Metric Oil Seal

TCM Metric Oil Seal

The TCM / Dichtomatik 25X52X7TC Metric Oil Seal is a precision rotary shaft oil seal designed to retain lubricants while preventing dirt, dust, and moisture from entering mechanical assemblies. Manufactured by Freudenberg NOK, this seal features a double-lip nitrile (Buna-N) sealing design that provides reliable oil retention along with added protection against contaminants. Sized for a 25 mm shaft with a 52 mm housing bore and 7 mm width, this seal is commonly used in motors, gearboxes, pumps, and agricultural equipment where dependable sealing performance is essential—because machinery runs best when the oil stays inside and the dirt stays outside.
