Call us for personal assistance to select the right low profile, drum motor, or electric shaker conveyor to meet your needs.
We offer a comprehensive line of low-profile, under-die slug conveyors and parts handling conveyors from Pax Products.
2018 Pax Bulletin – PAX Bulletin 550
The “low-profile” conveyor design enables it to fit where many conveyors will not. Specifically designed for on-bolster, under-die part and scrap removal, the patented conveyors are built to survive the rough metal stamping environment.
The standard drive arrangement is designed for the motor end of the conveyor to set on the bolster, inside the bed area of the press. This eliminates the need for extra guarding and does not interfere with existing guarding. Other optional drive arrangements include:
Designed to hang over the end of the bolster, the standard tension end is only 2.5” high. An optional flush mount tension end is available for applications where the tension end must lay flat on the bolster.

Additional Options
Pax EGD Conveyors
The Pax EGD conveyor is an electrically driven, oscillating type conveyor that utilizes a motorized, elliptical gear drive (EGD) to produce a reciprocating, varying acceleration motion that conveys parts and scrap out of the press area. Utilizing elliptical gears provides an extremely reliable, high torque design that has 4 times the acceleration rate of a standard linkage design. This higher acceleration provides a higher conveying speed at a lower motor speed, which results in increased unit life. Other key features of this product include:
Standard System Features Include:
• No Air Consumption
The EGD conveyor is electrically driven which means that it does not have the high operating costs and on going maintenance issues that are associated with many air driven conveyors.
• Conveying Speed of Up to 25 Feet Per Minute
On air driven conveyors, the user will typically reduce the conveyor’s speed to the absolute minimal acceptable level for each application in an effort to reduce air usage and to extend air seal life. However, since these are not relevant issues on an electrically driven conveyor, the EGD conveyor is designed to run at the fixed speed that has been determined to be its ideal conveying speed.
• Flexible Mounting Arrangement
There are four (4) 3/8”– 16 tapped holes located on the bottom of the EGD unit that can be utilized to attach the unit to one of Pax Products optional mounting brackets or to any other type of mounting arrangement.
• Quick and Easy Tray Attachment
Trays are attached to the EGD Conveyor cross bar via quick connect brackets. These brackets, which are machined from Acetal material, are bolted to the sides of the conveyor tray and the tray then simply snaps in place over the round portion of the conveyor cross bar.
• Low Maintenance
The EGD conveyor utilizes no springs and requires no ongoing maintenance. Refer to following section for more details on the system construction.
System Construction and Specifications:
Elliptical Drive
The EGD conveyor is driven by a set of elliptical (non-circular) gears. The first elliptical gear, which is driven at a constant speed by an electric motor, drives a second elliptical gear at a continuously changing speed. The two gears are in constant rolling contact and are bathed in oil inside of a sealed gear box. This design provides a maintenance free, high torque, varying speed transmission that provides an excellent conveying motion for the attached trays.
Guiding System
The conveyor crossbar is guided by four linear, sealed for life bearings that are spaced as far apart as possible in both the right-to-left and front-to-back directions. Although the bearings are sealed for life, Pax has arranged them so it is possible for the customer to easily grease them (at their discretion), which will further extend the bearing life in severe operating conditions.
Cross Bar
The rigidly designed steel crossbar can be provided in different length as defined in the option section of this proposal.
Quick Connect Tray Mounting Brackets
Each EGD conveyor is provided with three sets of quick connect tray mounting brackets. Each set includes two machined Acetal brackets and four ¼”-20 carriage bolts with nuts and washers. Additional bracket sets can be purchased as described in the options portion of this proposal.
Pax EGD Conveyors
The EGD conveyor is currently available in three sizes, which are rated based on the total tray weight (this does not include the weight of the parts and scrap on the trays).
EGD-50: can hold up to 50 lbs of tray weight PLUS parts
EGD-125: can hold up to 125 lbs of tray weight PLUS parts
EGD-250: can hold up to 250 lbs of tray weight PLUS parts
EGDF Floor Mount Conveyor up to 500 lbs of parts and scrap
Cross Bar Length: Standard Lengths are 18”, 24”, 30”, and 36”
Max. Total Tray Weight: 50 pounds not including parts and scrap.
Max. Part/Scrap Weight: 100 lbs (not including Trays)
Control: No control is required. Unit plugs directly into a 3-pronged, 120V outlet
Cross Bar Length: Standard Lengths are 24”, 30”, 36”, 48”, 60”, 72” and 84”
Max. Total Tray Weight: 125 pounds.
Max. Part/Scrap Weight: 250 lbs (not including Trays)
Dimensions of Drive Unit: 7″ High x 20″ Wide x 15″ Deep
Weight of Drive Unit: 95 pounds (not including cross bar, options, or packaging)
Control: Variable Frequency Drive (VFD) is remotely mounted.
Motor Type: 3/8 hp AC, Gear motor
To help reduce small slugs and dirt from getting into the conveyor unit, a stainless steel plate is attached to the bottom of the conveyor crossbar and the plate (shield) moves with the crossbar. This plate extends beyond all four sides of the conveyor, completely shielding the top surface of the EGD unit.
Several sizes and types of brackets are available, contact Pax for further details.
Pax EGD-125
Pax EGD-125 with Tray
Cross Bar Length: Standard Lengths are 6’ to 16’ in 6” increments
Max. Total Tray Weight: 250 pounds not including parts and scrap
Dimensions of Drive Unit: 12″ High x 72″ Wide x 18″ Deep

Motor Type: 3/4 hp AC, Gear motor
This conveyor is designed to be a cost-effective alternative to the typical hinged belt and/or magnetic conveyors. The design allows it to be mounted below a press and it will operate a single conveying tray that will convey material away from the conveyor drive.
The Pax floor mount conveyor is often used in conjunction with a cleated belt conveyor to move scrap from floor level to a scrap bin.
Pax EGD 250 Floor Mount Conveyor
PaxEGD-250 VFD Drive
The Pax Model DMC “Drum Motor” Conveyor is designed for removing parts and scrap from dies. This low-maintenance conveyor utilizes a geared motor hermetically sealed inside a steel cylindrical tube. This technology eliminates the need for chains, sprockets and external motors.
