Conveyor Covers

Protecting the belt as well as the bulk materials is important in the conveying industry. That’s why PPI offers conveyor covers. Built of galvanized steel, they will stand up to a multitude of environmental challenges. Choose full or three-quarter coverage.

Take-Up Frames

Take-Up Frames eliminate the need for additional take-up supports and enable load distribution. PPI offers a number of different styles and options, including those designed specifically for light duty, medium duty, or heavy duty.

Impact Beds

PPI Impact Beds are available in a variety of designs and configurations. The EZ Slider provides a variety of loading zone options and impact absorption for light to medium duty loads. PPI’s medium duty Slider Bed is a cost-effective solution combining impact absorption and belt support while promoting a tight seal against your skirting system. PPI’s Spring Impact Roll offers an impact solution that will adjust and flex as materials are being loaded on the belt. Finally, the True Impact System from PPI combines a proven impact roll along with a center support system, allowing for a double action dampening system. This addresses both the problem of sealing skirt boards and the impact on the belt.

Sanitary Conveyor Components

PPI is a premier manufacturer of sanitary conveyor components for the food processing industry. Their product offering includes a complete line of food grade stainless-steel conveyor drum pulleys. Also consider sanitary drive pulleys, sanitary tail pulleys, custom pulleys, self-leveling foot pads, and stainless-steel bushings.

Bearings

PPI offers a variety of bearings for diverse applications. Its SAFD bearings are ideally suited for heavy conveyor applications. SAFD housings are made from spherical graphite iron (ductile iron), which increases performance in colder temperatures. The rugged SCM bearings feature a nitrile contact seal that is effective in contaminated environments like those common in industry. The Type E pillow block bearing was designed for the challenges of multiple conveyor applications. It uses a double-row spherical bearing that makes a misalignment of ± 2 degrees possible, allowing the bearing to be more forgiving of mounting positions that are less than perfect. Additionally, a double lip nitrile contact seal provides the necessary protection for heavily contaminated applications.
