DescriptionWith increased WLL in axial direction and when load ring is aligned. For all loads, which have to be flipped and turned-over. Loadable in any direction: safety factor 4. Can also be supplied with longer thread lengths. The bolting position has to be designed in such a way that the introduced forces are accommodated by the work piece without being deformed. Pay attention to a plane surface. Blind holes have to be drilled deep enough to make sure that bolt-on flange has a proper support. Minimum steel quality 1.0037 (St 37). When using light metals, non-ferrous heavy metals, and grey cast iron, the thread classification must be chosen in such a way that the WLL of the thread is according to the strength of the base material. Due to the ball bearings, for a normal single lift, tightening with a wrench without an extension acc. to DIN 895 respectively DIN 894 is sufficient. The VWBG must have full support on the bolt-on surface (D) without using a shim ring. If the VWBG stays permanent at the load, tensioning with a torque of 550 nm is required. In case of shock loading, twisting or vibrating, especially with through hole bolt connections using nuts, an unintentional dismounting may occur. Securing possibilities: a liquid locking glue, e.g. Loctite (read the instructions of the manufacturer), or a mechanical form locking bolt device, e.g. a crown nut with a cotter, should be used. |
