Achieve 100% Hardness Inspection of Ball and Roller Bearing Components
|
From Uson, L.P.
Bearing components can have hidden structural problems that will shorten product life. Improper heat-treating can ruin an entire production batch. One bad part in a bearing can ruin that bearing prematurely. Once an undetected bad bearing is installed in a larger assembly, your warranty liability increases further. When a Zetec Automated Bearing Hardness Inspection System is in place, every bearing can be tested without production line slowdown. That makes zero defects not just a goal but also an affordable reality.
Non-Stop Hardness Testing. Uson’s Zetec eddy current test system with “dynamic throughput” can evaluate all bearing components for hardness during the actual manufacturing process. More than 25,000 bearings/hour can pass through encircling coils that detect conditions such as short or no heat treatments, improper quench or material mix. Eddy current testing is specifically tailored to provide maximum detection while achieving maximum production throughput. The test procedures can also conduct real-time process validation without waiting for sample tests or destructive tests of bearings.
Products & Services
Thrust washers are used as a bearing surface for rotary applications. They are usually made of steel, bronze, plastic, or other material with low friction coefficients.
Bearing retainers or bearing cages are used in rotary and linear bearings to separate and maintain a specified distance between rolling elements, whether they are balls, needle rollers, or rollers.
Hydrostatic and hydrodynamic bearings are fluid film bearings that rely on a film of oil or air to create a clearance between the moving and stationary elements.
Jewel bearings, jewels and pivots are miniature components used in instruments and controls requiring low friction, long life and non-magnetic properties.
Specialty rotary bearings are specialized or proprietary rotary products and accessories related to roller bearings.
