2 Linear Motion and Assembly TechnologiesTychoway Linear Roller BearingsThe extremely low friction of Tychoway Linear Roller Bearings enables them to provide very accurate positioning in machine slides by virtually eliminating the stick-slip phenomenon. The combination of positioning and travel accuracy benefi ts afforded by Tychoway Linear Roller Bearings meet the world s toughest recirculating Linear Roller Bearings provide predictable, repeatable positioning accuracy with minimum service requirements. A diverse range of sizes allows use in applications from compact dies to large machine tools. Tychoway Bearings have static load capacities rated from 4,330 to 122,000 lbs. The smallest bearing, only inches wide, can be mounted in very compact assemblies. Larger sizes are used in machine tools, paper machinery and other heavy equipment.

3 Made in the USA by skilled Ame-rican machinists Special Buna band gives con-tinuous guidance to the rollers, minimizing Roller skew Made of high-quality, high carbon alloy bearing steel Hardened to 60 Rockwell C mini-mum to insure high capacity and long life High race radius to Roller diame-ter ratio enhances Roller recir-culation and minimized friction, eliminating stick-slip forces Low friction rolling element design provides a system coeffi cient of friction of .005 or better for most applications Open load zone design provides space for contaminants to be forced away from the Roller path5RA 99 001 ( )TychowayBosch rexroth Corp. Linear Motion and Assembly TechnologiesApplicationsTychoway Linear Roller Bearings are used in a wide variety of applications. A choice of styles and sizes provide the special machine builder and OEM designer fl exibility in bearing selection.

Preloading permits low friction movement without looseness in the assem-bly.

5 The opposed Bearings can be mounted on Tychoway Spring Pads for a preset dynamic preload or on Tycho-Gibbs for maximum arrangement provides eco-nomical design where no uplift loads are present. It is used in a horizontal plane with gravity preload on the main load car-rying Bearings . A design popular in grinder and general purpose slides, the guide Bearings can be preloaded with a Tychoway Spring Pad or a Tycho-Gibbs for maximum bearing arrangement is ideal for vertical or horizontal rams, providing low friction motion with no looseness in the assembly.

The graph below indicates the effect of rail hardness on the load capacity of Tychoway Linear Roller and ground rails for assembly should be made with the working surface hardened to a minimum depth of .125 . Typical shapes and sizes of rails are shown at right. Special rails with key-ways and shoulders for more secure mounting are also common.
