Engineered Solutions - Down Time Virtually Eliminated

A local manufacturing company was having problems with slitter and guide rolls. The greasy, grimy and dirty environment was causing contaminates to fall into the bearings, and as the swarf built up the bearings froze ultimately cutting the slitter and guide rolls. The bearing boxes were getting so chewed up they needed replacement time and time again.

The customer's mill was shutting down almost four times per week creating backlogs and frustrated tier 1 customers. So Harbor, in partnership with the customer, designed a protective barrier that would prevent the bearings from the elements. The shield was installed and immediately the customer saw results. By keeping the swarf off the bearings it allowed the line to run continuously and hasn't shut down for the same failure since 2007.

Result:
Annual Savings $150,000+

Our customer has saved over $150,000 annually just by not having to replace the slitter and guide rolls. Additional savings have been realized due to the virtual elimination of downtime over the past few years.

New Equipment Retrofit to Meet Customer Needs

A local Tube Mill purchased a $750,000 saw and as is often the case, began having problems with the gear box soon after the warranty expired. The saw was breaking down two to three times per week so Harbor's engineering staff began working on the root cause - the gear box.

After diagnosing the gears to be too soft and gear ratio too small, Harbor specified a hardened gear and a ratio large enough to handle the tensile strength needed in the application. Testing proved that their solution was working. All they needed now was a new bearing box so Harbor built them one of those as well.

Result:
Annual Savings - Priceless. ZERO breakdowns since 2008.

Replacement Parts No Longer Needed

The customer was having continuous wear issues with their 9' long x 10" o.d. shafts. The shafts were wearing in a 2' section but the entire shaft was being scrapped. They were averaging three per month at $5,000 a piece, resulting in expenditures upwards of $250,000 annually.

Because the shafts were only wearing out in a small 2' section, there was no need to scrap the entire 9' shaft. Harbor suggested trying a keyed-in sleeve, welded into place and machined down to size - all being done at Harbor.

After establishing the sleeve specs to a higher ultimate tensile strength and testing, the shafts were put back into production without any interruptions of production.

Result:
Annual Savings $150,000+

The customer went from buying three new rolls at $5,000 each every month to repairing the existing rolls for $500 each, but needing only two per month because of the hardened sleeves.
