This bearing housing combines a self-aligning linear ball bearing with a closed housing, allowing compensation for shaft misalignment during linear motion. The unit measures 53.0 mm in width and 42.0 mm in height, with a net mass of 0.19 kg. It is sealed on both sides and supplied greased, with a relubrication facility built into the housing for maintenance access. The self-aligning design of the linear ball bearing accommodates slight deviations in shaft straightness or housing alignment without binding, which reduces stress on the shaft during operation. The sealing keeps contaminants out of the rolling elements, and the relubrication facility supports periodic grease replenishment without disassembly, extending service intervals between maintenance actions.
