• 8000 & 8700 Felt Seal Series Bearings - PDF / HTML
  This light duty series of single row radial ball bearings have felt seals. The inner ring is extended on the seal side of the bearing to provide a smooth land for the felt seal to contact. Of the two metal stampings enclosing the seal, the outer one fits into the groove to form a close clearance ultimately increasing the effectiveness of the seal.
  
• WC8000 & WC8700 Felt Seal Series - PDF / HTML
  This is a wide cup single row radial ball bearing series with high quality felt seals. They keep the initial performance constantly even at a continuous high-speed operation.
  The light touch of the wider outer ring with the housing reduces the torsion and wearing of the housing. It is designed to have a good fit to the housing, which is made of relatively soft metals such as aluminum.
  
• 8800 Felt Seals Series - PDF / HTML
  These felt seal series bearings have the same dimensions as Type 8000 and Type 87000 except for the width of the inner ring. The adequate and tough land for the two pieces of felt seals to contact helps the precision ground raceways and steel balls, which are filled with completely filtered grease.
