The HFH TSN526S is a robust cast iron labyrinth seal designed to provide effective protection for bearings within SNL and SNH 526 series plummer block housings. With an inner diameter of 120mm, an outer diameter of 140mm, and a width of 15mm, this non-contact seal efficiently prevents the ingress of contaminants such as dust and moisture, while ensuring optimal lubricant retention. Its durable construction makes it ideal for demanding industrial applications, significantly extending bearing service life and reducing maintenance requirements.
