igubal® 4-Hole Flange Bearing EFSM 2.0

The igubal® EFSM 2.0 is the second-generation 4-hole flange bearing for supporting shaft ends or shaft bushings in a compact mounted housing. Like the first-generation EFSM, it uses an igumid G housing in dimensional series E following DIN ISO 12240 and is built for maintenance-free dry operation, corrosion resistance, low weight, and compensation of misalignment.

What makes the 2.0 version different is the housing redesign. igus says the housing was optimized for a fully seated mounting surface, reduced dirt ingress, and more efficient material use. The nature-inspired geometry lowers weight without sacrificing static performance, while the optimized stress distribution helps reduce stress peaks and maintain the performance level of the previous EFSM design.

The housing material remains impact-resistant igumid G and is rated for long-term temperatures from -40°C to +120°C, with short-term resistance up to +180°C. Standard spherical ball material is iglide® W300, with iglide® J and iglide® J4 also available, giving the bearing flexibility for different wear and motion requirements.
