  • Bearing Materials
    Bearings materials are classified as through-hardened materials (used largely for ball bearings) and case-hardened materials (used largely for roller bearings). Critical applications require vacuum-processed steels. Regardless of material type, a commonly accepted minimum hardness for bearing
  • Hybrid Ball Bearings
    NPB Bearings: * miniature & instrument * ball bearings * aerospace bearings * spherical plain * nu & nx bearings * thin section bearings * bearing tools * needle bearings. For most ball bearing applications, steel balls are sufficient. As applications become more complex and specialized
  • Bearing metrics for budget-minded projects
    and seals, cage type, noise level, and lifetime, all within the context of anticipated loads, speeds, and operating environment. First, look at bearing materials. SAE 52100 chrome alloy steel and its equivalents are used in most standard ball bearings. A fine microstructure and the ability to be ground
  • Glossary of Caster Terminology
    a Delrin Bearing (Plastic) can be used where non-stainless steel roller or ball bearings would rust. Stainless steel bearings are available but can be very expensive. All bearings can help reduce the friction caused when a wheel rotates while under a load. Bearings reduce the effort required to push
  • OEMs look to distributors for better service
    as assembly and warranty information. Case in point: A small OEM that builds rope sheaves used in paper-mill dryer sections had recently changed a bearing spec from two single-row, deep-groove ball bearings to a double-row, angular-contact ball bearing. The update looked great on paper, but end users
  • Basics of Design Engineering: Bearings
    , two-row miniature guideways made from stainless steel. An advanced ball-retainer design simplifies assembly and The minirail guideways come in 7, 9, 12, and 15-mm sizes. Available lengths range from 360 to 950 mm. Two preload and accuracy classes are available. Product dimensions conform to DIN 645
  • Medical Device Link .
    payload capacity for precision applications. The tabletop unit uses stainless-steel helicoil inserts to protect mounting holes from thread wear. �The ATS1000 lends itself to the precise positioning required by the manufacturers of various medical devices,� says Ron Rekowski, director
  • Quick-Action Couplers
    is permissible. They are suitable for vacuums down to 10 >= torr. On pump supply lines, a size should be selected that will not produce about 1.5-psi pressure drop at required flow. A wide variety of seals and materials are available for these couplers: carbon steel, stainless steel, brass, aluminum
