160x185x10.5mm Balance Shaft Oil Seal OEM AZ9114520223 | Brown NBR Aftermarket Heavy Duty Truck Seal

This 160×185×10.5mm TC-type oil seal is a high-quality aftermarket replacement for heavy duty truck balance shaft systems, with OEM cross reference number AZ9114520223.

It adopts a fully rubber-covered skeleton structure with precision-machined sealing lip and built-in high-carbon steel garter spring, maintaining stable radial preload even under continuous vibration of balance shaft operation. It effectively retains gear oil and chassis lubricant inside the shaft housing, and blocks external dust, mud and grit from invading internal components to extend shaft and bearing service life.
