TIMKEN BALL BEARING HOUSED UNITS DESIGNED FOR OPTIMIZED PERFORMANCE For more than 0 years, Timken innovations continue to keep the world in motion, including the invention of the wide inner ring bearing and the ball bearing housed unit. We continue that innovation by applying our extensive engineering knowledge of bearings, metallurgy, seals and end-user applications to deliver optimized performance from our housed unit product line. Timken ball bearing housed units help improve efficiencies through: INCREASED EQUIPMENT UPTIME AND REDUCED MAINTENANCE COST Bearings with spherical outer rings and precision-machined cast-iron housings help prevent outer ring rotation. Bearings withstand static misalignment of the shaft of +/ 3 degrees. Designed for normal operation between 20 C and 00 C. Wide inner ring ball bearings deliver greater shaft support. High-strength housings are suited for most industrial applications. Bearings are prelubricated and ready for iediate installation. Timken knowledge and support come standard. ROBUST SEALING DESIGNED FOR THE MOST DEMANDING ENVIRONMENTS Precision sealing provides extended bearing life and reduced lubrication leakage. Bonded seal design includes a steel flinger for additional bearing protection. Effective grease retention and reduced debris and moisture ingress improve bearing performance. WIDE RANGE OF READY-TO-MOUNT UNITS Five different housing designs plus replacement inserts are offered in metric and imperial sizes. Set screw locking design allows for easy installation. Extensive range of sizes meets the needs of a wide range of applications. Interchangeable without modification in many applications. Local in-stock availability ensures the service levels you expect. Timken supports your job sites with a team of service engineers available around the world. Their services help extend maintenance cycles and maximize uptime. Timken is your single-source for friction management, with a full range of bearings and related accessories including greases, seals, tools, training, repair service. 3

FEATURES Precision formed flinger Provides the first level of protection against contamination. High-performance seal Bonded nitrile rubber seal with an engineered interface to the inner ring. Hardened and ground seal land Helps protect against abrasive wear, extending seal life. Outer ring with spherical outside diameter Engineered fit between bearing and housing to improve bearing life. Lubrication delivery system Precision-machined lubrication groove and holes in the outer ring of the bearing. Engineered balls and cage Steel cage provides effective ball guidance and high temperature service capability. Wide inner ring Improved shaft support over narrow rings, improving bearing life and reducing misalignment. Set screw angle 20-degree angle minimizes inner ring distortion for smoother-running bearing. Cast-iron housing Incorporates ISO 85 Grade 200 (ASTM A48 Class No. 30) cast iron. Premium grease Prelubricated with high-quality lithium-based grease, compatible with most industrial greases. Lubrication hole Precision formed flinger High-performance seal Engineered balls and cage Outer ring with spherical outside diameter Lubrication groove Wide inner ring 4 Hexagon socket set screw Housing (pillow block)

INSTALLATION Ball bearing housed units are available in a wide variety of sizes and housing styles to accoodate a complete range of operating conditions. These cast-iron housings are designed for mounting on straight shafts with a slip fit. The set screw locking mechanism provides ease in mounting.. Ensure that the shaft is clean, free from burrs, straight and of proper diameter. The bearing should not be mounted on a worn section of the shaft. Using shafts with hardness greater than HRC 45 will reduce effectiveness of locking devices. See table on page 7 for suggested shaft tolerances. Grease fitting in lubrication hole 2. Install the supplied grease fitting into the threaded lubrication hole on the housing. Align the bearing in its housing and slide the unit into position on the shaft. 3. Bolt the housing tightly to its mounting supports using an appropriately sized fastener and suggested bolt torque (table 3 on page 7). Flat washers should be used when installing any kind of housed unit. Washers should be properly sized to bolt diameter. 4. Lock the bearing to the shaft by tightening each inner ring set screw incrementally to suggested torque levels (table 2 on page 7). WARNING Failure to observe the following warnings could create a risk of death or serious injury. Proper maintenance and handling practices are critical. Always follow installation instructions and maintain proper lubrication. Overheated bearings can ignite explosive atmospheres. Special care must be taken to properly select, install, maintain and lubricate housed unit bearings that are used in or near atmospheres that may contain explosive levels of combustible gases or accumulations of dust such as grain, coal, or other combustible materials. Consult your equipment designer or supplier for installation and maintenance instructions. Do not use excessive force when mounting or dismounting the unit. Follow all tolerance, fit and torque recoendations. Always follow the Original Equipment Manufacturer s installation and maintenance guidelines. Ensure proper alignment. Never weld housed units. Do not heat components with an open flame. Do not operate at bearing temperatures above 2 C (250 F). CAUTION Failure to follow these cautions may result in property damage. If haer and bar are used for installation or removal of a part, use a mild steel bar (e.g., 00 or 020 grade). Mild steel bars are less likely to cause release of high-speed fragments from the haer or bar or the part being installed or removed. Do not use damaged housed units. FOR ADDITIONAL TIMKEN PRODUCT WARNINGS, VISIT WWW.TIMKEN.COM/WARNINGS. RELUBRICATION Timken ball bearing housed units are prelubricated. However, periodic relubrication is advisable in some applications for which these units are designed. Consult your equipment manufacturer s operating manual for the specific relubrication cycle. General guidelines are found in table 4. GENERAL RELUBRICATION SUGGESTIONS FOR GREASED BEARINGS () TABLE 4 CONDITION RELUBRICATION INTERVAL Indoor service Outdoor service Severe outdoor exposure High contamination/washdown Not required Two/three times per year Once a month Once a week () As a guideline, relubricate until the first indication of grease is observed purging from the bearing. 4
