Rotary Shaft Oil Seals
Available8,458 products
Rotary shaft seals sit between rotating and stationary parts on a shaft to retain oil. They consist of a metal case that fits into a bore housing and a sealing lip made of an elastomer or rubber material which presses against the surface of the shaft to create a seal. These seals include a garter spring that presses the sealing lip against the shaft for a tighter seal to retain oil. Rotary shaft oil seals are used in automotive engines, transmissions, and industrial machines that require the retention of oil in the housing of rotating parts.
Single-Lip Oil Seals with Metal Cases for Smooth Bores
These single-lip rotary shaft seals retain oil and have a metal case for fitting to a bore with a smooth finish. Their sealing lip presses against the shaft to prevent oil from leaking out during operation. Single-lip seals can operate at higher speeds than dual-lip seals.

Single-Lip Oil Seals with Reinforced Metal Cases for Smooth Bores
These single-lip rotary shaft seals retain oil and have a reinforced metal case for a strong, rigid fitting to a bore with a smooth finish. Their sealing lip presses against the shaft to prevent oil from leaking out during operation. Single-lip seals can operate at higher speeds than dual-lip seals.
Single-Lip Oil Seals with Rubber-Enclosed Cases for Rough Bores
These single-lip rotary shaft seals retain oil and have a rubber-enclosed metal case for fitting to a bore housing with a rough surface. The rubber conforms to the rough bore to ensure a tight fit. The sealing lip presses against the shaft to prevent oil from leaking out during operation. Single-lip seals can operate at higher speeds than dual-lip seals.
Dual-Lip Oil Seals with Metal Cases for Smooth Bores
These dual-lip rotary shaft seals retain oil and have a metal case for fitting to a bore with a smooth finish. These seals have an auxiliary lip, or dust lip, that protects the sealing lip from contaminants in harsh environments. Dual-lip seals reduce wear and extend the life of the seal but operate at lower speeds than single-lip seals.
Dual-Lip Oil Seals with Reinforced Metal Cases for Smooth Bores
These dual-lip rotary shaft seals retain oil and have a reinforced metal case for a strong, rigid fitting to a bore with a smooth finish. These seals have an auxiliary lip, or dust lip, that protects the sealing lip from contaminants in harsh environments. Dual-lip seals reduce wear and extend the life of the seal but operate at lower speeds than single-lip seals.
Dual-Lip Oil Seals with Rubber-Enclosed Cases for Rough Bores
These dual-lip rotary shaft seals retain oil and have a rubber-enclosed metal case for fitting to a bore housing with a rough surface. The rubber conforms to the rough bore to ensure a tight fit. These seals have an auxiliary lip, or dust lip, that protects the sealing lip from contaminants in harsher environments. Dual-lip seals reduce wear and extend the life of the seal but operate at lower speeds than single-lip seals.
