SKF OR123.42X3.53-N70 — O-ring / back-up ring
SKF · Seals & Gaskets · O-Rings & Back-up Rings
SKF OR123.42X3.53-N70 o-ring / back-up ring. SKF O-ring in nitrile (NBR), hydrogenated nitrile (HNBR), fluoroelastomer (FKM / Viton), ethylene-propylene (EPDM) or silicone (VMQ). Dimensioned to AS 568A imperial, ISO 3601 metric, or JIS B 2401. Companion PTFE / thermoplastic back-up rings extend service pressure to 700 bar in dynamic hydraulic applications by preventing extrusion into the sealing gap. 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.
