Koło zębate hartowane z kołnierzem 20B-1 (R1 1.1/4) Z-30 Waryński

Hardened sprocket with flange 20B-1 (R1 1.1/4) Z-30 Waryński Universal sprocket with hub with hole for turning. Suitable for chains of the PN77/M-84168, DIN 8187, ISO 606 standards. Increased abrasion resistance. Induction hardening of teeth makes the wheels have a longer service life and are more resistant to abrasion. This process takes place under special supervision, thanks to which ideal parameters of the furnace and cooling liquid are ensured. Extended service life. This is due to the precision of the teeth, pitch and pitch diameter, thanks to which the chain works with the wheel without unnecessary resistance. This prevents abrasion of the rollers and stretching and damage of the chains. Increased resistance to cracking. All wheels are made of high-carbon steel. Very good cooperation with Waryński chains. Accurate and repeatable distances between teeth ensure that the chain fits perfectly on the wheel, without damaging the chain.
