Bearing BS2-2218-2CS HFH

Product detailed description

The SKF BS2-2218-2CS is a spherical roller bearing engineered to accommodate heavy radial loads and axial forces in both directions. Its robust design ensures durability and reliability in demanding applications.

Key Features:

• Design: Features two rows of symmetrical rollers, a solid inner ring, and a concave spherical raceway in the outer ring, allowing for self-alignment and compensation of shaft deflections.

• Sealing: Equipped with sheet steel reinforced contact seals (2CS) made of acrylonitrile-butadiene rubber (NBR) on both sides, providing effective protection against contaminants and retaining lubricant.

• Lubrication: Contains an annular groove and three lubrication holes in the outer ring, covered with a polymer band, facilitating relubrication and extending bearing life.

• Lubricant: Pre-lubricated with extreme pressure bearing grease (SKF LGEP2) suitable for temperatures ranging from -20°C to 110°C, with a grease fill of 25% to 35%.
