Description
Rotary Shaft Oil Seal | Double Lip | Shaft Diameter (54mm) x Bore Diameter (68mm) x Width (7mm) | Nitrile Rubber Lip Material.
Product Overview:
The Rotary Shaft Oil Seal TC54×68×7 mm combines a double-lip layout with a nitrile rubber (NBR) sealing element and a steel-reinforced shell. The primary lip retains oil or grease, while the secondary dust lip blocks water, dirt, and abrasive particles. An internal garter spring maintains constant radial pressure on the shaft, guaranteeing a tight, long-lasting seal in both dynamic (rotating) and static conditions.

❓ Frequently Asked Questions (FAQ):
Q1: What advantages does the double-lip (TC) profile provide?
A1: One lip holds lubricant in, while the second lip acts as a wiper to keep out dust, dirt, and moisture—prolonging bearing life and reducing maintenance frequency.
Q2: Why choose Nitrile Rubber (NBR)?
A2: NBR offers excellent resistance to mineral oils, greases, many hydraulic fluids, and mild chemicals, while remaining flexible over a wide temperature range (–40 °C to +120 °C).
