  • Breakthrough Bearing Protectors For Harsh Environments
    Bearing protectors are basically bearing covers that provide a very minute space between the outside bearing race and the bearing protector itself. Most commonly used with spherical bearings that use an excentric locking collar. The bearing protectors are made special for each bearing brand, style
  • Bearing Materials
    components is 58 R . Less hardness allows the races to Brinell. Since hardness decreases with increasing temperature, conventional bearing steels such as 440C and SAE 52100 cannot be used much above 350 F. have received much attention in an effort to develop steels suitable for high-temperature bearings
  • Ball vs Sleeve: A Comparison in Bearing Performance
    systems can generate enough heat to destroy years worth of work. A design engineer needs a reliable fan that will maintain system cooling and protect against system meltdown. Most engineers believe that a quality axial fan is the answer to this threat. Yet, many engineers debate over which bearing
  • Polymers enhance race-car performance
    piston, O-ring groove, and bearing groove. Top right: New Arlon damper piston with ACT and Ener-Cap seals. In racing, a split second can make the difference between winning and losing, or between a serious accident and a trouble-free ride. That's why race teams in CART, Formula 1, Indy Car, and NASCAR
  • Using Eddy Current Test Techniques to Verify the Number of Bearings in a Bearing Assembly
    techniques to "count" the number of bearings that are present in a race or bearing group. This system operates as follows: 1. A probe containing an eddy current coil, that has been properly sized for the inspection to be conducted, is inserted into a bearing subassembly that has a full compliment
  • Why is My Bearing Cracked?
    In this issue of NPBâ s e-News we are presenting an article on a specific design feature of industrial spherical bearings. This article introduces the common feature of cracked races from both the assembly and application perspective. From time to time our sales and product group take calls from
  • Induction Heating Helps Put Wind Turbines in High Gear (.pdf)
    Accurately controlled induction heat treating systems are effectively used for induction hardening large gears and bearing races utilized in wind energy applications producing the required metallurgical properties with minimum shape distortion, providing high quality parts that directly affect
  • Linear-Bearing Design Considerations
    Hardness, finish, and conformity of race and rolling elements determine load capacity, which varies as the fourth power of the race Brinell hardness number. The surface finish must be smooth because grinding marks create ridges that prevent conformity between the race and rolling element
