Piston Seal KDSB 50x34x20,5

KDSB piston seal 50x34x20,5 (code: KDSB 0500 0340 205 CX) belongs to the KDSB group of compact seals designed for hydraulic cylinders. Construction: a central NBR rubber element (70 ShA) performing the main sealing function, side rings made of thermoplastic elastomer (TPE), acting as anti-extrusion rings, outer guide rings made of polyacetal (POM), which keep the piston centred in the cylinder. Material – code CX. Operating parameters: Working pressure: up to 400 bar Medium: mineral hydraulic oils Appearance and principle of operation: The KDSB seal has a multi-element design. The central rubber element provides the seal, the side rings prevent extrusion, and the POM guide rings maintain stability and guide the piston. It can be installed in both a closed groove (one-piece piston) and an open groove (split piston). Technical data: Piston outer diameter (D): 50 mm Inner diameter (d1): 34 mm Height (H): 20,5 mm Size in inches: 1.97x1.34x0.81 (DxdxH)
