Rotary Shaft Oil Seal | Double Lip | Shaft Diameter (28mm) x Bore Diameter (37mm) x Width (4mm) | Nitrile Rubber Lip Material.
Product Overview:
The Rotary Shaft Oil Seal (28mm x 37mm x 4mm) is a compact, double-lip seal engineered to provide reliable lubricant retention and dust exclusion in tight, precision-built environments. Featuring a nitrile rubber (NBR) sealing lip and a steel-reinforced casing, this seal is ideal for low-profile housings and space-constrained systems.
The double-lip configuration includes a garter spring that applies constant pressure on the shaft, ensuring excellent dynamic sealing. Whether you’re sealing shafts in motors, gearboxes, or pumps, this seal is built for dependable performance in moderate-speed, low-pressure rotary systems.
