Oil Seals SA/TA
SA and TA oil seals are available with a visible outer metal casing (SA) or fully covered with elastomer (TA), and are designed for applications with specific installation requirements or corrosion resistance needs. The SA model has an exposed metal housing, whilst the TA offers additional protection against corrosion and a more effective seal thanks to its full elastomer coating. Both types are frequently used in transmissions, machinery, pumps and other mechanical equipment. Hydraulic Seals Store offers SA and TA seals made from NBR and FKM, available from stock with fast delivery in Romania.
What are SA-TA oil seals and for which systems are they suitable?
SA and TA seals are recommended for applications where the mounting surface may be corroded or uneven. See also pressure seals and SB-TB seals for other types of specially designed seals.
The role of SA-TA oil seals
The sealing lip of SA and TA seals functions in the same way as the standard A model, ensuring a tight seal on the shaft. The main difference lies in the housing design: the SA has an exposed metal housing, suitable for bores in good condition, whilst the TA has an elastomer-coated housing, providing additional external sealing and making it suitable for corroded bores or those with wide tolerances.
Common areas of application for SA-TA oil seals
Transmissions, machinery, pumps and mechanical equipment
SA-TA seals are found in automotive and machinery transmissions, water pumps, industrial gearboxes, electric motors and other mechanical equipment with rotating shafts. See also V-type seals for additional protection.

Frequently Asked Questions
What are SA oil seals most commonly used for?
SA oil seals are frequently used in transmissions, pumps, gearboxes and motors, in applications where the mounting surface is in good condition and shows no signs of corrosion or wide tolerances.
What are the design features of SA and TA oil seals?
The SA oil seal has a visible outer metal casing, whilst the TA has a casing completely covered with elastomer. This gives the TA oil seal an additional seal against the housing and better resistance to corrosion.
How do you choose between an SA and a TA oil seal?
Choose the TA when the housing shows signs of corrosion, wear or wide tolerances, as the elastomer-coated casing compensates for irregularities. The SA is suitable for housings in good condition with tight tolerances.
Under what operating conditions are TA oil seals recommended?
TA seals are recommended in environments where there is a risk of corrosion, in applications with worn housing, or in situations where a better seal between the seal and the housing is required.
