Oil Seal TA - Rotary Shaft Seal
TA oil seals are radial shaft seals featuring a full metal outer diameter and reinforced metal cap, engineered to ensure stable, high‑precision fitting within rigid metal housings. The sealing lip is available in NBR, FKM, ACM, EPDM, HNBR, and VMQ materials, selected according to application requirements such as operating temperature, chemical resistance, and compatibility with lubricants. Thanks to its metal outer structure, spring‑loaded main lip, and auxiliary dust lip, the TA series delivers consistent and dependable oil sealing performance, even under fluctuating shaft speeds, varying temperatures, and light contamination conditions. The integrated dust lip helps maintain cleanliness in the primary sealing area against dust, moisture, and fine particles, significantly improving durability and prolonging both seal and equipment service life.
This seal type is also referenced under alternative designations including WCS, OS‑C11, TR‑F, CRWHA1, CS, GVST, L2P, B2 SL, 824 S, DFSK, DC, 41, CSEL, and KCS.
FAQ
What is a TA rotary shaft seal?
TA rotary shaft seals are radial shaft seals with a full metal outer diameter and reinforced metal cap. They are designed for stable, precise fitting in rigid metal housings and provide reliable oil sealing for rotating shafts.
What is the working principle of a TA oil seal?
A TA oil seal uses a spring-loaded main sealing lip to maintain close contact with the rotating shaft, preventing oil leakage. An additional dust lip blocks dust, moisture and particles to protect the main sealing area.
What materials are available for TA oil seals?
TA oil seal lips can be made from NBR, FKM, ACM, EPDM, HNBR and VMQ. The material is selected according to temperature range, chemical exposure and lubricant type.
What are the key benefits of TA type oil seals?
TA oil seals offer stable sealing performance under speed changes, temperature fluctuations and mild contamination. The metal outer diameter ensures dimensional stability, while the dust lip improves durability and service life.
Where are TA rotary shaft seals typically applied?
They are widely used in motors, gearboxes, pumps, agricultural machinery, construction equipment and automotive systems that require reliable sealing in harsh working conditions.
How does the dust lip improve TA oil seal performance?
The dust lip prevents dust, dirt and moisture from entering the main sealing zone, reducing wear and avoiding premature failure. This helps extend both seal life and overall system service life.
What other designations are equivalent to TA oil seals?
TA oil seals are also known as WCS, OS-C11, TR-F, CRWHA1, CS, GVST, L2P, B2 SL, 824 S, DFSK, DC, 41, CSEL and KCS in different brand standards.
How to install a TA rotary shaft seal correctly?
TA oil seals should be installed into rigid metal housings with even pressure to avoid deformation. The sealing lip must face the fluid side, and the shaft surface should be smooth and free of burrs to ensure proper sealing.
