GOT-470 Heavy Load type High-temperature Disc Spring Gasket is a looseness-proof gasket designed for bolt and screw connection. It is designed and manufactured according to DIN 6796, and is used for medium or high strength bolt and screw connection, particularly for high temperature and high pressure occasion.
GOT-470H Heavy Load type High-temperature Disc Spring Washer

The large bearing load and elastic recovery make 470 series quite efficient, and the bolt tension can bear the looseness generated by following causes: wearing, creeping, loosing, thermal expansion, shrinking of the easily wear parts, or pressing of the sealing parts. 470 series can increase multiple times of the elasticity performance of screw. It can efficiently substitute the common spring gasket, but not suitable for locking and flat gasket combination.

As 470 series is the involutory or congruent disc spring gasket. The involutory method combination can increase the deformation of the disc spring gasket group, and the congruent method combination can increase the spring power of the disc spring gasket group. The ideal installation method is to press to flat as possible. The more to close pressure status, the faster to increase the tension torque, no need to use the torque banner, can achieve the appropriate bolt tension.

GOT-470L Common Type Low Temperature Disc Spring Gasket

The section of the GOT-470L Low Temperature Disc Spring Gasket is cone shaped, which can bear axial load (static load or alternating load), its characteristic is “working as the maximum load in the minimum room�. The external diameter of the common standard disc spring gasket is ranging from 8.0mm to 600.0mm, and the thickness is ranging from 0.2mm to 40.0mm.
Generally our company produces according to DIN 2093 and GB/T 1972 standard, as well we can carry on the designing task of non-standard disc spring gasket, and the detailed material is also on require. The surface treating methods of the disc spring gasket include bluing, phosphating, electroplating, electrophoresis, and mechanical zinc plating, etc.
