In the layout of our catalogue, it is veryimportant to us that our customers findthe contents clearly arranged and easy tounderstand, since this product informa- tion is put together with them in mind. The material for spindles and tubes areidentical for a large number of our rollerseries. Essential differences are however found in the bearing assemblies and ma- terials used. A bearing assembly is al- ways the basis for the various roller seriesand characterises our product accordingto application and use in the handling of materials. There are 5 series upon which all our components are based. We have used these to redesign this cataloguefrom the standpoint of application (whichis what our customers know). A bearing assembly essentially deter- mines the technical parameters of a series and significantly influences thefunction of the products. The bearingsemployed in a series are always identical; only structural shapes may vary. The ma- terials for the bearing housing as well as for the industrial seal are likewise always identicalwithin a series. The variations within a series arise from the combination of different spindle and tube dimensions as well as from the different materials. As an example and for better under-standing, here is a brief description of Series 1700, the components of which are the basis for the following Interrollconveyor roller series:
? Universal industrial conveyor roller Series 1700
? Fixed drive conveyor roller Series 3500
? Friction accumulating conveyor rollerSeries 3800
? Tapered conveyor roller Series 1700 KXO and 3500 KXO
? 24VDC RollerDrive All ball bearings of this series are basedon the precision ball bearing manufacturer 6002; only polyamide and polypropylene are used as technopolymers. The characteristics and thus also the applications of the afore-mentioned conveyor rollers are identical,and they are therefore shown together in a series.
