Wire Straightener Bearings & Wire Straightener Accessories

All Novo standard v-groove bearings are precision ground to 120° rather than the standard 90°angle.  The purpose is to apply a less drastic pressure angle, thereby minimizing deformation of the original material shape.
All Novo bearings are factory lubed for assembly.  440 stainless steel is available upon request in most sizes and run at the same speed as the standard shielded bearings.  Sealed bearings are available in most sizes.

FAQs

• What are wire straightener bearings?  

   

  Wire straightener bearings, also called straightening rolls, are precision components used in wire straightening equipment to control and remove variation in wire as it passes through the straightener. The accuracy, concentricity, and positioning of the bearings are critical to achieving consistent straightness and repeatable results.

• What makes Novo Precision wire straightener bearings different?  

   

  Novo Precision precision-grinds its standard V-groove bearings to a 120° angle rather than the more common 90° V-groove. The wider angle applies a less aggressive pressure angle to the wire, helping minimize deformation while maintaining precise control of the material.

• Why does the V-groove angle matter?  

  The V-groove geometry determines how the bearing contacts and applies pressure to the wire. A standard 90° V-groove can apply more squeezing force to the material, potentially deforming the wire. Novo Precision's 120° V-groove is designed to use a less drastic pressure angle, helping maintain the original shape of the wire.

• Can Novo Precision bearings replace bearings on other manufacturers' wire straighteners?  

  Yes. Novo Precision wire straightener bearings are available in standard sizes for Novo straighteners and can also be customized to fit many competitor's straightening equipment. To determine compatibility, provide the ID and OD of your existing straightener rolls.

• How do I determine which replacement wire straightener bearing I need?  

  The easiest way to identify the correct bearing is to provide the inside diameter (ID), outside diameter (OD), and width of your existing straightener roll. Novo Precision can use those dimensions to help determine the appropriate replacement bearing.

• What sizes of wire straightener bearings are available?  

  Novo Precision offers a range of standard bearing series, from small Series 00 bearings through larger Series 07 bearings. Standard outside diameters range from approximately 0.188 inches to 3.500 inches, depending on the bearing series. Custom sizing may also be available.

• Are Novo wire straightener bearings precision ground?  

  Yes. Precision grinding is an important part of Novo Precision's wire straightener bearing design. The bearings are manufactured to high tolerances to provide accurate and repeatable wire control.

• Why is bearing concentricity important in a wire straightener?  

   

  Bearing concentricity directly affects the ability of the straightener to control wire position. Even small variations in bearing geometry can affect the wire's direction and straightness. Novo Precision notes that a 0.001-inch adjustment to a bearing on its precision wire straighteners can change the direction of the wire, demonstrating how sensitive the system is to bearing accuracy.

• Are Novo wire straightener bearings lubricated?  

  Yes. Novo Precision standard bearings are factory lubricated for assembly.

• Are sealed wire straightener bearings available?  

  Yes. Sealed bearings are available in most sizes, providing an option for applications where sealed bearing construction is preferred.

• Are stainless steel wire straightener bearings available?  

   

  Yes. 440 stainless steel bearings are available upon request in most sizes. These bearings can operate at the same speeds as the standard shielded bearings.

• What is the maximum speed of Novo wire straightener bearings?  

  Maximum operating speed depends on the bearing series and size. Novo Precision offers bearings with rated speeds ranging from approximately 5,000 RPM to 109,000 RPM across its standard series. Actual operating conditions should be reviewed when selecting a bearing.

• Can I purchase replacement bearings for an existing Novo wire straightener?  

   

  Yes. Novo Precision supplies replacement wire straightener bearings and related components for its equipment. If you need replacement rolls, provide the model or bearing dimensions to help identify the correct components.

• Can I purchase bearings for a competitor's wire straightener?  

  Yes. Novo Precision can customize bearings to fit many competitor wire straighteners. Providing the ID and OD of your current straightener rolls is the best way to determine whether a replacement bearing can be manufactured.

• What information should I provide when requesting a quote?  

  For the fastest quote, provide:

  • Existing bearing ID
  • Existing bearing OD
  • Bearing width
  • Wire diameter
  • Wire material
  • Straightener manufacturer and model, if known
  • Quantity required
  • Preferred bearing material or construction
  • Any special application requirements

  A sample bearing or detailed drawing can also help with identification.

Wire Straightener Bearings:

Novo Precision Wire Straightener Bearings are placed closer in proximity to each other than any other wire straightener on

the market.  That is just one of the reasons why the Novo PWS's react to fine adjustments much more agressively than any other straightener.

Inferior bearings will create inferior control or lack of it.  The accuracy of the bearing is an integral part of the Novo PWS's advantage to remove variation in the wire and therefore, cannot be reproduced as other roll straighteners are manufactured.  On a Novo wire straightener, when you adjust one of the bearings just .001 of an inch, the wire will change its direction.  If any one or more of our 28 rolls were not produced from high quality bearings and the shape was not ground to a high tolerance of concentricity, the performance of these precision instruments would decline dramatically.
