LINTECH ® Standard Positioning Components Shafting - Inch and Metric LINTECH's precision "cut to length" 1060 carbon steel inch and metric shafting is manufactured with the highest standards for surface finish, surface hardening, roundness and straightness. These manufacturing procedures provide a quality shaft with long life and optimum performance in todays demanding applications. Inch diameters are available from 0.25 to 2.0 inches in class L, S and N diameter tolerances. Metric diameters are available from 8 to 50 mm. Any length is available within .001 inch increments, up to the...

LINTECH ® Standard Positioning Components LBCA & LBOA Precision Linear Bearings LINTECH's LBCA & LBOA offer an "all steel" linear bearing design. This provides for operation in high temperature environments (up to + 600o F) and can offer a smoother operation when compared to the LBC & LBO style bearings for some applications. A LBC, LBO & Metric Linear Bearings LINTECH's high capacity linear bearings have a ball conforming outer race coupled with a self-aligning feature which allows for zero bearing clearance while maintaining smooth operation. The independently self-aligning outer bearing...

Design Considerations Product Description Precision Steel Shafts LINTECH's precision shafting, SA and TRSA shaft assemblies use Rockwell 60-65C hardened and ground shafts. These high quality carbon steel shafts are accurately machined and heat treated for uniform hardness. They are also inspected for straightness, roundness, and smoothness. The high hardness and extremely smooth surface of the steel shafts creates an abrasion-resistant surface, which reduces material wear and system friction, while maintaining an optimal surface finish. Inch and Metric shaft diameters are available in...

Design Considerations Product Description Precision Steel Linear Bearings Self-Aligning Linear Bearings LINTECH's LBCA and LBCO precision steel linear bearings LINTECH's LBC, LBO, and metric linear bearings consists are manufactured with high quality steel that is hardened and precision ground. The recirculating precision ground bearing balls roll freely into and out of the load zone. The balls are guided through their recirculation path by a steel retainer and hardened sleeve. These bearings are used in high temperature applications and where self alignment is not required. of a wear...

Design Considerations How to Select a Positioning Component Travel Life Required Life Examples The rated life of a linear bearing, pillow block or carriage assembly is measured in inches (or km) of travel under a specified load. The failure of a linear bearing system occurs when the operating stresses from the rolling balls in the linear bushing cause material fatigue, resulting in flaking of the steel balls or steel shaft and/or grooving in the steel shaft. Below are two examples which illustrate the importance of a dynamic load rating based upon travel life. These two applications could...

Design Considerations Load Capacities Safety Factors Dynamic Load Capacity As a practice, safety factors should always be used when selecting a linear bearing, pillow block or carriage assembly for a given application. For most real world applications people do use safety factors. However, sometimes the incorrect safety factor or no safety has been used. This can lead into an unexpected system failure. LINTECH provides, in a chart form, different safety factor recommendations for linear bearings, pillow blocks or carriage assemblies. Keep in mind that these recommendations for safety...

Design Considerations Load Capacities Hardness factor - FH Temperature factor - FT The maximum travel life of a linear bearing is achieved when the shaft surface has a hardness value greater than (>) Rockwell 60C. This hardness assures that no shaft grooving or flaking will occur under normal operating conditions. Ambient temperatures over 2120 F (1000 C) will fatigue any linear bearing system, and will cause a decrease in travel life. Please note that some LINTECH linear bearings, pillow blocks and carriage assemblies have a maximum operating ambient temperature of 1850 F. Therefore these...

Design Considerations Load Capacities Load direction factor - FL The maximum travel life of a linear bearing, pillow block or carriage assembly may need to be de-rated depending upon the direction the load is applied to the bearing. The Polar charts shown below for each bearing type indicate the de-rating factor (or multiplier) based upon the direction the load is applied to the bearing. In most applications not all the bearings will see the same applied load, so you can use the adjacent equation to determine the estimated life based upon the heaviest loaded bearing or the bearing which...

Design Considerations Load Capacities Lubrication Frictional Resistance LINTECH shafts, shaft assemblies, linear bearings, pillow The total friction resistance of a LINTECH linear bearing, pillow block or carriage assembly can be calculated by using the following equation. blocks or carriage assemblies require a small amount of grease or oil for proper, long term operation. Lubrication will decrease system wear and the potential for rusting of shafts and linear bearing surfaces. For most applications a medium to heavy oil, light grease, or silicone based lubricant is recommended. The many...
