SKF P4B311-SRB-CRH — Roller-bearing pillow-block unit
SKF · Bearings & Power Transmission · Pillow Block Roller Bearing Units
SKF P4B311-SRB-CRH roller-bearing pillow-block unit. Cast-iron pillow-block housing pre-assembled with a spherical roller bearing on adapter sleeve. Two-bolt (SYNT / FYNT / SBP) or four-bolt (SFT / FSNL) execution. Suitable for heavier shaft loads than ball-bearing pillow-block units on marine deck cranes, conveyors and process machinery. Designation follows the SKF alphanumeric identification convention where the numeric block encodes the boundary plan and the suffix declares execution options (material, sealing, cage, precision, clearance, lubricant). Genuine SKF supply carries the SKF logo etch or moulded mark and hologram-authenticated packaging.
