Machined Outer Race
Race manufactured from bearing quality steel and hardened to carry heavy dynamic and static loads.
Needle Rollers with End Relief (Most Sizes)
Precision Needle Rollers provide high radial load capabilities in small radial envelope dimension. End relief features help reduce raceway stress when shaft misalignment occurs.
Steel Cage
Welded construction minimizes roller radial play for ease of assembly and provides roller guidance helping to reduce friction. The spacing provided by the retainer contributes to the high speed capabilities and lubricant reservoir within the bearing envelope.
Annular Lubrication Groove
The groove provides a circumferential path to direct lubricant to the hole when lubricating through the housing.
Factory Grease Fill
The Sealed CAGEROL bearings are factory lubricated with a medium temperature (-30° to 250°F, -34° to 121°C) NLGI 1 grease, unsealed bearings packaged with light oil film as a rust preventative. Contact Application Engineering when application conditions require special lubricants.
Seals
The rubber lip seal is capable of 250°F maximum temperature and is available in several different configurations.
"DS" Matched Bearings - Load Sharing
When two bearings are installed with the distance between both bearing less than the width of one bearing, it is recommended the bearings be diametrically matched to prevent unequal load sharing. The option, when applicable matches OD and ID tolerances, diametrical clearance within 30% of the tolerance range and the radial runout within 20% of the tolerance range with high point of runout indicated on the bearing faces. For more information and matching factors please review the engineering section for matched bearings. Matched bearings packaged as sets.
Machined Inner Ring(MI)
Precision ground inner ring provides a hardened raceway for the rollers when used with an unhardended shaft. The ring contains an oil hole and annular groove relubrication of the bearing and can be used with both CAGEROL and GUIDEROL bearings or can be utilized as a bushing in plain bearing applications.
Grease Options
When requested, standard bearings can be factory filled with customer specified lubricant.
