5 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 2 on page 9 for suggested shaft 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 bolt the housing tightly to its mounting supports using an appropriately sized fastener and suggested bolt torque (table 4 on page 9). 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 3 on page 9). ball BeARinG HOUSeD UniTS are available in a wide variety of sizes and housing styles to accommodate a complete range of operating UniTS generally have cast-iron housings and are designed for mounting on straight shafts with a slip fit.

6 The set screw locking mechanism provides ease in 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 RELubRICatIon SuggEStIonS FoR gREaSED bEaRIngS (1)(1)As a guideline, relubricate until the first indication of grease is observed purging from the INTERVALI ndoor serviceOutdoor serviceSevere outdoor exposureHigh contamination/washdownNot requiredTwo/three times per yearOnce a monthOnce a weekfor additional Timken product warnings, visit Failure to observe the following warnings could create a risk of death or serious maintenance and handling practices are critical. Always follow installation instructions and maintain proper 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.

7 Consult your equipment designer or supplier for installation and maintenance not use excessive force when mounting or dismounting the all tolerance, fit and torque follow the Original Equipment Manufacturer s installation and maintenance proper weld HOUSeD not heat components with an open not operate at BeARinG temperatures above 121 C (250 F).warning Failure to follow these cautions may result in property hammer and bar are used for installation or removal of a part, use a mild steel bar ( , 1010 or 1020 grade). Mild steel bars are less likely to cause release of high-speed fragments from the hammer or bar or the part being installed or not use damaged HOUSeD following tables provide useful installation details related to shaft tolerance and torque for set screws and bolts.
