Peer SeedXTreme Bearing (for most gauge wheels, closing wheels and Needham firming wheels).



Key Benefits

The PEER® SEEDXTREME 5203 bearing is a direct replacement for standard 5203 bearings to  significantly extend their life.

  • Features 6 seals at each end, compared to most competitive bearings only having 2-3 seals at each end.
  • Fits most gauge wheels that use a 5/8” or 16 mm mounting bolt and all Needham Ag Gauge Wheels, Needham Ag closing wheels and the V8 Firming Wheels.
  • Inside diameter 0.64” (16.256 mm)
  • Outside diameter 1.574” (40 mm)
  • Width 1.737” (44.12 mm)


PEER´s Research and Development Center utilizes mud slurry testing to thoroughly study new bearing and seal concepts. Mud slurry testing involves immersing bearings in an abrasive liquid and counting the number of hours before they fail under a consistent load. Most bearings within the agricultural environment break down because the seals deteriorate, which allows contaminants to enter the bearing and dry the lubricants, rather than bearings failing directly.

Mud slurry tests are performed to compare the life of different brands of bearings within the same environment. The bar chart above compares the life of three different brands of 5203 bearing at 500 rpm in the mud slurry tank. The one on the right is the PEER® SEEDXTREME, which lasted more than three times longer than one major 5203 bearing manufacturer and over 7 times longer than a 2nd major 5203 bearing manufacturer.
