Plastic Standard Disc Spring Washers. Not for constant spring forces or when high forces are needed.

• Disc spring washer, also known as a Belleville washer, is a conical-shaped washer designed to act as a spring.
• Provides a high spring force within a small space and can be stacked in various configurations to adjust load and deflection characteristics.
• Washers are used to add vibration resistance, preload to bolted assemblies, and to compensate for material expansion or contraction.
• Provides flat spring characteristics and compensates for axial clearances and tolerances. Electrical and thermal insulation.
• Non magnetic - Polysorb(R) material.
