The ball is mounted in a plastic shell so as to be freely movable, which enables rolling and therefor generally optimizes the locking characteris- tics. Above all, this reduces wear on the counter piece. A further characteristic of these plungers is that the plastic bearing acts as an electrical insulator. see also... • Spring Plungers GN 615 (Ball without Friction Bearing) → Page 976 Information • Type K / KS - - Housing steel, blackened - - Ball steel, hardened • Type KN / KSN - - Housing stainless steel AISI 303 - - Ball stainless steel AISI 420C, hardened • Pressure spring Stainless steel AISI 631 • Friction bearing - - Plastic - - Temperature resistant up to 90 °C • Identification of type KS / KSN: Housing with 2 longitudinal markings • Stainless Steel Characteristics → Page 2166 • RoHS Specification 1 d 1 2 Type How to order (With slot) 1 2 GN615.8-M8-K GN 615.8 GN 615.9 Spring Plungers with Slot with Internal Hexagon Steel / Stainless Steel, Ball with Friction Bearing 1 d 1 2 Type How to order (With internal hexagon) 1 2 GN615.9-M6-KN
