Greetings and salutations SGanesh,

I added a few pictures and some notes on roll sizers and belt feeders for you to look at.

When I was taking care of number of underground conveyors by myself it amounted to greasing the idlers once a year and the greasing the tail pulley and drive unit pulleys every week along with checking oil levels, after almost a year I finally convinced the people in charge to use grease cups on the bearings and save money by doing so.

The biggest problem was grease hoses broken between the idler rollers and that problem was only addressed when a large number of idlers went bad on that particular belt and were changed-if we had only had the mechanical belt lifter that is available now back then-as the hydraulic take up had to be released if we were close to the drive unit or we used pry bars to lift the belt up otherwise.

If the return idlers were bad they quite often fell out of the stands holding the idler as the bearing went bad and fell apart etc. ■

Hi Ganesh,

We generally greasing all our conveyor pulleys bearings once in a month.

In equipments like stakers we have centralised greasing unit.

Critical areas we go for oil flushing once in 3 months. ■

The best greasing interval should be frequent but small in quantity, by maintaining the grease level in ideal quantity the contaminants cannot go inside the bearing. Contamination is one cause of bearing failure, having an automatic lubricator can check contamination, maintain grease in optimom level, no overgreasing / under greasing to worry.

This polling business is a tedium. You say you want to know the industrial standards. Kindly refer to the manufacturers' lubrication schedules! Why ask for votes from peolpe who might not adhere to the definitive literature which is available? ■

One of the poll options is ".......... based on bearing condition" & 40% of the repondents voted for this option. I rest my case! ■

MEMOLUB in Precise, Reliable & Economical.

MEMOLUB HPS prevent bearing failure by providing the right amount of

lubricant (cartridge - clean/fresh) at the right frequency to the right

place all the time. By keeping the grease in optimum level the bearing is

sealed from contaminants (dust, water), there`s no overheating, no under and no over lubrication.

MEMOLUB HPS offers superior features than Manual Lubrication. The

benefits includes less downtime due to bearing failure, reduced man-hours

required for the lubrication task, savings from spare parts, saving from cost of labor, workers safety and hygienic environment.

About Memolub:

The MEMOLUB® lubricator is an autonomous single/multi point

electro-mechanical lubricator. Its high lubricant ejection pressure of 25

bars opens a new wide range of applications not possible with conventional

systems. Memolub HPS can be used remotely up to 12 meters from the

lubrication point. Remote installation avoids dangerous or difficult

access points and maintenance personnel can work swiftly in safety.

Machine stoppage for lubrication (impossible access, moving components,

etc) can be avoided by installing Memolub HPS. Memolub HPS can also be

used as a mini central lubrication system. Combined with progressive

distributor blocks Memolub HPS multipoint lubrication is a simple,

economical way of reducing maintenance costs.

How it works:

Memolub®HPS is a fully self-contained electromechanical lubricator which

utilizes a patented positive displacement pump.

The main components are a motor, gearbox, piston pump, microprocessor and

a 4.5v battery power pack. A cam fitted to the outlet gears drives a

lever, which lifts the hollow piston and simultaneously compresses a

spring. When the piston reaches the top of its stroke, the lever is freed

from the cam and the piston begins its downward (working) stroke, driven

by the spring. Lubricant is sucked into the chamber formed above the

piston during its downward ejection stroke preparing it for its next

cycle.

The cycle interval and output quantity can be easily setup using the memo

fittings.

As you may know, all bearings will eventually fail before their L10 Life

running hours (2 years and below). One of the main causes of early bearing

failures is poor lubrication and dirt contamination. Lubrication failure

will lead to excessive wear, overheating and bearing breakdown.

If you have difficulties in getting your workers to lubricate certain

bearings:

Which require frequent re-lubrication.

Are isolated; are difficult to access.

Requiring machine stoppage for re-lubrication.

Memolub® HPS is here to solve your problems. Some of the advantages of

the Memolub® HPS system:-

*High pumping Pressure, 25 Bar (>350 p.s.i.)

*Single or multiple (12) points.

*Many choice of lubrication programmes.

*Cyclical pumping avoids oil separation and clogging.

*Simple rapid check function

Application:

Memolub HPS is extensively used in a wide variety of industrial application.

- Conveyors (drives, take-ups and idlers)

- Pumps

- Electric motors

- Bridge and Stacker Cranes

- Air make-up units

- Roof fans

- Air Handling Units

- Waste water equipment

- Cooling Towers

- Production equipment of all kinds

- Heat treat furnaces

- Coal-handling equipment

- Paper mill equipment

Dear Sganesh,

Please see attached file. We use small ring to adjust the volume output, you can see it clearly in this website

href="http://www.memolub.com" target="blank">www.memolub.com, on the second column and under Automatic Lubricators and Lubrication. Without this timing ring the ejection volume is fix to 0.635cc. The big 3 rings (black, red, white) are for frequency. If we attach the 3 rings together it will eject 24 times a day or equal to 15.1cc in one day, Red & White will eject 12 times a day, Red Black 4 times, Red alone will eject 2 times....

The MEMO is a unique system for adjusting the daily grease output of the MEMOLUB®. The MEMO is programmed the first time and is then permanently fitted on the lubrication point. Any MEMOLUB® will respect the setting of any installed MEMO.

Because of this programmable features of Memolub, the grease inside the bearing can be maintain in ideal quantity and by having this the dust or contaminants cant go inside the bearing thus prolonging the life of the bearing. The best example can be seen in this site

href="http://www.memolub.be/application.php?" target="blank">http://www.memolub.be/application.php? a single point application on conveyor.

If you want pictures of different application I can email it to you. If you want cost reduction use Memolub.

Dear Sganesh,

For us in Memolub, if your bearing don`t last a minimum of 2 years you have lubrication problem.

We need to maintain the bearing in excellent quality always and the only way to do it is to have a proper lubrication using Memolub.

Try one unit and compare to the one you are using right now.

Best regards,

DANNY REYES

Hi there,

I am a string proponent of condition based maintenance. There is a really cheap and yet effective method to re-grease bearings. Use an Ultra-Lube acoustic attachment for the grease gun and you can literally listen to how much grease it takes to provide sufficient enough lubrication.

Check out Noria's web site. They have really awesome technical papers and plenty of ideas and gizmos to offer for any lubrication situation.

This is one of their case studies dealing with re-greasing bearings.

Human commit mistakes, very hard to supervise, get tired. If you have thousands of bearing to re lubricate, they will do what is easy for them not for the benefit of machine. You can ask your lubeman now, how many cc or grams he inject to a certain machine, usual answer is until the old grease comes out which is bad. And even how religiously do your re lubrication still a lot of breakdown will re occur. Production losses, spare parts, cost of labor at the end you don`t get it cheaper. At this time of crisis, we need to save, need to innovate. Install Memolub especially to those machines that breakdown frequently.
