Life sealed Idler Rollers are manufactured in ultra modern CNC machines.
The Idler Roller both ends are machined simultaneously in Double Headed Boring Machine, the Bearing cups are welded in Double Headed Boring Machine.
|
Bearing sealing area is machined and ground finished. Hence, these rollers are expected to perform extremely well Upto 40,000 Hours.
Turbo Idlers are manufactured to ISI / CEMA / ANSI / JIS standard to suit Global need.

The Turbo design utilizes circular plates that are submerged-arc welded to provide optimum rigidity and durability in high stress pulley applications. The end-disc plates are precision machined and then, the pulley is assembled and welded using a submerged-arc process.
The shaft is assembled with a tapered compression bushing or keyless locking assembly to ensure a precision mechanical lock between the shaft and pulley.
Finally, the pulley is then machined and / or lagged. This unique yet cost - effective approach has proven itself in hundreds of demanding installations for more than a decade.
Today, the Turbo engineered-class pulley has become an integral part of practical large-scale haulage systems everywhere in the world.

The Turbo Conveyor solid face pulley utilizes a single-piece rolled plate rim, continuously welded end-discs and extra strength intermediate discs, as required. Crown face pulleys are standard for diameters twelve inches and greater and are recommended for most applications. The Crown* is produced with special forming rolls assuring crown accuracy and rim contour. The crown design helps maintain belt alignment which is an important factor in belt life and operating efficiency of the conveyor system. Straight face pulleys are supplied for high-tension applications and for all tandom drives.
*Crown is defined as the amount (expressed in inches) per foot of total face width by which the diameter at the center exceeds the edge diameter. Turbo pulleys are crowned 1/16" to 1/8" on the diameter per foot of total face width.

Pulleys with vulcanzed rubber lagging are recommended when friction is desired between belting and drive pulley or when excessive foreign material on the belt surface causes pulley face build-up. Properly selected lagging can also effectively reduce abrasion and, with periodic replacement, not only extend the no-maintenance cycle, but eliminate the need for eventual pulley replacement due to rim wear.
Lagging can be furnished in various thicknesses. A 55-65 durometer hardness is suggested for most applications and is furnished as standard unless otherwise specified.
The addition of herringbone grooves or diamond grooves can be helpful on drive pulleys for medium and high-tension applications where water or surface build-up tends to reduce traction. Grooving provides improved belt cleaning characteristics, thereby maintaining maximum friction. The apex of herringbone groove pulleys should lead the direction of rotation, which must should lead the direction of rotation, which must must be specified if the pulley and shaft are to be factory fitted.
Note: All Pulleys are stress relieved.

The design of the Turbo engineered-class pulley incorporates end-disc fabrication methods which impart the exceptional strength and durability properties of cast or custom-machined end-discs avoiding the problems common to end-disc fabrication such as distortion and the creation of failure-prone "heat affected zones."
