APPLICATION STORY

A laser etching company looked to PBC for a linear solution due to constant ball bearing failure from etching debris in its laser systems. PBC used parallel ceramic coated shafts and self-lubricating FrelonGold® linear bearings in a custom system carriage in order to withstand impending debris and greatly improve accuracy.

Round Shaft Technology utilizes precision round shafting as the guide way, and combines with linear plane bearings or linear ball bearings for movement. While the shafting is often hardened steel, other materials such as stainless steel and aluminum are also readily available. RST bearings and shafting are available in such a wide variety of bearing configurations, and offer solutions for an extensive range of applications. Rail supported round shafting coupled with open bearings offers additional rigidity for heavier loads.
