## Overview

The PTFE Shaft Seal HN2390 (45x55x5 mm) is a friction-optimized rotary seal designed for non-hardened shafts, delivering superior sealing performance with a significantly lower coefficient of friction. Engineered to ISO standards, it excels in high-speed and compact applications, making it the go-to choice for professionals demanding durability and efficiency in pressurized media environments.

## Description

Rotary shaft seals with PTFE sealing lips are sealing elements – ready for assembly – which produce the desired sealing effect through radial contact pressure on the shaft. Sealing performance in the receiving hole is achieved by compression fit according to ISO 16589-1. Radial seals with PTFE sealing lips are ideally suited for sealing rotating shafts. The requisite radial contact pressure is assured by selecting the suitable PTFE compound and sealing lip geometry as well as a special manufacturing process. To cover a wide range of application requirements, standard ranges have been developed. Type HN 2390 is used with pressurized media, while type HN 2580 is primarily used for pressureless service and/or with pressures slightly above atmospheric.

## Features

- 45mm x 55mm x 5mm
- HN2390 Friction Optimized
- Vis-à-vis the standard version of type HN 2390 this friction-optimized special type has a significantly lower coefficient of friction
- Suitable for non-hardened shafts
- Also suitable for high peripheral speeds and/or small assembly spaces
