FAQ

Can I replace a stamped pulley with split metal?
     Not only can split steel replace stamped, but split steel is a cost-effective upgrade in quality. The groove section of a split steel pulley is uniformly formed from a single piece of solid plate steel. Split steel pulleys run truer than their two-piece stamped counterparts and there are no spot welds or rivets to fail.

Can I email prints?
     Yes. This is actually preferred and will help communicate your needs. Prints can be emailed in PDF, DXF, and DWG formats.

What is component consolidation?
     There are many applications that use two or three components that can be cast or machined as one to reduce assembly and manufacturing costs as well as reduce fit issues and human errors.

What is the relationship between balance–vibration and RPMs?
     Balance is actually measured as amount of unbalance that can be tolerated. This is weight multiplied by distance. RPM is not relevant to balance it is only relevant to vibration. Vibration is effected by axial and radial fit between components among many other product related features.

What is your quality policy?
     Our quality policy follows the ISO 9000 philosophy and has written process controls as standard operating procedures. More importantly we stand behind what we sell.

Where can I find Diamond Precision Products’® pulleys and components?
     Industry standards can be found at your local Blain (Farm & Fleet) Supply store, AFT Associate member, or contact us for an industry specific distributor.
Industry specific components can be found by contacting Diamond Precision Products® for design assistance or to quote your specific print for production run pricing.

What is Commercial Zinc?
     Commercial Zinc is the name or label given to a zinc finish specification that is commonly used in finishing metal parts. When specifying “Commercial Zinc”, you get a basic range of zinc finish protection. The normal composition has a thickness of .0002” (two ten thousandths of an inch) of zinc applied electrostatically.

Should I use Commercial Zinc as a final finish?
      Commercial Zinc is normally used for indoor applications or as the base coat for a more protective top coat such as paint. Finish protection normally increases with increasing thickness.

Will paint adhere to a zinc finish?
     Yes. Paint will adhere to a zinc finish. The use of zinc as a base or primer coating for painting is very common. The protective value of the combined finishes
(zinc + paint) normally gives excellent protection to the base metal.

Why is salt spray testing used?
     Salt spray testing is a means to measure the relative protective value of a particular finish. The American Society for Testing Methods (ASTM) salt spray specification B 117-90 is a detailed testing method for controlling the amount of salt spray solution, at what temperature, in what direction and much more. The results, normally in hours of exposure, allows for comparison of different finish formulations.

Will more finish protection cost more?
     YES! You get what you pay for. A good manufacturer will make sure you pay for what you need.
