Description

This plain bearing accommodates radial loads while allowing angular misalignment through a steel/steel sliding contact between the inner and outer ring. It is manufactured to DIN ISO 12240-1, dimension series E, with radial internal clearance CN (Group N). The unit weighs 0.138 kg and is fitted with 2RS sealing on both sides. The steel/steel sliding surface supports high load ratings, and the CN clearance class provides the fit needed for standard mounting conditions without excessive play. As a maintenance-requiring design, the bearing depends on periodic relubrication to sustain the sliding contact, while the 2RS seals limit contaminant ingress and help retain lubricant at the sliding interface. The spherical design compensates for shaft misalignment at the mounting point.
