Such a construction more fully utilizes the absorbent core, producing cost and weight savings.
According to this, it is possible to achieve weight saving while maintaining rigidity in the front-back direction.
Both a weight saving and an increase in the flexural stiffness can be achieved by a suitable choice of material for the fibre-reinforced plastic with an improved ratio of density and flexural stiffness.
Weight saving of industrial engines.
The radial tire for heavy load is improved in low fuel consumption and simultaneously attains a tire durability and weight saving.
Provided is a heavy-load pneumatic tire, which makes both durability and desired circumferential rigidity compatible while saving weight.
Improvement in thermal efficiency and reduction of operating cost.
Making pollution-causing material harmless.
The voids result in a lower weight product compared with shaft-disk-assembly products made of solid material.
The voids can also function as parts of channels for containing substances.
Clear off the wall of the hollow shaft (6) a solid shaft, or for the purpose of saving weight, a hollow shaft (3) has been fitted in by means of one or more bearings.
The present invention provides a chafer frame with foldable legs that occupies little space when folded, is easy to manufacture, and is light-weight and low-cost.
