Challenge UCPX15-48 MP3 Triple Sealed Medium Duty Pillow Block

Challenge housed bearings are available in the following configurations: normal duty pillow blocks (UCP2.); medium duty pillow blocks (UCPX.); 2-hole flange units (UCFL2.); normal duty 4-hole flange units (UCF2.); medium duty 4-hole flange units (UCFX.); flange cartridge units (UCFC2.); and take-up units (UCT2.). Choice is very much determined by the requirements of the application, although aesthetic appearance of the machine design is often an important consideration. Challenge bearing units have been designed to meet the needs of both criteria. The castings are made of high quality cast iron, and fitted with a standard re-grease able bearing insert. The housings are provided with a tapped hole to facilitate re-lubrication and supplied with a grease nipple. Challenge bearing inserts are available in either normal duty (UC2.) or medium duty (UCX.). The Challenge triple lip seal consists of a one-piece moulded nitrile seal with three sealing lips, bonded to a protective steel outer pressing which is strongly secured in the outer ring making a highly efficient mounting arrangement. Challenge bearings are factory charged with the correct amount of grease and do not require a further grease charge when being fitted. Re-lubrication is not normally necessary except when operating at extremes of temperature, speed, loading extended running, or where excessive wet or dirty conditions exist. The shaft locking arrangement consists of two knurled cup-point, self-locking, socket-head set screws fitted in the extended inner ring. For normal loads and moderate speeds simply mount the bearing unit into position and tighten down the set screws to the recommended torque value. Challenge bearing units accommodate initial housing misalignment up to 0,030 radians but are not recommended for running misalignment in excess of 0,001 radians.
