Continued on next page... Load Values for Stainless Steel approximate 95% of Spring Steel values shown. Disc springs can be used singly, or may be combined to make a stacked spring column. d h D O.H. t DISC SPRINGS - for BOLTS Materials: 1075 high carbon steel or 6150 chrome vanadium steel, plain or phosphate finish, our option. Series AI pre-stressed disc springs are used to maintain load or tension in bolted assemblies. Pressure begins at the outer radius and flattens gradually toward the bolt as deflection progresses. Disc springs exert a uniformpressure that remains constant in spite of tension losses caused by thermal expansion and contraction, compression set, or wear of parts. Because pressures are predictable, disc springs provide a simple and effective means of determining bolt tension that is far more accurate than “torque” readings. 680-B13-1K 680-B02-1W 502523 1/4" .500 .258 .023 .016 .039 130 .012 160 .016 680-B04-1Y 502538 1/4" .500 .255 .038 .010 .048 344 .008 454 .010 Contact Sales Desk For Package Quantities See Page D45-D47 for Technical Data 16 Jan 2018 Conform to MIL-W-12133/1"B" Material and finish must be specified on order. ● Rondelles à ressort (Belleville) F : 1- 8-252-6380 service@spaenaur © 2018 Spaenaur Inc.
