Ceramic roller rings, crafted from fine ceramic (Alumina A/203) boasting a hardness of HRA88, density of 3.85, and an ultra-fine Ra0.2 surface finish. These roller rings incorporate high-speed precision bearings. The ceramic rollers are securely held within a plastic ring to prevent wire from dislodging. The preferred pulley diameters are commonly 15mm and 22mm.
These pulleys are employed in situations involving abrupt changes in direction, effectively preventing wire jumping during the winding process. Crafted from fine ceramic, these wire jump preventers feature surfaces polished to an ultra-fine Ra0.2 finish.
Nozzles are typically employed to guide the wire direction, preventing any insulation damage to enamel wire. Constructed from 99% Alumina with a hardness of HRA88, these nozzles have surfaces polished to an ultra-fine finish of Ra0.2. The favored nozzle inner diameters are 4mm and 7mm.

Carbide nozzles, crafted from tungsten carbide material, exhibit a remarkable hardness of up to HRA90 and above, along with a bending resistance of up to 2300N/mm. The inner bore undergoes grinding and polishing to achieve a smooth Ra0.1 finish, ensuring seamless wire travel and minimizing stress during winding. These nozzles are available in various outer and inner diameters, accommodating different lengths. The most sought-after nozzle sizes are 0.8mm and 1.2mm inner diameter.
