1 Timken Four-Row yldrical Roller ears
2 Timken four-row cyldrical roller bears are desed for the riors of daily use applications where moderate and hih speeds, hih radial loads, elevated temperatures and extreme debris are constant challenes. Desed with well-balanced cross sections, these bears provide hih radial load capacity with the bear envelope. Timken Four-Row yldrical Roller ears Applications Four-row cyldrical bears are eneered primarily for use roll mill roll-neck applications. These clude back-up, termediate and work roll positions flat product, lon product and structural mills. Product Features Available sizes 10 I.D O.D. ( ) ase-hardened rs and rollers enhance durability Inner races are terchaneable with outer assemblies Manufactured to P boundary tolerances and P runout standards Roller profiles are custom desed and manufactured for optimum performance Straiht and tapered bores are available Des enefits At your request, Timken can des and manufacture bears to fit your size and application requirements. Our eneers are ready to retrofit your exist mill or work with you the earliest des staes to select bears for a new mill. You also can choose from our most coon confiurations, types RY and RX. Inner rs can be provided a semifished condition with appropriate rd stock to allow mill operators to optimize the roll s precision by fish rd the ner r after mount it onto the roll. The part numbers for these bears and ner r assemblies are identified by a F suffix. Inner rs can also be provided a fished state with no additional rd required. They may be furnished with a tapered bore for your application. road le contact between the roll elements and races provide hih radial load capacity with the bear envelope. In addition, multiple cae dess and materials allow for des flexibility and preset radial clearance simplifies the stallation process. Type RY The RY des is available sizes up to 0 (1.91 ) bore and is primarily used work roll positions strip and lon product mills. Hih strenth brass caes are standard. Type RX The RX des is primarily used the back-up roll position and features a steel p-type cae which maximizes the number of rollers and the bear s radial capacity. It is available with either a straiht (RX) or tapered (RXK) bore. Note: Variations on the basic confiuration of the RY and RX bears are available to suit specific requirements. 2
3 A Total System Approach With more than 90 years of experience manufactur steel, we understand the challenes of metal production. Timken offers a complete le of products and services that help crease uptime, improve productivity and reduce matenance costs. Metal producers can choose from our full le of bears, seals, lubrication, condition monitor, tra, reliability services and more. Eneered Surfaces Timken eneered surfaces help protect bear components by imiz skidd and slid damae while withstand small particle contaation. In some cases, eneered solutions can extend bear life by up to three times that of standard dess. ear Remanufactur Timken s bear remanufactur proram provides customers with the best service options available, return bears to like-new specifications for less time and money than purchas new. When terated to youupply cha, remanufactur can extend bear service life and reduce your cost of operation.
