SF series AISI440C Flanged Bearing Units

SMT’s SF series are high-precision flanged bearing units made with single low deep groove stainless steel bearing and stainless bearing housing, that can be fixed directly to machines and equipments easily with four bolts. SMT bearing units can contribute significantly to cost reduction by simplified facility design and improved work efficiency.

Features

  1. Both bearing and housing made of AISI440C stainless steel are superior for corrosion resistance and clean environment, therefore suitable for use in food machinery, equipment in clean room, chemical processing machine, cleaning equipment, and equipment that should look beautiful.
  2. Aligning function can reduce the stress on the bearing by the error of shaft center and the flexure of the shaft.(SSA and SSXCA types)

  3. The adequate fit is kept between the bearing and the housing because no difference occurs in the amount of expansion and contraction by using AISI440C stainless steel for both components.
  4. Best used for the applications that require precise positioning by the precision finishing. As for SSXCA and SSXC types, shaft can be easily fastened with set screws.
