This bearing housing carries a self-aligning linear ball bearing in an open design, mounted inside a compact housing measuring 75.0 mm in width and 72.0 mm in height, with a net mass of 0.7 kg. The basic static load capacity is rated at 4300.0 N. The unit is sealed and greased, with a relubrication facility allowing fresh grease to be added during service. The self-aligning feature of the linear ball bearing compensates for slight shaft misalignment, keeping the assembly running smoothly even when the shaft is not perfectly straight. The sealed design keeps contaminants out while retaining the grease fill, and the relubrication facility supports periodic grease replenishment without dismantling the housing, which simplifies maintenance intervals on linear motion shafts.
