The KOR NBR TC Skeleton Oil Seal is designed for rotary shaft sealing in industrial machinery and automotive systems. Constructed from durable nitrile rubber (NBR), it offers excellent elasticity, oil resistance, and mechanical strength.

The internal metal skeleton reinforces the structure, ensuring accurate alignment and long service life. Its TC double-lip configuration enables dual protection—keeping lubricants in while preventing contaminants from entering. Widely used in motors, gearboxes, pumps, compressors, and mechanical drive systems where reliable sealing is required.
