This unit combines a plain bearing with a closed housing designed for linear motion applications. Symbol PAGBA30-PP-AS has a width of 84.0 mm, a height of 67.0 mm, and a net mass of 0.48 kg. The housing is sealed on all sides, protecting the bearing from dust and contaminants, and includes a relubrication facility for maintaining the lubrication film during operation. The full sealing on all sides makes this plain bearing suitable for use where protection against particle ingress is required along the linear travel path. The built-in relubrication facility allows fresh grease to be added without dismantling the unit, supporting consistent lubrication over the service life of the bearing. The closed housing design also simplifies alignment during mounting, as the bearing and housing are supplied as one assembled unit.
