Baltec Ball Material Selection

Ball Screws Ball screws are very similar to ball bearings in that they generally use either chrome steel or type 440C hard stainless steel A peculiarity of ball screws is that they typically have a load ball and the next ball is a 001inch undersized spacer ball and so on

Bowling Ball Coverstock Classifications

Rubber balls were used prior to the 1980s and mostly prior to the 1970s The low friction surface coverstock on a rubber ball actually produces slightly more surface friction than does polyester plastic bowling balls and is similar to the low grade original urethane coverstocks but not as versatile as urethane material coverstocks thus the end of the rubber ball era entirely
