| |
Type C
 |
The C Structure denotes a rubber-covered case. This design helps prevent rusting and corrosion of the metal case. It also helps prevent damage to the housing bore during assembly and compensates for thermal expansion. The C structure is recommended for, but not limited to aluminum housings. |
| |
Type B
 |
The B structure denotes metal on the O.D. with a rubber lining covering the internal face of the steel case. Outside diameters can be plain metal, (with a coating treatment to prevent rust), ground (for more exact tolerances) or painted (to provide an improved seal in the bore). These types of structures are usually used for sealing when the shaft diameters are under 6 inches and for applications with possible corrosion problems. |
| |
Type B2
 |
The B2 structure denotes metal on the O.D. of the seal. Outside diameters can be plain metal, (with a coating treatment to prevent rust), ground (for more exact tolerances) or painted (to provide an improved seal in the bore). These types of structures are usually used for sealing when the shaft diameters are under 6 inches and for steel or cast iron housing materials. |
| |
Type BR
 |
The BR structure denotes metal on the O.D. with a rubber lining covering the internal and top face of the steel case. Outside diameters can be plain metal, (with a coating treatment to prevent rust), ground (for more exact tolerances) or painted (to provide an improved seal in the bore). These types of structures are usually used for sealing when the shaft diameters are less than 6 inches and allow for improved O.D. sealing ability. |
| |
Type A2
 |
The A2 structure denotes seals that are reinforced with a second metal case. This type structure is very effective in applications where the shaft diameter is greater than 6 inches. This design can also be used on smaller shafts that need extra strength, or when special compounds are required. |
| |
W Series
 |
The W series is used in applications subject to wide variances in thermal expansion or for press fitting into a housing where installation is difficult. |
| |
Agricultural designs
 |
The agricultural designs are multi-lipped pre-lubed seals used in conjunction with wear sleeves to prevent dirt from entering the system. |
| |
Type E
 |
This series is to be used for large shaft to bore misalignment or excessive dynamic run-out. |
| |
Type O
 |
The O design is for applications where the bore turns and the shaft is stationary. |
| |
Pressure Series
 |
The pressure seals are used in applications where pressure may range up to 100 PSI. |
| |
Type 3
 |
The Type 3 design has a grease cavity and will allow for pre-lubrucation of the seal. The secondary lip will also allow for dirt exclusion. |
| |
Type 4
 |
The Type 4 design is used for linear applications. |
| |
Type 5
 |
The Type 5 design is designed for applications where additional rigidity is needed and restricts the installation depth into the housing. |
| |
Type 6
 |
The Type 6 design adds ease of installation and restricts the depth of installation. |
| |
Type 7/9
 |
The type 7/9 design is used in heavy-duty applications where dirt exclusion and outside sealing is required. |
| |
Flange Design
 |
The Flange design allows for easy installation or replacement. It adds rididity and restricts installation. |
| |
Type Y
 |
The Type Y design is used for applications where the seal lip and spring need to extend beyond the case. |
| |
End Covers Design
 |
The End Cover design protects bearings from contaminants. |
| |
Wiper Series
 |
The wiper series is used primarily in reciprocating applications as a dirt excluder. Our most popular wiper is the WPB style. The WPB series is normally produced with a ground O.D. and 90-durometer nitrile material. |
