Rod seal K38 35x45x10

The K38-35x45x10 PU U-ring (also designated K38-035/2 PU in the manufacturer catalogue) is a single-acting lip seal designed for use in hydraulic systems. The profile design features symmetrical sealing lips of equal length and a deep internal groove, which helps reduce friction during linear motion. A design feature of this model is an integrated additional sealing lip located on the dynamic outer diameter. The purpose of this additional lip is to collect the oil film, stabilise the position of the seal in the seat and limit the ingress of small contamination particles from the wiper side. The product is made of thermoplastic polyurethane (TPU) with a hardness of 94 Shore A. This material is characterised by a high modulus of elasticity, a low compression set and resistance to abrasion, tearing and shearing. The seal shows chemical compatibility with mineral and hydraulic oils. The symmetrical cross-section makes installation in closed seats easier and prevents the ring from twisting during installation. Technical and dimensional data: Inner diameter (d): 35 mm Outer diameter (D): 45 mm Height / thickness (H): 10 mm Dimensions in inches: 1.378 × 1.772 × 0.394 in Material: Polyurethane (TPU 94 Shore A) Working pressure (maximum): 400 bar Travel speed (maximum): 0.5 m/s Installation recommendations: Before installation, remove all burrs, sharp edges and machining residues from the seat and the shaft. To make it easier to seat the seal in the groove and to protect the lips from damage, coat the element with hydraulic oil before installation.
