High quality spring washers : Belleville washers
Founded in 1933, BORRELLY SPRING WASHERS SARL has specialised since the seventies in developing and producing spring washers. Over time, it has developed numerous products, including Belleville washers. In order to offer its clients Belleville washers that are at the cutting edge of technology, the company’s policy of innovation requires the continuous development of its technology and human resources .We offfer our customers a recognised expertise and a worldwide reputation in our field.
Borrelly develops and produces very high quality like Belleville washers : spring rings, steel washer, wave spring washer... Borrelly is directly involved during the design phase and is recognised by the leading companies in the fields of Formula 1, aeronautics, the nuclear industry and aerospace whilst not forgetting industrial valves and automobiles. Designing Belleville washers require thorough knowledge of the product, acquired through years of experience. This is why each manufacturing phase for Belleville washers is completely done in the company factories (design and production of tooling, cutting, stamping, heat treatments).
Belleville washers applications Belleville washers are round elastic parts wich can strore a maximal amount of energy for their unit volume and wich are ideal for highly complex problems.
For exemple :
Problem to be solved : Attenuate noise from a rotary hammer on an impact driver, whilst delivering sufficient energy to operate the system.
Constraints: Combine spring function with reduced noise and improved comfort of use.
Solution: Belleville spring washer using composite materials
Borrelly added value: Prototyping of washers followed by fatigue testing. Materials developed specifically for noise reduction and impact shock absorption applications.
Our skilled teams can provide solutions for delicate problems in all high-tech fields, including the offshore, nuclear and aerospace industries.
For prototyping and small production runs, we regularly use materials designed to withstand extreme environments (high or cryogenic temperatures, chemical substances), such as:
• INCONEL 718
• Beryllium copper
• Austenitic and martensitic stainless steels
• Structurally hardened stainless steels
• Special steels such as 45SCD6, 50CV4, XC75
• Composite materials
• INCONEL 750
• Titanium
• Nimonic 90
• Hastelloy
