We can manufacture a wide array of needle bearings in different sizes. Please consult this list for more information:

 

  • Radial Roller Cage Bearings: Inner diameter (3 to 50 millimeters); outer diameter (5 to 100 millimeters); width (4 to 100 millimeters)
  • Drawn Cup Needle Roller Bearings: Inner diameter (3 to 50 millimeters); outer diameter (5 to 60 millimeters); width (4 to 30 millimeters)
  • Thrust Roller Bearings: Inner diameter (3 to 150 millimeters); outer diameter (5 to 175 millimeters); height (1.5 to 6 millimeters) 
  • Custom Needle Roller Bearings: Inner diameter (3.5 millimeters); outer diameter (5 to 100 millimeters); width (4 to 100 millimeters)

 

We customize each needle roller bearing based on your unique needs. The materials that we use will vary depending on the type of needle bearing you are requesting:

 

  • Radial Roller Cage Bearings: The retainer can be made from nylon, glass-filled nylon, or metal.
  • Drawn Cup Needle Roller Bearings: Our standard cup material is AISI 1012 carbon steel. We are happy to review any materials you would like to use for your custom bearing. Please note that the cup is case hardened and tempered to a 58 minimum HRC.
  • Thrust Roller Bearings: Universal Bearings uses SAE/AISI 1010 (low-carbon alloy) which is then heat treated to a minimum 58 HRC per SAE J86. We are happy to review other materials upon request. Our team can also manufacture lower cost plastic cages (nylon 6/6) for certain applications.
  • Custom Needle Bearings: We always use SAE 52100 bearing steel, but are happy to review other requested materials.

Currently, Universal Bearings is still being challenged by COVID-related labor shortages, transportation delays, and MRO supply delays. Because of these difficulties, our lead time is 12 weeks. Of course, the lead time will vary depending on the scope of the job. High-volume orders will take more time. We also keep an archive of bearing designs—if you use one of our designs, that may reduce the lead time. If reverse engineering is required for your custom order, that will also add onto the lead time.

When you place a purchase order with us, a team representative will provide you with a more accurate estimate.

Universal Bearings uses high-quality CNC lathes and grinders to create precision shafts and pins up to 35 millimeters in diameter, as well as needle bearing rings and races for rocker arms, hydraulic lifters, and more. If you have a design in mind, please contact us today, and we’ll let you know how we can help you.
