GN527.1 Handwheel, Plastic, Crenelated Rim, Plain or Threaded Through Bore
These hand wheel have a crenelated rim for a good grip. They are very sturdy and strong and can be used either as a control wheel or for clamping purposes.
Worth mentioning is the deliberately large hub bore. They also lend themselves to applications where a large contact face or a large bore is required. The visible blackened contact faces of the steel hub are perfectly machined which gives the product a good appearance.
Plastic Technopolymer (Polyamide PA), glass fibre reinforced, Temperature resistant up to 120°C, black, shiny finish.
Hub - steel ST, blackened.
