Timken’s spherical plain bearings (SPBs), or bushings, are metal-on-metal bearings consisting of a spherically ground inner ring housed in a mating outer ring without any rolling elements. While all plain bearings are precision ground and made from through-hardened steel, custom orders are available and can include special materials, clearances, surface finishes or configurations to accommodate unique applications. Our SBT and SBDT designs feature lubricating holes and grooves in the outer ring for easy relubrication through the housing. Available in inch and metric sizes from 12.7 mm to 600 mm (.5 in. to 23.622 in.) bore Design Attributes Rings manufactured from hardened steel help deliver consistent, reliable performance. Phosphate-treated rings coated with molybdenum disulfide (MoS2) minimize friction of contacting surfaces. Simplified housing and shaft designs reduce installation time. Applications A-frames, dump cylinders, front and rear struts, and steering cylinders for mining trucks Equalizer track bars, lift and tilt cylinders, push blades, trunnion balls and ripper blades for bulldozers Articulated joint upper and lower steering cylinders and boom and bucket cylinders for wheel loaders Stick and bucket cylinders for hydraulic excavators Additional applications for space shuttles, heavy movable structures and miscellaneous vehicles

This series of plain bearings is similar to the SF and FS types, but also includes lip seals that are retained in the outer ring and withstand high grease pressures during lubrication. These lip seals assure full distribution of the lubricant to all bearing surfaces and protect against internal contamination. While all of our plain bearings are precision ground and made from through-hardened steel, custom orders are available and can include special materials, clearances, surface finishes or configurations to accommodate unique applications.

Timken® Split Cylindrical Roller Bearing Housed Units maximize uptime. They are easy to install and quick to maintain. When replacing trapped solid SN/SD/SAF housings, a split unit can reduce installation time up to 90%. The split-to-shaft feature makes installation and maintenance simple and fast. The SNQ / SAFQ pedestal type can further reduce downtime dramatically. It slides under the shaft eliminating the need to lift it and remove a drive to install a bearing. At home in a wide range of operating conditions, the 01 Light, 02 Medium and 03 Heavy Series handle increasingly higher static and dynamic loads. Pedestal, flange, hanger and tensioning support types are available. Catalog shaft size range: 35 mm to 600 mm, with custom units from 600 mm shaft size to 1500 mm O/D.

The Timken® ADAPT™ bearing combines the traditional cylindrical roller bearing and spherical roller bearing configurations. Its proprietary outer race and roller profiles plus a cylindrical inner ring combine the key attributes of both bearing types. This unique three-point contact design geometry provides simultaneous misalignment and axial displacement performance, optimizes contact stress distribution, and helps promote roller stability. The result is a more dynamic, more reliable bearing. Cross section illustration showing the design of the ADAPT bearing allows for simultaneous axial float and a misalignment capacity of 0.5 degrees. The rollers align with the inner ring regardless of axial displacement and misalignment. Key Benefits Proven Performance Timken conducted extensive in-house testing against equivalent-size toroidal bearings from leading brands. Results confirm ADAPT bearings offer: Infographic shows key benefits including higher load ratings up to 7%, lower operating temperatures of 5º-10ºc cooler, less running torque between 5-10% and longer service life up to 30%. Including 21 heat generation and bearing life tests conducted on 170 ADAPT and 50 competitor bearings; over 70,000 testing hours and over 8 years; bearings manufactured to ISO 2212 boundary dimensions (60 & 110 x 28 mm); speeds ranging from 1200 to 4800 RPM; loads between 10 and 50 percent of ISO calculated C1 rating. Easier Installation The ADAPT bearing consists of an inner ring, outer ring, and roller/retainer assembly. The separable components simplify installation, removal, and inspection. The retainer holds the rollers in position, creating a single assembly that prevents the rollers from being damaged during mounting and dismounting. The inner ring and outer ring can be installed in either direction, helping to avoid common mounting errors. No special tooling is required. ADAPT for Continuous Caster ApplicationsThree quarter angle view of the three main ADAPT bearing components on a white background – inner race, cage and rollers and the outer race. The metal industry’s tough environment places extreme demand on equipment. That makes maintaining operations and reducing downtime essential in continuous casters where performance and reliability are critical. ADAPT’s innovative design redefines the preferred choice of bearings for the float position in strand roll support segments.
