Rotary Shaft Oil Seal | Double Lip | Shaft Diameter (31.75mm) x Bore Diameter (50.8mm) x Width (6.35mm) | Nitrile Rubber Lip Material.
Product Overview:
The Rotary Shaft Oil Seal (31.75mm x 50.8mm x 6.35mm) (equivalent to 1.25" x 2" x 0.25") is a precision-engineered sealing component designed for small to medium-sized rotating shafts. Featuring a double lip design, this seal effectively retains lubricants while keeping out contaminants such as dirt, water, and dust. Manufactured from Nitrile Rubber (NBR), the seal offers excellent resistance to petroleum-based oils, greases, and light chemicals. Ideal for industrial, automotive, and agricultural applications, it is optimized for durability and reliable performance in tight mechanical systems.

❓ Frequently Asked Questions (FAQs)
Q1: What is the purpose of the double lip design?
A1: The double lip consists of:
-
A primary lip that retains lubricants (oil or grease)
-
A secondary lip that blocks out dust, dirt, and moisture
This dual-sealing system extends the lifespan of machinery and reduces maintenance.
Q2: Why is Nitrile Rubber (NBR) used for the lip material?
A2: NBR is selected because it:
-
Resists petroleum-based oils and greases
-
Handles abrasion and wear effectively
-
Performs well in a temperature range of -40°C to +100°C
It’s a cost-effective, reliable material for general-purpose seals.
