This bearing housing carries a linear ball bearing insert in an open design, allowing shafts to pass through without axial limitation. The unit is sealed on both sides and greased at the factory, with a relubrication facility for adding fresh grease during service. Width is 70.0 mm and net mass is 0.25 kg. A corrosion-resistant design is possible for this construction. The open design permits mounting on continuous shafting where the shaft extends beyond the housing on either side, suiting linear motion applications with straight-line travel. Factory grease fill combined with the relubrication facility means the unit can be re-greased in place without disassembly, supporting extended service intervals. The double-sided seals keep contaminants out of the ball track while retaining lubricant, which matters for maintaining smooth linear travel over the working life of the unit.
