This bearing housing combines a self-aligning linear ball bearing with an open slotted housing design, allowing compensation for shaft misalignment during linear motion. The unit measures 75.0 mm in width and 72.0 mm in height, with a net mass of 0.8 kg. It is sealed and pre-greased, with a relubrication facility built into the housing for maintenance access. The self-aligning ball bearing design allows the unit to accommodate slight deviations in shaft alignment, reducing sensitivity to installation inaccuracies. The sealing protects the internal raceway and balls from contamination, while the grease fill provides lubrication from the start; the relubrication facility permits replenishing grease over the service life without full disassembly. The open slotted housing construction suits mounting arrangements where a continuous shaft support is not required along the full length of travel.
