Provides linear guidance for a shaft by combining a ball bushing with an integrated housing, allowing direct mounting without a separate pillow block. The unit measures 47.0 mm in width and 48.5 mm in height, with a net mass of 0.303 kg, giving a compact bearing housing suitable for direct fitting onto a support structure. The design is sealed on both sides, which keeps the recirculating balls protected from dust and moisture while retaining the applied grease inside the unit. Because the housing and ball bushing form one preassembled component, alignment work during installation is reduced, and a corrosion-resistant version of this bearing housing (KGHA20-PP) is available for environments where standard steel parts would be exposed to increased moisture or aggressive media.
