This bearing housing combines a linear ball bearing with a housing unit for guidance along a shaft, sealed on both sides and pre-greased for immediate installation. The unit measures 43.0 mm in width and 36.5 mm in height, with a net mass of 0.16 kg. The design allows for corrosion-resistant execution where required. Sealing on both sides keeps grease in and contamination out during operation, while the relubrication facility allows grease to be replenished without dismantling the housing from the shaft. This combination of sealing and relubrication supports continuous linear motion applications where consistent lubrication over the service life is required without frequent disassembly.
