TG 55x70x10mm NBR Brown Corrugated OD Oil Seal

This aftermarket TG corrugated outer diameter oil seal measures 55mm inner diameter, 70mm outer diameter and 10mm in height, manufactured in brown NBR nitrile rubber. It features a corrugated outer diameter, double-lip design with garter spring and an internal steel skeleton.

Importers, wholesalers and MRO buyers can submit RFQ with dimension, quantity, destination and working medium for a formal quotation. Standard production Lead Time is 7–15 days.

Features & Benefits

The corrugated outer diameter resists seal rotation under vibration and accommodates thermal expansion differences between seal and housing, particularly useful in aluminum housings.
Double lip design with garter spring maintains uniform radial contact pressure; the primary lip retains oil and grease while the secondary lip blocks dust and water.
Brown NBR nitrile rubber offers good oil resistance and wear resistance, compatible with mineral oils, gear oils and standard lubricants.
Internal steel skeleton with full rubber coating provides structural rigidity and reliable static sealing in the housing bore.
Standard 55x70x10mm metric dimensions match common TG-type housings used across general rotary shaft equipment.
This is an aftermarket replacement seal. Always verify shaft diameter, housing bore and application before ordering.

Selection & Installation

Selection Tips

Confirm shaft ID 55mm, housing OD 70mm and seal height 10mm. The corrugated outer diameter is designed for press-fit into standard bores. Match NBR material to your lubricant type and operating temperature.

Installation Steps

1. Thoroughly clean the shaft and housing bore; remove all burrs, old seal residue, rust and contamination.
2. Lightly lubricate the sealing lip and shaft with compatible oil. Do not install dry.
3. Press the seal evenly into the housing using a proper installation tool, keeping it perfectly perpendicular to the bore.
4. Do not strike the rubber lip or hammer directly on the seal. Avoid cocking or distorting the corrugated outer surface.
5. After assembly, rotate the shaft by hand to check for binding, then inspect for leakage during initial test run.
