Idlers

TIS (Trougher Impact System)

True Impact System

Xtend the Life of your Belt.

Double-action shock absorption

Fold down wings for ease of installation and maintenance

Low drag

Offset rolls to reduce roll gap at the center

Built-in slots for hoist, crane, or fork truck

1/2” thick UHMW for long life and increase effectiveness in skirt board sealing

The Trougher Impact System is designed to match with CEMA standard dimensions. Each system is setup on CEMA D6 and E7 standards to maximize the impact absorption. If your requirements are for C5, D5, or E6, contact PPI about our Low Profile Impact System (TISL).

In the close-up (bottom left) you can see what makes the TIS so unique. Each roll is fitted with a rugged 2 inch, 1045 shaft end to act as a knuckle, pivoting as the roll moves. This design will take the abuse of impact, and make it easy to replace the roll.

The second part is the black round cylinder, under the roll supports. This is a rubber marshmellow, that will absorb the shock from impact.

TROUGHING IDLERS
Precision® Idlers are available in CEMA B, CEMA C and CEMA D series. The "B" series are available 4" and 5" diameter rolls with 17 mm ball bearings. CEMA C series idlers are available in 4", 5" and 6" diameter rolls with either 3/4" ball bearings or 3/4" tapered roller bearings. CEMA D series idlers are available in 5" and 6" diameter rolls with 3/4" tapered roller or 1" ball bearings. CEMA E series idlers are available in 6" and 7" diameter rolls with 1 11/16" ball bearings.

E - IDLERS
CEMA E series idlers are available in 6" and 7" diameter rolls with 1 11/16" shaft and 6308 ball bearings with our triple action seals.

IMPACT TROUGHING IDLERS
Precision® Impact Idlers are built to withstand the shock at the loading zone. The rubber rolls used on impact idlers are made of natural molded rubber which is ideal for shock absorbing characteristics.

UNEQUAL TROUGHING IDLERS
PPI Unequal Idlers (or picking idlers) are available special conveyors where the product is spread over a flat belt with the side turned up to prevent spillage.

UNEQUAL IMPACT TROUGHING IDLERS
Precision® Impact Idlers are built to withstand the shock at the loading zone. The rubber rolls used on impact idlers are made of natural molded rubber which is ideal for shock absorbing characteristics.

SELF-ALIGNING TROUGHING IDLERS
Precision® Self-Aligning Idlers are built to the same specifications as troughing idlers. The frame is mounted on a separate base with tapered roller bearings, and it is free to swivel within controlled limits. A unique feature of this style is its ability to adjust roll height for additional training. The side guide rolls can be universally mounted on either side for belt travel in either direction or centered at the roll ends for reversing belts.

FLAT CARRIER IDLERS
Precision® Flat Carrier Idlers are constructed to the same specifications as the troughing idlers. The support bracket's strength is equal to or greater than the idler load rating. Precision furnishes 4 ½" end stands as standard. If a different height is required, please contact the factory.

RUBBER DISC FLAT CARRIER IDLERS
Rubber Disc Flat Carrier Idlers are made of abrasion resistant, synthetic rubber with an encapsulated steel ring which maintains a compression fit between a heavy wall tube and the disc

SELF-ALIGNING FLAT CARRIER IDLERS
All of the features that are designed into the Self-Aligning Troughing Idlers will be found in this idler style too.

ADJUSTABLE PITCH IDLERS
The ability to change the pitch of the idler allows the conveyor belt to be properly supported as it changes shape from the last carrying idler to the terminal pulley. This idler is available in all CEMA series and roll diameters.

RETURN IDLERS
Precision® Return Idlers are available in CEMA B with 17 mm ball bearings. CEMA C Return Idlers are available with 3/4" ball bearings or 3/4" tapered roller bearings. CEMA D series are supplied with 3/4" tapered roller re-greaseable bearings or 1" ball bearings. Standard drop brackets are 4 ½" unless 1 ½" drop brackets are requested.

RUBBER DISC RETURN IDLERS
Rubber Disc Return Idlers are constructed from abrasion resistant, synthetic rubber discs. An encapsulated steel ring maintains a compression fit between the disc and a heavy wall inner tube.

SELF-ALIGNING RETURN IDLERS
Precision® Self-Aligning Return Idlers are comprised of a two piece frame with tapered roller bearings, and it is free to swivel within controlled limits. The side guide rolls can be universally mounted on either side for belt travel in either direction or centered at the roll ends for reversing belts.

SELF-ALIGNING RUBBER DISC RETURN IDLERS
All of the features that are designed into the Precision® Self-Aligning Return Idlers will be found on this idler with the addition of a rubber disc roll.

CHANNEL INSET TROUGHING IDLERS
Designed for between frame mounting, Precision® offers this style for use where vertical clearances are minimal. This style meets CEMA load requirements and is available in both CEMA B (14"-48") and CEMA C (24"-60") with 4" and 5" diameter rolls.

RETURN ROLL GUARD
This guard provides a barricade of the pinch point created by the belt passing over a return roll. Its mounting bracket provides easy installation on 4", 5" or 6" rolls with 4 ½" drop brackets utilizing the return bracket's mounting bolts. While normally used on return rolls with seven feet or less vertical clearance from the ground or decking, it may be used on any return roll. Note: Also available in 1 ½" drop brackets and in HD type for D Rolls and extra belt sag.

SMART ROLL
The redesigned Smart Roll has AC / DC / NPN / PNP operation from the same unit. This unit has short circuit and overload protection. Sensor life and reliability are extremely important to overall reliability of the conveyor system. The smart roll option is now exclusively offered in a select range of our CEMA "D" Idler product line. The added life of the CEMA "D" ensures excellent reliability and maximum sensor protection in most applications. Our new sensor takes advantage of the latest sensor technologies for unsurpassed sensing reliability. The extended range and unique target design combine to make missed or lost target sensing a thing of the past. Our new Smart Monitor is available to attach to any of our new "SA" Smart Rolls. The Smart Monitor can act as a under speed switch for your conveyor system. The Smart Roll is shown to the left as a CSR (Clean Side Return) with no load, so that the roll life is many times that of a conventional idler.
