SKF HMSA10V Radial Shaft Seal

SKF 125X150X12 HMSA10 V is a rubber‑metal reinforced radial shaft seal designed to seal a 125 mm shaft inside a 150 mm housing bore with a 12 mm cross‑section. The “V” suffix denotes a Viton (FKM) sealing lip, delivering enhanced resistance to oils and high temperatures compared with standard elastomers. This seal combines metal reinforcement with a Viton lip and a rubber exterior, providing robust performance in demanding service. Typical applications include pumps, gearboxes, and hydraulic motors where a durable lip seal on rotating shafts is required; the Viton lip enhances chemical compatibility and heat resistance in oil and fuel environments. SKF’s industrial seals catalog confirms HMSA10 V as part of the HMSA/HMS5 family designed for general industrial applications and provides the precise id/od/width dimensions of 125 mm / 150 mm / 12 mm for this model.
