• Available in 55 and 65 Durometer Shore A
• Other elastomer available upon request
• 4 sizes with loads from 1 to 20 pounds
• Static Spring Rate (K Value) is 1/2 to 1/3 the Dynamic Rate
• Fasteners are steel with yellow zinc plating
• 2-D PDF prints are available for each mount
• 2-D DWG, 3-D IGES,  and 3-D SolidWorks are available upon request
• Made in the USA

Natural Rubber (NR)

Advantages:  Outstanding resilience; high tensile strength; superior resistance to tear and abasion; excellent rebound elasticity (snap); good flexibility at low temperatures (-40° to 155° F).

Limitations:

Poor resistance to heat, ozone, and sunlight; very little resistance to oil gasoline, and hydrocarbon solvents; Operating temperatures should not exceed 155° F.

• Natural Rubber is not recommended from exposure to oil, gasoline, ozone sunlight.
• Ring Mounts are not recomened in tension applications.
