SKF · Bearings & Power Transmission · Pillow Block Ball Bearing Units
SKF SYJ504 pillow block ball bearing unit (ucp / uep / ukp). Two-bolt pillow-block cast-iron, SG-iron or thermoplastic housing pre-assembled with a spherical-outer-ring insert bearing. Absorbs shaft-to-support misalignment during assembly and in service. Standard shaft attachment is set-screw (UCP); eccentric locking collar (UEP) and adapter-sleeve (UKP) variants available. Dimensioned to ISO 3228 / DIN 626. Designation follows the SKF alphanumeric identification convention where the numeric block encodes the boundary plan and the suffix declares execution options.
