ENGINEERED CLASS DRUM CONVEYOR PULLEY

Bulk handling systems are moving to larger conveyors and increased capacities. The high modules, high tension belts require pulleys of much higher capacity and durability than standard units. precision® has the experience, know how, and equipment to custom design (using our PFEA in combination with our IP-Life model), and fabricate pulleys for each pulley location and application. Precision Engineered Class Pulleys are supplied with various hub and bushing systems including keyless locking devices used on profiled and cast disc designed pulleys, which are prevalent on high tension steel cable belt systems.

EZ MOUNT PULLEY SYSTEM

This unique pulley and shaft arrangement allows for fast, safe, and economical bearing and shaft replacement without removing the pulley from the conveyor. It reduces maintenance time, downtime, and scrap loss by using rugged engineered stub shafts. The pulley and shaft system is manufactured to CEMA standards and Mine Duty specifications.

DUAL DRUM CONVEYOR PULLEY

The precision® Dual Drum Pulley has proven in material handling installations where belts create excessive loads which cause excessive shaft deflection and premature pulley failure of Heavy Duty Drums or Mine Duty Drums. Designed to decrease shaft slope at the hubs, decrease stress at all end disc weld locations, and eliminate pre-stressing of end discs during assembly with tapered type hubs.

“SDE” SINGLE DISC ELEVATOR PULLEY

Superior strength best characterizes the precision® “SDE” Single Disc Elevator Pulley. Used primarily in the grain industry, the “SDE” Single Disc Elevator Pulley, with continuous weld on the disc to the rim on both sides of the disc, coupled with heavy duty construction and a high compression hub and bushing affords a one-piece all steel, single disc pulley capable of reducing stress and deflection. The “SDE” Pulley is constructed with a standard crown face unless otherwise specified. Standard diameters range from 16” thru 42” and standard face widths 8” thru 1

LAGGED IDLER ROLLS

Idler rolls are available in SBR, Neoprene, White Neoprene, and Urethane, in thicknesses from 1/8” to 1/2”.

HD Idler Rolls (H)

PPI Heavy Duty Rolls come with 1/4" cans. To specify a 1/4" thick can, just add H to the beginning of the part number, e.g. D6-FL-48SB becomes HD6-FL-48SB

.

Poly Sleeve Roll Covering (PS)

PPI's Poly Sleeve Roll Covering is currently available for 6" diameter rolls only, it adds 5/16" thickness of Polyethylene to the idler roll. The Polyethylene improves corrosion resistance, reduces friction and yields additional wear to a Precision Idler. To specify a poly sleeve roll, just add PS to the end of the part number, e.g. D6-FL-48SB becomes D6-FL-48SBPS

INVERTED V RETURN

Inverted V Returns are used to positively track the belt by creating a displacement force on the belt. As long as the belt is centered, these displacement forces will balance out. If the belt is off, just a fraction of an inch, the displacement forces will be unbalanced, creating a centering force, moving the belt back towards the center. That is positive tracking! There is no waiting for the belt to wonder off track far enough to activate a passive training system. Available in CEMA C & D, 5 & 6 Roll Diameter 4.5 inch drop and CEMA E 6 & 7 inch roll diameter 7 inch drop for standard belt widths.

BEATER BAR RETURN IDLER ROLLS

Designed to drop into the PPI Heavy Duty Drop brackets. The roll is available in 5 and 6 inch diameters in CEMA C & D configurations. The part number use FLBR type identifier, e.g. C5-FLBR-24SB. This part includes 2 end clips and screws. The HD drop bracket is available separately as part number 14205.

RETURN IDLERS

precision® Return Idlers are available in CEMA B, C, D & E with Xtra Heavy Duty Sealed Ball Bearings. Standard drop brackets are 4 ½” unless 1 ½” drop brackets are requested.

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

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.

TEISW (Trougher Equal Impact Slider Wing)

To expand the functionality of our idlers, precision® announces the development of our
Wing Slider System. Slider brackets can be installed in precision® frames to replace the wing rolls. This helps the skirtboard sealing and is meant to compliment the TIS and TISZ systems, to aid in sealing the belt between the slider rails and the skirtboards adjacent to the loading area. precision® recommends using a minimum of 3 idler frames. However the system is flexible enough to use from 2 to 5 frames with each section. Reduced drag - 70% .of the load is on the center roll. Improved Impact absorption - Rubber discs are better for absorption of impact.. Improves Skirtboard sealing effectiveness. Assembles in place for ease of installation. Standard 1/2” thick UHMW - optional 1” thick UHMW. Standard 5 foot rails, also available in 4 foot lengths.

TISZ (Trougher Impact System)

Our TIS has been so popular will solving loading problems, that we have expanded the line with the 2 foot option. The 2 foot system is designed for underground mining where there is not room to install a one piece 5 foot system, AND for transfer points on any conveyor. Transfer points often have a well defined stream, and a 5 foot system is not necessary. However both systems, the 5 foot and 2 foot have the same features:

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 & TISZL). Our prototype is still running after 6 years, without a single roll or UHMW failing.

TROUGHING IDLERS

Precision® Idlers are available in CEMA B, C, D & E series. The “B” series are available 4” and 5” diameter rolls. CEMA C series idlers are available in 4”, 5” and 6” diameter rolls. CEMA D series idlers are available in 5” and 6” diameter rolls. CEMA E series idlers are available in 6” and 7” diameter rolls.

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.

LAGGING FOR CONVEYOR PULLEYS

precision® has complete in-house pulley lagging capabilities. Every step of the pulley manufacturing and lagging process is controlled internally which assures quality, prompt delivery, and competitive pricing of lagged pulleys. Available in a wide variety of styles and thickness, lagging is primarily used to improve traction capacity, resist abrasive conditions and extend pulley and belt life. The style of lagging is required is usually influenced by operating conditions.

CHEVRON GROOVE LAGGING

Some prefer having the points meet, as done in Chevron, over HBG style shown above. This is also used primarily on drive pulleys. (3/8” minimum thickness)

DIAMOND GROOVE LAGGING

Diamond , or double HBG, or double chevron is primarily used for reversing conveyor drive pulleys. It is also often used for spare pulleys, when one doesn’t know what the direction of rotation. (3/8” minimum thickness)

CRAFT-LAG® REPLACEABLE LAGGING

Craft-Lag® is bonded to rigid backing which is then formed to a specific diameter. Craft-Lag® can be used with or without retainers and is ideal for mining, crushed stone, sand and gravel, cement, agriculture, food processing, coal mining, power plants, feed and grain, and general industry.

CERAMIC LAGGING

Ceramic lagging is rubber with ceramic tiles embedded into it. This makes for excellent traction, and abrasion resistance. This is used on larger drives.

ROUGH TOP LAGGING

Rough Top is used for small diameter drive pulleys, where the wear is not a problem. It is created by lagging the pulley, but before the rubber is cured, a special mold is applied to the lagging to cause the grooves to be formed in the lagging, and it is cured with this form in place. It gives excellent traction, without cutting grooves. This makes it available on thin lagging, such as 1/4.”

XHD FAS-LAG® REPLACEABLE LAGGING

This easy to install wing pulley lagging system is designed for the Quarry Max Wing pulley. It is welded to the flat contact bar to provide additional traction, protection for the contact bar and protection for the mechanical splice. The lagging is 2” wide by 1” thick to provide extra life. The standard is black 60 durometer SBR.

SHAFTS

precision® Conveyor Pulley Shafting is a vital part of the total pulley application. Standard Precision Shafting is AISI 1045, which represents the higher carbon range in the open hearth carbon group. Excluding alloy steel, higher carbon content in a AISI 1045 results in one of the strongest steels in the carbon range and machines to a smooth finish. Other alloys, including 4140 are available upon request. Shafting can be keyed or journaled to meet any specification
