TG 32x52x7mm NBR Rubber Coated Oil Seal Rotary Shaft

This aftermarket TG corrugated outer diameter oil seal measures 32mm inner diameter, 52mm outer diameter and 7mm in height, manufactured in NBR nitrile rubber. It features a corrugated or threaded 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 improves press-fit stability in the housing bore and resists seal rotation under vibration, making it suitable for housings with thermal expansion variation such as aluminum.
Double lip design with garter spring: primary lip retains oil and grease while the secondary dust lip blocks contaminants from reaching the sealing contact area.
NBR nitrile rubber offers good oil resistance, wear resistance and aging resistance, compatible with mineral oils, greases and standard lubricants.
Internal steel skeleton with full rubber coating provides structural rigidity and reliable static sealing between the seal outer diameter and housing bore.
Standard 32x52x7mm 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.

Aftermarket replacement. Verify shaft diameter, housing bore and application before order.

Selection & Installation

Selection Tips

Confirm shaft ID 32mm, housing OD 52mm and seal height 7mm. 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.
