• are suitable for applications for both constant and alternating directions of rotation
• provide an easy, quick and reliable way to lock a bearing onto a shaft, even in applications where there are heavy loads and/or high speeds
• permit the full limiting speed to be achieved, even where using commercial grade shafts
• have an inner ring symmetrically extended on both sides (bearing series YSP 2)
• comprise the patented SKF ConCentra locking technology, which is based on the expansion and contraction of the following two mating surfaces, which have precision-engineered serrations:
  • the bearing bore
  • the external surface of the stepped sleeve
• provide a true concentric fit on the shaft, because when the grub screws in the mounting collar are tightened, the inner ring is axially displaced relative to the stepped sleeve, forcing the bearing inner ring to expand and the stepped sleeve to contract evenly
• provide low noise and vibration levels, and virtually eliminate fretting corrosion
• are capped on both sides with a rugged standard seal and an additional plain sheet steel flinger
  
• 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 YSPAG 2 bearing series. These bearings:

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