Professional Applications & Engineering Value

This precision steel washer delivers exceptional engineering value in 35mm shaft applications where dimensional accuracy is critical. The DIN 5405-3 and ISO 303 compliance ensures reliable performance in rotating machinery, automotive systems, and industrial equipment. The carefully controlled ID tolerance (0-0.25mm) prevents loose fits that could cause misalignment, while the OD tolerance (-0.3 to -0.05mm) guarantees proper seating without interference. The 1mm thickness with ±0.05mm tolerance maintains consistent spacing in stacked assemblies. Manufactured from high-grade steel, this metric washer withstands heavy loads and harsh operating conditions, making it ideal for mechanical engineering applications requiring precision and durability.
