Index Page Conveyor Belt Storage and Installation Receiving the Roll Upon delivery check the factory packaging for damage punctures etc Make any appropriate claim against the carrier at that time Handling the Roll Factory packaging is designed to protect your conveyor belt during normal shipping and handling When a belt arrives be careful unloading it Don t drop it or handle it roughly This could break the packaging and cause the belt to telescope Once a belt tele scopes it is almost impossible to re roll Try not to roll it but if you must roll in the direction the belt is wound Rolling a belt in the opposite direction can cause it to loosen and telescope The best way to move a belt is to slip a sturdy hoisting bar through the center core Then lift it with a sling or with strong cables Be careful that these hoist cables don t damage the outer wraps at the belt edges Protect the edges with special spreader bars or short wooden planks Never apply a sling around the circumference of a roll of belting it isn t safe You can also move a belt safely by laying the roll flat on a skid and hoisting the skid with a forklift Just be sure the forks on the lift don t come in contact with the belt itself Storage When st

Paragraphs Before Establishing Lubrication Schedule Suggested Lubrication Period in Weeks OPERATING TEMPERATURE Abnormal bearing temperatures may indicate insufficient lubrication If the housing is too hot to touch for more than a few seconds check the temperature by applying a thermom eter at the top of the pillow block with the thermometer tip surrounded by putty Because the thermometer reading will be approximately 10 F lower than the actual bearing temperature add ten degrees to the reading and compare to the temperature rating of your grease If the bearing temperature reading is consistent and operating within the recommended limits of your grease the bearing is operating satisfactorily The recommended maximum operating temperature for S 2000 Spherical Roller Bearings is 200 F STORAGE OR SPECIAL SHUT DOWN If equipment will be idle for some time before shutting down add grease to the bearing until grease purges from the seals This will ensure protection of the bearing particularly when exposed to severe environmental conditions After storage or idle period add fresh grease to the bearing before starting SET SCREW TORQUE TABLE Socket Set Screw Tightening Shaft Size Size Torque 13 8 13 4 inches 5 16 inches 165 Inch Pounds 1115 16 27 16 inches 3 8 inches 290 Inch Pounds 1211 16 37 16 inches 1 2 inches 620 Inch Pounds 1315 16 415 16 inches 5 8 inches 1325 Inch Pounds RECOMMENDED SH

LT MOVES TOWARD THAT END OF THE ROLL IDLER IT CONTACTS FIRST The reader can demonstrate this for himself very simply by laying a small dowel rod or round pencil on a flat surface in a skewed orientation If a book is now laid across the dowel rod and gently pushed by one s finger in a line directly away from the experimenter the book will tend to shift to the left or right depending upon which end of that dowel rod the moving book contacts first BOOK MOVES LIKE SO Pulley Crown on Lightweight and Monofilament Belt A crowned pulley can be regarded as a special case of our primary rule of tracking as stated above The right half of the belt is contacting the center of the pulley sooner than it contacts the right edge of that pulley and therefore will tend to move toward the center The reverse is true of the left half of the belt The two forces tend to balance one another by centering the belt In addition to this surface effect however there is a strong internal balancing of warp tensions occurring Consider any warp yarn not directly on the center line If the belt is forced off center and this warp yarn is drawn toward the mid point of the crown tension will be increased on that yarn As the belt revolves and that yarn seeks to move back to its normal position this tension will dimin ish Yarns on both sides of the belt seek that posi tion which results in the least stress to themselves consistent

Roll 10 would now be functioning as the head pulley snubber Any adjustment off the perpendicular of roll 10 would have little tracking effect because there is no unsupported belt span between 11 and 10 Further such a deviation from the perpendicu lar would have a substantial cambering effect Under the circumstances therefore it should be set per pendicular to the belt center line Our comments relative to roll 9 through 5 inclu sive would be substantially the same as before Reaction of roll 4 however would reverse Pre viously it had a tracking effect and no cambering effect Now the reverse is true it has no tracking effect but considerable cambering effect Rolls 3 and 2 likewise have reversed their actions on the belt Accordingly all 3 of these rolls should be left perpendicular to the belt center line Roll 1 is now the tail pulley snubber rather than the head pulley snubber Here again it has reversed its role and will now exert a significant tracking effect and little cambering effect Roll 16 and roll 11 have now reversed positions and accordingly comments made previously about roll 11 would apply to roll 16 and vice versa Comments made previously on items 12 through 15 would essentially hold under these particular conditions It is of course recommended that rolls 11 13 14 15 and 16 simply set perpendicular to the belt cen ter line Finally if this particular conveyor were to be u
