There are basically (3) classifications of conveyor rollers. Light-Duty, Medium-Duty, and Heavy-Duty rollers as described below:  

1.   “Light-Duty” conveyor rollers. These conveyor rollers are designed only for light use. The materials remain the same, either steel, aluminum or plastic for the body and its components, but they usually include non-precision roller bearings, and the roller diameter typically ranges from 1 3/8” to 2.5” and gauge thicknesses of 18 Ga. – 14 Ga. 

2.   “Medium-Duty” conveyor rollers. These usually include commercial, and precision bearings, and a roller diameter greater than that of a light conveyor roller: from 2.5” to 5” and gauge thicknesses of 11 Ga. – 7 Ga. 

3.   “Heavy-Duty” conveyor rollers. The roller diameter range is from 3.5” to 7.” Heavy duty rollers also have thicker tubes, with thicknesses of .300” to .500” wall. Generally these have more durable bearings and axle designs. 

Indoff, Inc supplies machine tolerance conveyor rollers, and fixed spindle pulley type rollers in both inch and metric dimensions. The following options are available:

·        Welded fixed spindles

·        Bearing confined, free turning shafts

·        Machined bearing seats for press-fit

·        Milled keyway for fixed spindles

·        Metric size tubing available

·        Metric shafts & spindles available

·        Rollers can be supplied with machined crowns

·        ABEC-1 precision bearings available

·        Roller shells, spindles, and bearings available in Stainless Steel

·        Machine ground coated rollers to your tolerances

Indoff, Inc provides solutions to some very special applications. The latest such solution involves handling drums of nuclear waste. The drums of waste in this application needed to be lifted & manually conveyed into a processing trailer. Drums enter on front end of trailer, where the nuclear material is processed, and then exits at the end of the trailer. Indoff, Inc engineered the following solution:

 1.   (2) Stainless Steel Hydraulic Scissor Lift Tables, totally rated for outdoor use. Both operated by (1) common Hydraulic Power Unit.

2.   (2) Stainless Steel heavy-duty gravity conveyor sections mounted to the top of the scissor-lift tables. Conveyor includes: Double-sealed roller bearings, roller tube, hex axles, and frame, all fabricated from 330 stainless-steel.

3.   Stainless steel pneumatic operated roller brakes, blade stop, and side guides.

Indoff, Inc also has precision crowned rollers primarily used as return rollers in belt conveyors. These rollers are precision ground to desired degree of taper from centerline of roller to bearing seat. (Both sides) Crowned rollers are normally used in belt conveyors with speeds exceeding 100 FPM. The main purpose of the crowned conveyor roller is to aid in belt tracking for higher speed belt conveyors.

• Sulfamate Nickel: an affordable electroless nickel coating, machinable for effective component repair
• Nye-Kote™: robust corrosion protection with thickness accuracy, friction protection and hardness performance
• Kanigen®: A well known corrosion protectant that bonds especially well to interior dimensions and intricate, hard-to-plate parts
• Electralloy™: a thin dense chrome finish that fights corrosion and wear better than traditional plating
• HVOF: Coatings applied with a technologically advanced spray system that maximizes density of deposits, bond strength, deposit thickness and surface smoothness

Wide Variety of Rollers and Components 

In order to properly convey the product smoothly and efficiently, it should be supported by a minimum of three rollers. To calculate the center to center roller spacing required, divide the length of your package by 3. The dividend is your required spacing. For example, a package 12" long when divided by 3 yields a dividend of 4. Therefore, the required spacing would be 4" center to center. Flexible bottom surfaces require four or more supporting rollers per package, calculating spacing would require the same procedure.
