This bearing housing carries a self-aligning linear ball bearing in an open design, allowing the unit to compensate for shaft misalignment during linear motion. Width is 43.0 mm, height is 28.0 mm, and net mass is 0.19 kg. Contact seals are fitted on both sides of the housing. The self-aligning ball bearing inside compensates for angular deviation between the shaft and housing bore, reducing sensitivity to mounting inaccuracies. The open design allows access for lubrication or maintenance, while the double-sided contact seals protect the linear ball bearing from dust and other contaminants along the shaft path, keeping the raceway free of debris during operation.
