This unit supports a shaft through a radial insert ball bearing fixed in the housing with grub screws in the inner ring, giving a locking method that resists axial displacement on the shaft without additional fasteners. The cast iron housing (PASEY25-XL-N) has a bore diameter of 25.0 mm, width of 27.0 mm and height of 70.0 mm, with a net mass of 0.67 kg. The basic dynamic load rating is 14900.0 N. P seals are fitted on both sides of the bearing to keep the grub screw fixing enclosed. The grub screw fixing allows mounting directly on a shaft without an adapter sleeve, suiting applications where the shaft can be drilled or where the set screws can be tightened onto a plain shaft section. The cast iron housing body (bearing housing) gives a rigid mounting base at the stated height of 70.0 mm, while the P seal arrangement protects the inner bearing against contamination from the surrounding environment. The dimensional and constructional equivalent is HFB UCP205.
