Specification
Information

Base and tapped socket: Stainless steel, European Standard No. 1.4305 (American Standard Series 303)
Available types:
--Without cap
--Plastic cap: Technopolymer plastic, DELRIN®, white (natural color)
--Plastic cap, electrically conductive, surface resistivity < 106Ω, volume resistivity < 107Ω
--Rubber cap: Thermoplastic TPE rubber, 78 Shore A hardness, black
--Rubber cap, electrically conductive, surface resistivity < 106Ω, volume resistivity < 107Ω

GN 343.5 leveling mounts can bear high static loads, but for high loads, they should be used in conjunction with screws of high tensile strength. Recommended are DIN 915 dog point socket set screws, available upon request. The dog point must be seated squarely at the bottom of the threaded hole, which will increase the load capacity of the ball in the socket.
The load values in the table apply only to versions without cup and with plastic cup.
Mounts are supplied assembled.
*Load values in table valid only for without cap and with plastic cap types.
