New HFS radial shaft seals from SKF

SKF HFS seals

Easy-to-fit heavy-duty seals protect large bearings from contamination in demanding applications

SKF’s new heavy-duty HFS radial shaft seals protect large bearings from contamination in applications such as heavy-duty gearboxes and drives, construction machinery, and mining equipment.

Aimed at maintenance, repair, and operations (MRO) staff, the fabric-reinforced rubber seals are easy to retrofit and are typically available as stock products, which makes for more efficient maintenance.

Popular seal sizes are available as stock items, meaning that replacement parts can be delivered very quickly. HFS seals can easily be interchanged with other commonly used rubber fabric seals on the market. In addition to stock sizes, customized dimensions are available.

The seals also offer several sustainability benefits for customers. For instance, they help protect against loss of lubricant, while also saving resources by replacing large metal labyrinths. The extra protection helps to extend bearing life – and promotes the use of remanufacturing.

The main sealing lip of HFS seals has a garter spring that provides the appropriate radial load against the shaft. All HFS seals can be equipped with lubrication grooves, which allow re-greasing between the sealing lips in back-to-back or tandem installations of two seals.

As well as being made to SKF’s exacting standards, backed by test rig screenings, the seals have 100% traceability and SKF engineering support is widely available.
