Movable rollers allow a little misalignment between the opposite mounted guide rails. High temperature On request guide rollers can be equipped with Viton seals to operate at temperature up to 120° (suffix V). Check in the dimensional table component availability. Accessories Tables and carriages Standard table and carriages for C-DC and LM systems incorporate a black anodised aluminium plate fitted with guide rollers. Wipers Standard wipers NAID for C-DC rails are made from NBR compound moulded on a steel plate. Lubricators Are composed by two main parts: a plastic box with the same shape profile of the rail, and a lubricated felt; the felt is slightly pressed on the raceways by a spring. The plastic box, that drags the raceways, works as a wiper, and remove dust and shavings. The plastic box can be mounted directly on the guide rollers plate by the appropriate aluminium plate included in the kit. In the lubricators for guide rollers size 52 or higher, the grease nipple allows an easy connection with a re-lubrication system. For the simply lubrication of the rails you can use one lubricator only on each raceway; in order to wipe the raceways it is better to mount two lubricators, before and after the carriage. The lubricators are supplied with the felt already lubricated. FS / FRN...EI FS / FRL... _ Another solution is to use one profiled guide rail e.g. FS and on the opposite side a flat rail e.g. GP in connection with rollers GC or PK. Technical features Lubrication Guide roller FRN..EI permits bearing relubrication. All other guide rollers are long life lubricated. Temperature Guide roller should not operate at constant temperature above 80°C. For short durations 100°C can be accepted. For higher temperature please see the "option section". Speed limit Max velocity has to be determined for each application relevant to the guide roller type, size and load conditions. As general value, in normal conditions maximum speed is 4 m/sec but, with the correct chose of the components, the speed can reach 10 m/s. Contact Nadella Technical service in case of specific request. Options Corrosion protection For uses in oxidising environments or in the presence of corrosive agents, the guide rollers are available in stainless steel (suffix NX) the guide rollers with tapered rollers (RKU, RKY/X, FKU, FKY/X) and needles (FRN) are equipped with standard bearings.
