This bearing housing integrates a linear ball bearing with its mounting body, symbol KTB16-B-PP-AS, width 53.0 mm, height 42.0 mm, net mass 0.45 kg. The unit is sealed and greased, fitted with a relubrication facility, and available in a corrosion-resistant design. The seals retain grease at the raceway and keep out contaminants, so no separate protection is required around the shaft. The relubrication facility lets grease be replenished during operation without removing the housing from its mounting. The corrosion-resistant version is suited to conditions where the shaft and housing surfaces are exposed to moisture, while the 53.0 x 42.0 mm envelope keeps the mounting footprint small.
