Derived from nature’s hardest substance, John Crane Diamond uses ultrananocrystalline diamond (John Crane Diamond®) treatment—a thin film of genuine diamond that is grown via chemical vapor deposition on the seal face. Only John Crane integrates this technology directly into our manufacturing process, bringing you unmatched expertise in seal and face treatments with best-in-class adhesion.
John Crane Diamond is available on sintered silicon carbide and tungsten carbide substrates offering performance benefits in a wide range of applications in nearly every industry.
John Crane Diamond delivers essential benefits:
– Increased durability: This pure diamond film delivers unmatched hardness and superior chemical stability to increase seal durability and longevity.
– Increased reliability: Rigorous controls assure film crystallinity, thickness, and consistency.
– Reduced costs: The low coefficient of friction results in cooler running faces, reduced power use, and lower lifecycle costs.
Increased productivity: Mission-critical equipment stays up and running, helping you achieve production goals.
