Order and request forms available at: www.hema-schutz.de DURASPRING Spiral Springs are commonly used for the durable protection of ballscrews and shafts. DURASPRING Spiral Springs are produced using spring steel. The steel strip is roll formed to produce the spiral spring. The advantages of DURASPRING are: High quality spring steel Tandem installation of multiple springs is possible Retrofit possible Special oil for enhanced life Production certified according to ISO 9000:2008 Anti-corrosive packaging DURASPRING Spiral Springs are available in two versions: DURASPRING BLUE - standard spring, blue steel DURASPRING SILVER - stainless steel version If the spiral springs are exposed regularly to coolants with a high proportion of water, then stainless steel band should be used. Stainless spiral springs have lower spring forces and therefore cannot be manufactured in all sizes. We use spring band steel of extreme hardness (55-58 Rockwell) with chamfered edges and a strength of up to 1800 N/mm² for our standard spiral springs. Band steel in thicknesses from 0.2 to 1.0 mm will be selected in accordance to size and application. Since this is docucumented within our quality system, reproducibility is also guaranteed when reordering. Dimensions The standard range now comprises springs in dimensions from 15 mm up to 160 mm internal diameter. Special dimensions are available on request. Spiral springs for vertical use can be produced up to an extended length of 4500 mm. Speed DURASPRING is designed as standard for speeds up to 40 metres/minute. Special solutions with almost twice the speed are achieved in individual robotics applications. The optimum operating conditions for DURASPRING is in applications with oil. Bellows should be used alternatively for fine particles and dust. Maintenance/Cleaning Decisive factors in assessing the quality of spiral springs are the smoothness of travel, and even consistency of the overlapping turns. The quality of each DURASPRING is assured with the aid of our testing machines. Each spring is tested for its running properties prior to despatch. Maintenance of the springs is necessary. Cleaning the springs according to the degree of contamination and then applying a light oil film is recommended. Available for this purpose is DURASPRING LONGLIFE special oil. Please pay attention to the mounting and maintenance information supplied with each shipment.
