BAB1SL / BABSL Seal Characteristic

• The BAB1SL style is a variation of high-pressure rotary seals, including a primary sealing lip and often a dust lip to guard against external contamination.

• These types are designed to operate under pressure without the need for back-up rings, with typical allowable pressures up to about 10 bar, depending on geometry and materials 

• FPM offers improved thermal and chemical resistance compared to NBR, enabling operation at higher temperatures and in more aggressive environments.

• Proper installation requirements (shaft finish, tolerances, surface quality, housing bore) must follow manufacturer guidelines to maintain sealing integrity.

• Suitable for use in hydraulic pumps, motors, gearboxes, mobile machinery, industrial equipment, and more.
