Balls
JSC "OK-Loza" offers balls of different degrees of accuracy with diameter from 0.25 up to 60  mm.
They are made of different materials: high-quality chrome-plated steel,  silicon-molibdenum
steel, low-carbon steel (for hunting shot), aluminium,  brass, ceramics and polymers.
The price depends on requirements and is agreed upon with each customer particularly.
Deviation of mean diameter, multidimension of balls to diameter in a lot , inconstancy of
 isolated diameter, deviation from spherical shape and surface irregularities do not exceed
values listed in the table below (GOST/All-Union State Standard/ 3722-81):
