Most people understand what a pulley is. They have been around for centuries. The simplest versions use a rope and chain to hoist different weights up, moving them from place to place without requiring excessive force or mechanics. Precision Pulley and Idler (PPI) have been providing industries from California to Texas with these devices since 1977. One of their industrial types is the single disc pulley.
Single Disc Pulley (SDE)
A single disc pulley consists of a single disc welded to the rim. Usually, of steel, this heavy-duty one-piece device combined with both a high compression bushing and hub is ideal for certain industrial work. Precision Pulley and Idler produce SDE pulleys with the following characteristics:
* All-steel construction
* Composed of standard crown face and XT® hubs
* Capable of reducing stress
* Decreases deflection
* This provides them with the durability to withstand rigorous demands.
Industrial Applications
The agriculture industry uses SDE pulleys – usually for the conveyance of grain. As a component of grain elevators, SDE pulleys act as grain elevators. The PPI single disc pulley most frequently is a component of vertical bucket elevators – the most common and oldest form of grain transportation in the industry. However, more recently, PPI pulleys are finding their place as part of agricultural grain conveyors, instead. Conveyors prove to be gentler in transporting the product. This opens another market for SDE pulleys, including that of related grain industries; including the production of grain-related products, e.g., corn sweetener and Ethanol.
The SDE Precision Pulley
Precision Pulley and Idler have a reputation for producing durable, rugged and functional products. Their line of pulleys includes drum, wing and disc. While some are more suitable for the mining industry, the most common use of the SDE Precision Pulley is in the agricultural industry. In Texas and other states, it is a common component of vertical bucket grain elevators where its quality and endurance serve it and the farmers who rely on it, well.
