This bearing housing carries a linear ball bearing insert mounted in a closed housing, designed for guiding loads along a shaft with rolling motion. Overall width is 88.0 mm, height 66.5 mm, and net mass 0.9 kg. The unit is sealed on both sides and supplied greased, with a relubrication facility built into the housing for topping up grease during service. The sealed design keeps out dirt and moisture, extending the interval between maintenance actions, while the relubrication port allows grease to be added without dismantling the housing from the shaft. The construction can also be produced in a corrosion-resistant version, suiting installations where the shaft or housing surface would otherwise be exposed to aggressive environmental conditions.
