2TS-IM assemblies are comprised of two single-row bearings with an inner and outer ring spacer. In some applications, a shoulder in the bearing housing replaces the outer ring spacer.

Design Attributes
  • Stainless steel ball bearing inserts with set screw
  • Steel spacers are used to create Bench End Play (BEP) or Preload (BPL) in the bearing assembly
  • Available with or without spacers
  • Spacers preset during manufacture
