When it comes to motion solutions, the difference between original and imitation can make or break your operations. Copycat products may seem like an affordable alternative, but the hidden issues they bring—ranging from inconsistent quality to lack of engineering support—can lead to downtime, inefficiency, and unexpected costs.
For 75 years, Bishop-Wisecarver® has been a trusted leader in motion technology, delivering consistent quality and reliable solutions that stand the test of time. Our expertise, certified materials, and comprehensive support ensure your equipment performs at its best—because when precision and performance matter, there’s no substitute for the original.
Consider the following problems with copy products:
Inconsistent Sources
• Wheels can come from a multitude of plants with varying quality of machines and control processes.
Bishop-Wisecarver’s consistent quality for 75 years speaks for itself.
Inconsistent Quality
• Quality variation is not only an issue between manufactured lots, but also within wheel lots, which can leave you with broken equipment.
• Contact angles range from 7 degrees to 40 degrees, creating unpredictable load handling capabilities.
Bishop-Wisecarver wheels have the same contact angle lot-to-lot every time, yielding reliable load handling capabilities.
Questionable Metallurgy
• Inconsistent steel sourcing leads to inconsistent quality.
Bishop-Wisecarver bearing steel comes only from certified steel mills.
• Variation in steel leads to early wear and more downtime.
All of Bishop-Wisecarver’s steel is certified to AISI standards for metallurgical content and performance.
Lower Loads and Lower Life
• Controlled testing has shown that knockoff wheel suppliers regularly perform 40-60% below Bishop-Wisecarver’s wheels.
Bishop-Wisecarver’s wheels have extreme linear life, allowing for consistent and reliable operation of your equipment.
