- Specifications
The shallow double beaded pans are recommended for heavy duty continuous service or for handling abrasive materials.
Pans are mild steel. Sidebars are medium carbon steel. Pins are thru hardened alloy steel for even more wear resistance. Sidebars and pins can be furnished with additional heat treatment on request. Bushings are furnished in case hardened steel to provide maximum wear resistance and chain life. Rollers are furnished in WEBLOY and provide a grease reservoir and lubrication fittings when internal greasing is required.
Apron conveyor chains are cottered construction.
Apron conveyor chains are interchangeable with other standard makes of corresponding sizes and numbers.
Aprons are used in conveyors and feeders where the most difficult operating conditions prevail. The rollers provide lower operating friction which helps to increase chain life and reduce conveyor design requirements.
Apron conveyors are best suited for slow or moderate speed applications. Maximum chain speed depends upon size of sprockets. For Conveyor Service see Table 2, Section A.
