FAQs

  • What direction is an axial load applied?
  • The axial load is applied through the axis of the ball bore.
  • What is the axial static load capacity of Aurora Bearing Company's rod ends?
  • For Aurora two-piece rod ends, the maximum axial static load capacity is recommended to be 15% of the ultimate radial static load capacity. For three-piece rod ends, the maximum axial static load capacity is recommended to be 10% of the ultimate radial static load capacity. However, on three-piece units, factors such as race material, body material, and dimensions may affect the axial static load capacity. For further information, consult the Aurora Bearing engineering department.
  • What is the axial static load capacity of Aurora Bearing Company's spherical bearings?
  • The maximum axial static load capacity on Aurora spherical bearings is recommended at 20% of the radial static load. Extreme care should be used on selecting a sufficiently strong housing to accept this type of bearing.
  • What direction is a radial load applied?
  • The radial load is applied through the axis of the shank of the male or female body.
  • Is there a safety factor included in the ultimate radial static load capacity?
  • You should assume that there is no safety factor. The bearing will fail at the advertised load.
  • What is axial play (endplay)?
  • The measurement of the total range of movement of the ball inside the insert/body in the axial direction or the clearance measured along the axis of the ball bore.
  • What is radial play?
  • The measurement of the total range of movement of the ball inside the insert/body in the radial direction or the clearance measured along the axis of the shank of the male or female body.
  • What maintenance do I need to perform on my rod ends and spherical bearings to keep them operating properly?
  • For metal-to-metal rod ends and spherical bearings, a thin layer of grease applied occasionally to ball outside diameter will assist in extending the life of these products. Rod ends and spherical bearings that are Teflon lined are self-lubricating and are designed to be maintenance free and should not be lubricated.
  • What is the minimum thread engagement required to support the advertised load ratings in the Aurora Bearing Company catalog?
  • The minimum thread engagement is 1.5 times the major thread diameter unless otherwise stated.
  • What is the thickness of the Teflon liner?
  • The thickness of Aurora Bearing Company’s "AT" series Teflon liner is between .012"-.016" thick depending on which liner is chosen.
  • What is the maximum rpm's that a rod end or spherical bearing can operate at?
  • When a rod end or spherical bearing is to be applied in full rotation, the surface speed of the ball should be kept below 20 feet per minute or the rotational speed should be below 100 RPM, whichever is lower, with the operating loads not to exceed 10% of the ulitmate radial static load capacity.
  • Is Aurora Bearing Company ISO 9001 Certified?
  • The quality management system at Aurora Bearing Company is certified to ISO 9001:2000 and AS9100 (with design). Click here to view our certifications.
  • What is the operating temperature of Aurora Bearing Company's Teflon lined bearings?
  • Commercial grade liner = -65°F to +250°F
    Military specification liner = -65°F to +325°F
  • How much corrosion resistance does Aurora Bearing Company's zinc plated rod ends provide?
  • All zinc plated rod ends are plated to meet or exceed the requirements of ASTM B 633.
  • Does Aurora Bearing Company offer 2D and 3D drawings of their bearings?
  • Yes, they can be found under the "CAD Drawings" heading on the web site. Click here to view our CAD Drawings.
  • Does Aurora Bearing Company offer custom or made to order bearings?
  • Yes, Aurora Bearing has the ability to manufacture many types of specialty bearings not listed in the catalog. Please contact an Aurora Bearing Sales Representative for more information. Click here to learn more about our custom engineered products.
