Description

This plain bearing accommodates radial loads while allowing angular misalignment through a steel/steel sliding contact surface, in line with DIN ISO 12240-1, dimension series E. The GE90-DO-2RS carries a net mass of 2.682 kg and is fitted with 2RS sealing on both sides, protecting the sliding surface from contamination while retaining lubricant within the contact zone. Radial internal clearance corresponds to group CN (Group N), suitable for standard mounting conditions without additional preload. As a maintenance-requiring design, the bearing needs periodic relubrication to sustain the sliding contact performance and support high load ratings over its service life. The sealed construction makes it suitable for applications where ingress of dirt or moisture must be limited while still permitting angular adjustment at the bearing seat.
