te.com LBB ULTRA-PRECISION GAGE HEADS SPECIFICATIONS Spring and pneumatic extend versions Linear ball bearing front end Extremely long life cycle 0.000004 inch 0.1m repeatability 0.02 to 0.1 inch 0.5 to 2.5mm ranges Replaceable tungsten carbide contact tip Double shielded LVDT Flexible cable, resistant to chemicals Fluoroelastomer boot (Model dependent) Selection of optional electrical connectors The Linear Ball Bearing (LBB) Ultra-Precision gage heads are dimensional gaging probes engineered for highly precise and repeatable Features measurements in quality control and metrology applications. The linear ball bearing system within the gaging probe reduces radial play to a 0.000004 (0.10m) repeatability minute level and minimizes friction for ultra-precise measurement. Housing diameter options: Smooth 0.315 The bearing assembly utilizes two circumferential rows of miniature 8mm & 3/8 9.5mm , or threaded 3/8-40 balls. The balls ride on a non-rotating plunger. The plunger is hardened UNS-2A to Rockwell 65, hard-chrome plated and precision ground for optimal Four electrical connector options (cable end) repeatability and resistance to brinelling. The contact end of the plunger has a removable tungsten carbide ball tip. Plunger and bearings are Optional contact tips (4-48 UNF-2A threads enclosed in a cylindrical housing, hand-honed and fit to the ball bearing only) assembly. Precision fitting provides for exceptional repeatability. With Adapter provided for radial cable exit the bearings and housing matched in hardness, the plungers can better (Selected models) tolerate side loads for a longer life cycle. Compatible with all our signal conditioners A Linear Variable Differential Transformer (LVDT) is contained in the Calibration report supplied with each unit opposite end of the tubular housing. With no physical contact between its core and coils, the LVDT produces a highly repeatable output voltage proportional to displacement. Applications LBB gage heads feature a unique two-piece construction and are Online inspection of automotive parts reparable should either probe structure or cables become damaged. A Process feedback for numerically-controlled bend relief spring (on selected models) protects the cable at its exit. Positive mechanical stops prevent damage to the LVDT from impacts at machine tools the end of the contact tip in cases of over-stroke. Dimensional inspection of precision parts Point-of-manufacture status of production Spring-extend LBB gage heads feature user adjustable pre-travel/over- travel settings. Air-extend, spring-retract units require dry, oil-free air at process standards 5 to 15PSI 0.34 to 1bar by varying air pressure, users can control the Automated data collection for factory SPC gaging force to ensure that the probes do not damage finely finished Robotics surfaces or distort delicate parts.
