Mighty Lube Products
Rarely is this a sign of a problem. Mighty Lube systems are designed to apply lubricant only as it is required and as it has been programmed to do. After completing the lubrication cycle, the lubricator goes into an “off cycle” for the specified number of chain revolutions. In certain applications, this may even be several days.
On enclosed track conveyors, typical lube time settings are around 10 to 15 milliseconds. Monorail and formed track conveyors require more because of the greater bearing surface to be covered, usually in the 15 to 25 millisecond range. Depending on various factors, these settings may be higher or lower. It is not recommended to go below 8 milliseconds to insure proper solenoid operation.
Frequency of lubrication is determined by many factors, including chain length, speed, heat and water. The general rule of thumb follows that slow moving conveyors and low to moderate heat conditions use one lubrication cycle for each eight hour shift that the conveyor is in operation.
Example: A 500′ conveyor at 10′ per minute would make 9.6 revolutions in an eight hour period. Programming 9 into the off cycles would cause the lubricator to activate once per shift. When changing off cycle settings it is recommended that the value not be changed more then 10% at a time and the new setting should be run for a few shifts to determine if further adjustment is required.
If a timer is used, any variation in the operation schedule can cause over or under lubrication. Some older timed systems that were not actuated by chain movement even come on when the conveyor is not running, causing the lubricant intended for the entire chain to be applied in one place. Mighty Lube equipment operates only while the conveyor is operating. By counting cycles instead of time, you are assured that the chain is lubricated as needed. This is a great advantage on conveyors with variable speeds and schedules.
On enclosed track systems, one solenoid had three tubes. These are aimed at the top of the link connectors and into the bearing opening on the horizontal bearings. The two tubes from the other solenoid are aimed into the bearing opening on the vertical bearings.
On monorail or formed track conveyor, the tops of the chain pins are aimed at with the tubes from one solenoid and the tubes from the other solenoid are aimed into the bearing opening on the trolley. Caution must be used when working in close proximity of the conveyor while it is in operation.
For conveyor safety regulations see OSHA’s Conveyor Safety Standards.
In order to quote the appropriate equipment for your application, we may ask for the chain size. The chain sizes that are most common are the x348, x458, and x678 chains. To determine your chain size, refer to the diagram below.
P = Nominal Pitch
X = Height of Center Link
L = Overall Pin Length
C = Length of Flat on Center Link
N = Thickness of Side Link
Mighty Lube and OPCO make products for a wide variety of conveyor types. When quoting products we will need to know your rail type. Below are some common types of conveyor rails, including: I-Beam (3 inch, 4 inch, 6 inch) and Enclosed Track (Richards-Wilcox, Unibilt/Rapid). If your rail differs from these types, please provide a photo and a detailed description of your rail when you request a quote.
Enclosed Track Rail Sizes
A (Width) 63mm
B (Height) 60mm
A (Width) 44 mm
B (Height) 59 mm
I-Beam Rail Sizes
3 Inch I-Beam = 76 mm
4 Inch I-Beam = 101 mm
6 Inch I-Beam = 152 mm
Since there are many different applications for conveyor systems, no single lubricant is appropriate for all applications. Mighty Lube and OPCO offer a wide variety of conveyor lubricants suited to many applications. Mighty Lube lubrication equipment requires a thin-film type lubricant to operate properly, while OPCO lubricators require high viscosity lubricants.
We will be happy to help you determine which lube is most appropriate for your needs. You may also refer to our Technical Data Sheets for further information.
