Product details
This aftermarket TC rubber covered double lip oil seal measures 120mm inner diameter, 140mm outer diameter and 15mm in height, manufactured in black NBR nitrile rubber. The steel reinforcing cage is fully encapsulated in rubber, with a primary sealing lip, an integrated secondary dust lip and a garter spring maintaining uniform radial pressure on the shaft.
Importers, wholesalers and MRO buyers can submit RFQ with dimension, quantity, destination and working medium for a formal quotation.
Features & Benefits
Fully rubber-covered outer diameter absorbs housing bore irregularities and provides reliable static sealing, well suited for aluminum housings and light-alloy bores.
Double lip design with a garter spring maintains consistent contact pressure on the shaft; the primary lip retains oil and grease while the secondary lip blocks dust and splash water.
Black NBR nitrile rubber delivers dependable oil resistance and wear resistance, compatible with mineral oils, gear greases and standard hydraulic fluids.
The garter spring compensates for normal lip wear and minor shaft run-out, helping maintain sealing performance over the service life of the seal.
Large 120x140x15mm dimensions suit heavy-duty rotary shafts in gearboxes, wheel hubs and industrial drives where standard metric TC housings are used.
This is an aftermarket replacement seal, not a genuine OEM part. Always verify shaft diameter, housing bore and application before ordering.
Factory standard options are available for marking and packaging; confirm all requirements on RFQ.
