Simplified lubrication management
A-19
NB's fiber sheet is material with a porous structure containing the lubricant oil. The oil is supplied to the ball
elements at the proper time and in the proper amount by the principle of capillarity, greatly increasing the
intervals between when oiling is required.
Figure A-32 Degreased model durability test
SGL35F model, tested without grease.
Operation failed several hours after
start of test.
An acceleration test was performed with oil absorbing material sprayed on the units to validate the GL type's
lubrication performance and durability even under poor operating conditions.
