ElastomersWith a variety of sealing compounds to select from, getting what you need for your application is easy with Durus.

Case MaterialsStandard seals are reinforced with AISI 1008-1010 carbon steel cases. The strong case offers protection against deformation and damage during installation.

TolerancesAll seals are manufactured in accordance to relevant standards. Shaft and bore sizes adhere to RMA or DIN standards for precise and effective fits.

Numbering SystemAn intelligent numbering system offers valuable information. Part numbers are in dimensional order making Durus seals easy to stock and locate.

Superior PackagingBecause Durus seals are individually bagged in durable, air-tight plastic, you can expect a longer shelf life than other packaging methods.

Lubricants and machinery may be very hot. Ensure that the system is cool before removing or replacing seals.

NomenclatureOil Seal Numbering SystemDurus part numbers are derived from the dimensions and features of the seal. All part numbers include some dimensional information as well as case, lip, and material designations.

Metric Seal Part NumbersMetric seal part numbers list the three seal dimensions, separated by two X's. The shaft diameter is listed first, followed by housing bore diameter. The width is listed last.

After the dimensions, a lip and case type is designated. The very end of the part number is reserved for a material code.

Inch-Dimension Seal Part NumbersThe numbering system employs a 5-digit number for seals with a shaft diameter of less than one inch and a 6-digit number for seals with a shaft diameter of one inch or larger.

For seals with a shaft diameter less than o
