This unit combines a plain bearing with a housing in an open design, sealed on all sides, width 84.0 mm, height 63.5 mm, net mass 0.43 kg. The housing carries a relubrication facility, allowing grease to be replenished without dismantling the assembly. The full-side sealing keeps contaminants away from the sliding surface while retaining grease inside the housing, which supports steady linear motion along a shaft. The open design of the housing simplifies mounting and shaft insertion, and the relubrication facility allows maintenance intervals to be planned without removing the unit from its mounting position.
