SBF Series 4 Bolt Flange Mounted Bearing Units

SBF Series 4 Bolt Flange Mounted Bearing Units
ISUTAMI SBF 4-bolt mounted bearing unit, also known as SBF 4-bolt square flanged housing with bearing. It is usually used when the bearing mounting surface is perpendicular to the shaft. The flanged housing is integrally formed and the main material is cast iron. The surface of the cast iron is painted, galvanized or nickel plated for corrosion protection. It has four bolt holes distributed near four corners to fix the entire product. The inner ring of the bearing housing is spherical and combined with the outer spherical ball bearing of the corresponding size to form a complete bearing unit. The insert spherical bearing is suitably mounted on the inner ring of the matching bearing case. In order to prevent dust, the bearing is usually equipped with a rubber ring on both sides. The 4-bolt bearing housing has a square appearance and the total unit can withstand higher loads than 2-bolt flange mounted bearing unit. Compared with ISUTAMI 2-bolt flange mounted bearing unit and 3-bolt flange mounted bearing unit, it is better suited for long shaft mounting. The dimensions of the inner ring and housing in the bearing unit are divided into inch and metric.

SBF series bearing unit, is a product with metric bolt holes. It is light duty, with a narrow inner ring, the inner ring protruding part with set screw locking for fixing the shaft. The bore diameter ranges from 1/2" to 1-9/16". SBF 4-bolt housing unit with bearing is usually fixed directly to the equipment through four bolt fixing holes on the flange for easy installation. If the product needs to be replaced, you can remove the fixing screw and replace it with a new one.

The bearings on SBF unit can be maintained by re-lubricating.The performance of a bearing is greatly influenced by the quality and quantity of the grease. In order to avoid over filling, it is advisable to replenish the grease in small amounts. Over lubrication is a major cause of bearing failure. Over filling can increase heat build-up in the bearing during operation which can lead to premature failure. Over filling can also dislodge seals and flingers from their mounting position thereby interfering with the rotation of the bearing or destroying the integrity of the seal.
