Rotary Shaft Oil Seal | Double Lip | Shaft Diameter (13mm) x Bore Diameter (28mm) x Width (7mm) | Nitrile Rubber Lip Material.
Product Overview:
The Rotary Shaft Oil Seal – Double Lip is a high-performance sealing solution designed to protect rotating shafts from oil leakage and external contamination. With a shaft diameter of 13 mm, bore diameter of 28 mm, and seal width of 7 mm, this component offers a reliable fit for compact and mid-sized mechanical systems across various industries.
This seal features a double lip configuration: the primary sealing lip retains lubricants inside the housing, while the secondary (dust) lip prevents the intrusion of contaminants such as dust, moisture, and dirt. The lip material is made from durable Nitrile Rubber (NBR), which is well-known for its resistance to petroleum-based fluids, wear, and environmental stress. A metal-reinforced outer casing ensures easy press-fit installation and structural stability.

Frequently Asked Questions (FAQs)
Q1: What is the operating temperature range of this NBR oil seal?
A: NBR (Nitrile Rubber) seals typically function between -40°C to +120°C (-40°F to +248°F).
Q2: Why use a double lip seal instead of a single lip?
A: The double lip offers better protection by combining oil retention (inner lip) with dust and dirt exclusion (outer lip), increasing reliability and service life.
