Frequently asked questions
Why are cast sprockets less precise than turned and milled ones?
Cheap castings have a rough tooth surface, hidden air bubbles and slight deformations. CNC-turned and milled sprockets mean a smooth working surface, perfect alignment and safety for the most expensive machines.
How do I select a sprocket with bearing for a tensioning system?
An idler sprocket (with built-in bearing) is selected according to the pitch of the working chain and mounted on the slack side (not on the tight side). It is important that the bearing is protected against dust, especially in agricultural machinery.
Does Ozdowski have its own warehouse and fast shipping of parts?
Yes - we know that every minute counts during a production line breakdown, which is why we keep large stocks of sprockets available immediately, allowing lightning-fast shipping and a quick solution to the drive problem.
How do you cut a keyway in the hub of a sprocket?
We cut keyways precisely on slotting machines according to DIN 6885. If you do it yourself, maintain axial alignment and the correct width and depth of the keyway so that the key sits securely and is not sheared off.
Where is this product used?
12B-1 sprockets operate in the drives of construction machinery, goods lifts, aggregate conveyors and woodworking machines - wherever tooth durability under heavy load matters.
