What CEMA ratings do you meet and what type of seal system do you have for the bearings?

I am in the salt mining business and materials of construction, load ratings and seals are the most critical to me.

Do you have a website that I could review your techinical specifications of your rolls? ■

What type of seal for the bearing??

Mr Will Justin

Please attach some photos, as a photo is more than enough a thousand words. ■

Agree with Harish. Please kindly also use a technical language instead of sales like your post and previous reply.

Rgds,

Endri ■

Idlers and rolls need to meet CEMA standards - so what bearing do you use to meet CEMA D rolls? What is the basic dynamic load of the bearing? Do you have a triple labrinth seal? These are all things that engineers and designers look at very closely when selecting a roll.

Factory bearing seals would never last a week in our salt environment.

Why are you relucting to provide us with techinical information?

You have a very strong sales pitch but no technical information to back it up.

How can you classify yourself as a manufacturer without providing techincal literature to possible users?

A quick little bit of research finds your company website at CW21 Inc. But yet there is no mention of conveyor rollers on your website. Do you have another company that is manufaturing the rollers? ■

Even outside the USA?? ■

Designer

Yes we follow CEMA in Canada.

Our conveyor design software that we use is all based on CEMA formulas.

Ah Canada, of course you would.

Europe may be a different proposition. ■

Would be interested in what you have to offer as compared to what is already out there. ■

Good day to all.

********************************I would like to thank you for the time in allowing me to introduce you to

my revolutionary design for conveyor idler roll heads. The concept allows for rolls from 3.5" to >9" to have just one head for the particular roll diameter to suit all applications from Impact to Catenary, Single End Mount and ALL Frame Mounts inbetween. In effect, there is one bearing pack only with one head Outside Diameter profile to suit 89mm, 104mm, 114mm, 127mm, 152mm, 178mm & 194mm plus other over size diameters. This reduces the Bearing with Seals inventory to one and the Head just varies the Outside Diameter with a single cross-sectional profile.

Adaptors are slip-on to suit every manufacturers mounting point or the use of link for catenary. The responce from the few manufacturers that I have approached have all stated that this head design will put existing through shaft or other idler rolls designs into the superceded category.

A standard roll will have only two well protected seals(1 per head). The loss of the through shaft reduces the mass but manufacturing equipment required would be less than US$200,000.00 for the full manufacturing equipment including a paint booth for full coat protection. Each end head mass is <2800grams and the Rim Drag in the mild steel prototype is approximately half 1/2 that of existing rolls from all tested major manufacturers. A 20 tonne press system is all the fabrication of the heads into the tubing shell. Collett lathes are required to cut the tube shell to length to meet all CEMA standard rolls or create special length rolls.

********The patent application is an 'Improved Stub Axle TechnologyIdler Roll'. A

confidentiality agreement will be required should you require further detail.

********I look forward to any comments for this innovation and to hearing from you.

********Once again, thank you for your time.

Regards
