three or more screw sections. The top bars are designed in a way that allows them to freely slide on the angle guides, compensating for any unequal expansion between the trough and screw conveyor. The 326 is designed to fit within the trough beneath the forever and is suitable for use with a dust-tight or weather-proof cover. The special design also offers minimal resistance to material flow, and removal bearings made of special materials can be furnished for specific application requirements. Premium hard-iron bearings and hardened steel conveyor couplings will be furnished unless otherwise specified.
Flared Trough Type Hanger:
Flared trough hangers are made for flared troughs and can be furnished in any hanger style offered, or specially designed hangers can be supplied upon request to meet exact application requirements.
Standard bearings used in flared trough hangers include babbitt, hard iron, Arguto, wood, bronze, Nylon, or Nylatron; additional special order options include bronze Oilite, Gatke, Stellite, Teflon, or any other conceivable bearing material.
