§  Assembly Options Include:

§  Press Fit

§  Crimped (Swaged)

§  Welded End Plates (Bosses) with internal bearings

§  Fully Welded Tube & Axles

 

Axles

  • Sizes range from 1/4” to 3 7/16”
  • Shapes include Hex, Round, or Square
  • Materials include Mild Steel and Stainless Steel
  • Axle Retentions include:

§  Spring

Bearings

§  Non-Precision

§  A full ball complement in a stamped metal body

§  Zinc plated for better corrosion resistance

§  Recommended for light loads and slow speeds

§  Not intended for quiet operation

§  Very cost effective

 

§  Semi-Precision

§  Made of machined steel with tighter tolerances than non-precision bearings

§  Includes a ball retainer to keep the balls separated and evenly spaced 

§  Capable of higher speeds and higher load capacities than non-precision bearings

§  Available in stainless steel

 

§  ABEC Precision

§  Made from high quality, heat treated steel and ground to a micro finish with tolerances much tighter than semi-precision bearings

§  Capable of even higher speeds and higher loads than semi-precision bearings

§  Sensitive to axle deflection which may limit load capacity in long rollers

§  Recommended for quiet operations

§  Many styles available including polypropylene housed, insert, agricultural, Framesavers, and more

 

§  Bushings

§  Solid pieces of material with no moving parts

§  Materials include UHMW, Hardwood, Teflon, Nylon and more 

§  Recommended for use in extreme temperatures, dirty environments, corrosive environments, or sanitary conditions depending on the material
