Rotary Shaft Oil Seal | Double Lip | Shaft Diameter (28mm) x Bore Diameter (40mm) x Width (7mm) | Nitrile Rubber Lip Material.
Product Overview:
The Rotary Shaft Oil Seal (28mm x 40mm x 7mm) with a double lip profile is engineered to deliver exceptional sealing performance in rotating applications. Designed for use in medium-duty machinery, this seal combines a Nitrile Rubber (NBR) lip, metal casing, and an integrated garter spring to maintain continuous radial contact on the shaft.
The 7mm width allows installation in relatively compact housings, making this seal ideal for electric motors, pumps, gearboxes, and automotive systems where efficient oil retention and dust exclusion are essential.

❓ Frequently Asked Questions (FAQ)
Q: What is the function of the double lip design?
A: The double lip helps retain internal lubricants while blocking external contaminants like dust, water, and debris—ideal for both wet and dirty environments.
Q: What is the purpose of the garter spring?
A: It ensures uniform radial pressure on the shaft, maintaining a tight, reliable seal during rotation.
Q: Can I use this in a high-speed motor?
A: This seal is suitable for moderate-speed applications. For high-speed systems, consider seals with enhanced heat and pressure ratings.
