Product description

Calculation of shear force; F= p x D x L x n
F= maximum shear force (N)
p = maximum surface pressure (N/mm2)
D x L= projected area (mm2)
n= quantity of rings
Easy working of the fitting groove and assembly.
High load-bearing capacity.
Low coefficient of wear and low coefficient of friction (between 0.05 and 0.1) available in many sizes.
Ordering information
