Precision Balls

Nylon Balls



General Information:
Nylon Balls are used in valves, light-duty bearings, flowmeters and numerous special applications where toughness, abrasion resistance and light weight are more important than hardness.
Basic Composition:
Du Pont Nylon Resin Zytel  
(or similar material)  
Mechanical Properties:  
Hardness 118 Rockwell 'R'
Density 0.041lbs/cub.in.
Specific Gravity 1.14
Water Absorption (24hrs) 1.5%
Max. Useful Temperature 148 Deg.C (300 Deg.F)

Size Range:  
Imperial 3/32" to 2" inclusive
Stocked Sizes 3/32" to 1" inclusive - Larger sizes to order
Tolerances: 3/32" to 1/2" 9/16" to 1"
