SKF offers the capability to manufacture customized machined seals practically “on demand” to meet exact specifications required by OEM or maintenance-related applications. SKF can supply virtually any type of rotating, reciprocating, or static seal, drawing from its catalog of several hundred standard profiles, and further can engineer unique sealing solutions tailored to particular application requirements.
Seals can be made from a wide variety of stock materials (rubber elastomers, polyurethanes, and thermoplastics, among others) or from specialty materials, such as SKF ECOPUR, a thermoplastic polyurethane exhibiting high abrasion resistance, low compression set, and excellent strength. Other options include materials complying with specific industry standards and regulations (such as FDA guidelines) and specially formulated proprietary materials.
Customized seal capabilities and quick turnaround are made possible by unique SKF SEAL JET technology. This CNC-controlled production system employs proprietary software and special cutting tools ideally developed for machining different polymers.
Continuous or molded one-piece seals can be machined up to 157 in. OD (outside diameter) and larger versions can be developed using a welding technique allowing on-site fitting and promoting ideal seal performance. Production quantities can range from a single piece to lots of several thousand delivered in less than five days for normal orders. Rush orders for seals up to 24 in. OD typically can be handled and shipped within a day.
