6 Pcs UHS Radial Shaft Seal 18mm ID x 26mm OD x 5mm W Metric TPU Oil Seal Blue

Standard Size & Universal Fit:Inner diameter 18mm (0.71"), outer diameter 26mm (1.02"), width 5mm (0.20"). This radial shaft seal features a standard UHS (Y-type) profile design, Shore 90A hardness, and is specifically engineered for high-speed applications where optimal sealing performance is critical.

Durable TPU Construction: Made of thermoplastic polyurethane (TPU), this oil seal has excellent mechanical properties, wear resistance, low friction, long service life, and can resist expansion and deformation in standard hydraulic oil. It ensures low friction, smooth reciprocating motion, and reliable air/oil tightness for consistent cylinder performance.

Broad Temperature Range (-20°C to 80°C / -4°F to 176°F): This rod seal is engineered to withstand thermal fluctuations, maintaining consistent sealing performance from cold system to regular working temperatures without hardening or cracking. UHS (Ultra High Speed) radial shaft seals are crucial sealing components in mechanical equipment.

Wide Application:Radial shaft seals are designed to provide an effective seal between rotating or stationary components, preventing leakage of fluids such as oil, grease, or hydraulic fluid and blocking dust and water from entering the machine.

Easy Install: Before installation, apply lubricating grease to the surface of the shaft seal and the bearing to facilitate installation. Steps are as follows: 1. Position the oil seal: Place the oil seal stably in the installation position, ensuring that the oil seal is coaxial with the hole; 2. Apply uniform pressure: Use a special tool or pressure plate to apply uniform pressure to press the oil seal into the hole.
