Y-bearings for agricultural applications

Y-bearings for agricultural applications are designed to withstand the demanding operating conditions that occur in machinery like combines and balers, harvesters and disk harrows. Extensive laboratory tests and field experience confirm that these bearings outlast conventional bearings, which typically have a one to three year life span.
Y-bearings for agricultural applications are equipped with a patented 5-lip seal on both sides. The bearings are lubricated for life with VT307 grease (table 1). The grease has a high resistance to water washout, enabling long bearing service life in wet environments. The bearings cannot be relubricated.
Y-bearings for agricultural applications are dimensionally interchangeable with standard Y-bearings, enabling easy upgrades of existing applications to reduce machine downtime and environmental impact. SKF Y-bearings for agricultural applications are available for metric shafts from 20 to 50 mm and for inch shafts from 1 to 1 15/16 inches. The bearings are available with three different locking methods:
  • Y-bearings in the YARAG 2 series (fig. 1), which are interchangeable with bearings in the YAR 2 series, are locked onto the shaft with two grub screws. They are typically used for moderate loads.
  • Y-bearings in the YELAG 2 series (fig. 2), which are interchangeable with bearings in the YEL 2 series, are locked onto the shaft by an eccentric locking collar. The eccentric collar is black oxidized. The bearings are typically used for moderate loads.
  • Y-bearings in the YSPAG 2 series (fig. 3), which are interchangeable with bearings in the YSP 2 series, are locked onto the shaft by the patented SKF ConCentra locking technology. This locking technology enables the bearing to accommodate heavier loads than other locking methods.
Other Y-bearings for agricultural applications are available on request:
  • bearings with zinc-coated rings
  • bearings with a cylindrical outer ring
  • bearings with other locking methods
