SP ProTwist aids installing, moving, and realigning CNC machine tools. This easy-to-use system is suitable for any quality management process, offering precision measurements down to 1µm (0.2 arcsec). Consisting of two µLevel Spirit Levels, it uses Bluetooth technology to communicate to the Android-based Smartphone or Windows-based PC for fast, efficient measurement of straightness and parallelism. It can also provide simultaneous measurement of pitch and roll, as well as differential measurement.
SP ProTwist can be used as a stand-alone instrument, or in conjunction with advanced software that guides users through each step and documents the results. Each µLevel can be used independently or together when one unit serves as a continuous reference.

Crossed-roller linear bearing
The stainless steel, NB Studroller is suitable for use in highly corrosive, hot environments or vacuums.
This crossed-roller linear bearing is for motion control applications with fast acceleration and deceleration (at dimensions from 30mm to 600mm lengths, 1mm to 12mm rollers, endurance is 150 million cycles). NV type Studroller with stainless steel uses anti-creep cage technology.
Placing studs in the center roller and machining a correspondingly dimpled path in the rail produces a retainer that never slips.
Load capacities are increased 1.4x to 2.3x compared to the standard SV type. Roller-to-rail contact area is extended 42% to 58% while the roller number is increased 20% to 55%.
