• are suitable for applications for both constant and alternating directions of rotation
• are locked onto the shaft by tightening the two cup point hexagonal grub (set) screws, positioned 120° apart in the inner ring

Basic design bearings

• are available with an inner ring extended on one side, bearing series YAT 2
• are available with an inner ring extended on both sides, bearing series YAR 2
• are capped on both sides with:
  • a rugged standard seal for bearing series YAT 2
  • a rugged standard seal and an additional plain sheet steel flinger, designation suffix 2F or a rubberized sheet steel flinger, designation suffix 2RF for bearing series YAR 2
• have two lubrication holes in the outer ring as standard, one on each side, positioned 120° apart
• can be supplied without lubrication holes on request (designation suffix W)

For demanding operating conditions that occur in agricultural applications, such as combines and balers, harvesters and disk harrows, SKF has designed the YARAG 2 bearing series. These bearings:

• are fitted with a patented 5-lip seal
  
• are supplied without any lubrication holes in the outer ring

Bearings with zinc-coated rings

• are intended for use in corrosive environments
• are available with an inner ring extended on both sides (bearing series YAR 2..-2RF/VE495)
• have grub screws made of stainless steel
• are capped on both sides with a highly effective multiple seal made of food-compatible rubber with a stainless steel insert and a stainless steel flinger
• are filled with a food-grade grease
• have two lubrication holes in the outer ring, one on each side, positioned 120° apart

Stainless steel bearings

• are intended for use in corrosive environments
• are available with an inner ring extended on both sides (bearing series YAR 2..-2RF/HV)
• have all steel components made of stainless steel, including rings, balls, sheet metal parts of both seals and flingers, and grub screws
• are capped on both sides with a highly effective multiple seal made of food-compatible rubber with a stainless steel insert and a stainless steel flinger
• are filled with a food-grade grease
• have an annular groove with one lubrication hole in the outer ring, located on the side opposite the locking device
• have a lower dynamic load carrying capacity than same-sized bearings made of high grade carbon chromium steel
