ASSEMBLED UNITSTECHNICAL DATAMiniTec Quattro linear slides are ideal solutions. The combination of precision linear bearings withintegrated seals and exactly matched housings ensure optimum positioning characteristics.Quality-monitored series production of all components is the basis for uniform precision and costeffectiveness.The massive outer shell of the linear bearings, of ball bearing steel in combination withchromium steel balls of Class II and cages of heat-stabilised PA 66 guarantee outstanding quiet operation.MiniTec Quattro linear slides provide a wide variety of applications, particularly in the area of handling.Temperature range:-20 to +100 °C; for higher temperatures the use of bearings with steel cages is necessary.Shaft Deflection:When selecting closed Quattro linear slides, the maximum permitted shaft deflection of 0.5° must be takeninto consideration. The deflection can be calculated by the following formula*:F Load (N)a Round gap of first ball bushing (mm)b Middle gap of ball bushing (according to Table 1)E • J Value from Table 1tan α =F • a • b4 • E • Jshaft Ø mm E • J (N mm 2 ) B8 4,222 • 10 5 3512 2,138 • 10 6 4516 6,756 • 10 6 5620 1,649 • 10 7 7125 4,027 • 10 7 8830 8,350 • 10 7 9640 2,639 • 10 8 13450 6,443 • 10 8 156aFFbLFaDynamic load ratings and weights:• Dynamic load ratings according to ball bushing used; see Pages 10 - 19• Weights of slides and traverses can be found on Pages 74 - 79*Intrinsic weight of shafts and slides is not taken into consideration.MINITEC LINEAR SYSTEM 73
