DESIGN HIGHLIGHTS
© In the Norton Wheel Spindle Unit design, a ruggedly pro
portioned spindle of toughened, wear-resistant steel runs on a
film of filtered lubricant in long, heavy, hard-bronze bearings.
These bearings provide support over practically the entire circum-
ference of the spindle.
® This Norton unit offers extreme resistance to wheel pressures,
belt pulls, and to those other factors that tend to reduce precision
and shorten life.
•
Long and continuous bearings surfaces confer extreme rigidity
and insure low unit pressure. This low unit pressure helps to
maintain adequate lubrication and sustains efficiency.
O This heavy duty bearing design, plus precision bored casings,
assures permanent alignment between wheel spindle and work
center-lines.
• Over 50% of spindle body sup
ported in tv/o super-duty size, hard
bronze bearings.
• The Norton spindle stays on its fixed
center-line—no shifting is possible.
• Spindle is rigidly supported over
practically its entire circumference.
• Bearing length over twice the diam-
eter—a very desirable feature.
• Bearings automatically flooded
by filtered lubricant.
•
Heavy-duty end thrust bearing at .
center of spindle is flood lubricated.
• Self-contained lubricating unit
within wheel spindle housing delivers
film of filtered lubricant between
spindle and bearings.
