Conveyor Roller Classifications

Mon, 19 Oct 2009 11:21:56 CDT

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.

Extremely Special Roller Sections

Mon, 22 Jun 2009 11:36:06 CDT

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.

Precision Crowned Conveyor Rollers

Tue, 02 Jun 2009 11:07:15 CDT

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.

Corrosion Resistant Roller Coatings

Mon, 04 May 2009 15:59:12 CDT

Superior corrosion-resistant coatings with added benefits Corrosion resistant coatings from Electro-Coatings protect metals from corrosion, and give a valuable bonus: extra performance attributes that fight friction, minimize wear and help components maintain precise tolerances. The biggest bonus of all is the application expertise of an Electro-Coatings specialist, ready to sift through multiple options to find the best balance between quality and cost effectiveness.

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

Calculating Roller Spacing

Tue, 17 Feb 2009 17:16:19 CST

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.
