Examples |
Typical Part Number |
TB2-021002800070-NCC |
This is profile TB2 for a 21.0 mm shaft, 28.0 mm bore and 7.0 mm width with 0.0. sealant, nitrile primary sealing lip, carbon steel case and carbon steel spring. |
|
SA2-035006500120GPSS |
This is profile SA2 for a 35.0 mm shaft, 65.0 mm bore, and 12.0 mm width with a ground O.D., polyacrylate primary sealing lip, stainless steel case, and stainless steel spring. |
|
HSCJR-080011 0001 OO-XCS |
An "H" is placed in front of the profile designation when a hydrodynamic aid is to be molded into the lip. The design of the hydrodynamic aid (Hydrodynamic Aids, page 580) immediately follows the profile designation.
This is profile SCJ with type "R" hydrodynamic aid for a 80.0 mm shaft, 110.0 mm bore, and 10.0 mm width. The seal has a carboxylated nitrile primary sealing lip, carbon steel case, and stainless steel spring. |

Radial shaft seals are manufactured in a large range of sizes and styles. To expedite the ordering process a straightforward part numbering system has been developed. Following is a detailed description of this system.
The part number is composed of the seal profile, shaft diameter, bore diameter, width of seal, O.D. treatment (O.D.T), lip material, case material and spring material. Below is a representation of how the part number is assembled. |
|
Profile shaft bore width O.D. T lip case spring
• Profile: Selected from Profile Matrix (page 48D) e.g. TB2, UB2
• Shaft: The diameter of shaft where the seal will operate
• Bore: The diameter of bore where the seal will operate
• Width: The width of the seal case
• O.D.T: Outside Diameter Treatment
- : O.D. sealant (standard)
G : Ground O.D.
(Sealant and Ground only an option on metal O.D. radial shaft seals)
- Lip: Material (page 33C) of primary sealing element
N : Nitrile
T : Polytetrafluoroethylene (Teflon) F : Fluorocarbon (Viton)
P : Polyacrylate
S : Silicone
E : Ethylene Propylene (EPOM)
H : High Temperature Nitrile
X : Carboxylated Nitrile
- Case: Case material
C : Carbon steel (1008-1010)
S : Stainless steel (30304)
- Spring: Spring material
C : Carbon steel (1070-1090)
S : Stainless steel (30304)
