KRO series for round belts: driven tapered rollers with two grooves head
Driven tapered rollers with two grooves head for round belt transmission
These rollers are ideal to build curves in light unit handling and are obtained by keying Polypropylene cone sleeves on the base rollerO 50. On the side of the smaller diameter there is a sprocket with 2 grooves for round belt transmission O4-5 mm, interchangeable with other heads, thus avoiding deformations as in case of grooves on the tube.
The sprocket is made in black Polyamide, while the general features are the same as for the driven sprocket tapered KRO series (base roller 135 series) but with a different lay-out. The rollers have precision radial 6002-2RZ bearings.
