Linear Slides

Page 11 Specifications subject to change without notice or incurring obligations ring longer strokes & more features than other block-style slides Load Limits: Safe loading involves a combination of factors including: bearing capacity, shaft strength and allowable deflection, life expectancy, how the load is applied, and how fast the load is accelerated/decelerated. DO NOT OVERLOAD – Overloading can cause reduced product life, shaft bending and loss of position accuracy, as well as seal and bearing failure. CAUTION : Heavy reciprocating loads can cause damaging impact forces at end of stroke. It may be necessary to use stop collars and/or bumpers, or reduce speeds to avoid damage to slide and/or tooling. Load Sizing Guide GB Series LOAD FULLY EXTENDED P ressure Rating: Maximum operating pressure is 150 psi Air Output Force: Output Force = Pressure X Power Factor Speed: Safe speed range is determined by a number of factors. The most important consideration is total reciprocating weight. High loads combined with high speeds can develop severe and damaging impact loads. For speeds over 10 inches per second use extend bumpers (Options "A" or "B"). Accuracy: GB Series Slides feature replaceable, high performance, self lubricating Duralon ® sleeve bearings and special ground guide shafts. Straightness tolerance is .0015" per foot of guide shaft. Repeatability of extend stroke is .001" with Option "D".
