Wiper K10 50x58x6/8

The K10-50×58×6/8 wiper ring is a single-acting protective element for hydraulic cylinders, made of NBR (nitrile rubber) in the NB9001 compound of increased hardness. The profile removes solid contaminants, dust and moisture from the extending and retracting piston rod, which protects the sealing assembly and the working fluid from degradation. The K10 profile is built around a flexible wiping lip with an optimized cross-section and an additional inner sealing lip. The double lip geometry removes foreign particles from the piston rod surface effectively while retaining the oil film inside the system, reducing the risk of stick-slip. The outer edge provides stable seating in the closed gland groove without the risk of the ring twisting during cyclic operation. Technical data and dimensions: Piston rod inner diameter (d): 50,0 mm Housing outer diameter (D): 58,0 mm Ring height (h): 6,0 mm Total height / groove (H): 8,0 mm Dimensions in inches (d × D × h/H): 1,969" × 2,283" × 0,236" / 0,315" Profile type: K10 (Double Wiper) Material: NBR (material code: NB9001) Brand: Kastas Application: protection of the hydraulic system in cylinders and actuators Compatibility: mineral hydraulic oils (DIN 51524), HFA, HFB, HFC emulsions
