Features:

Bearing Configurations
Separable or Non-separable Inner/Outer Raceway

Shaft Diameter Range
½" to 9¼" and 15mm to 235mm

Materials
Bearing Quality Steel

Benefits:

Machined Outer Race
Race manufactured from bearing quality steel and hardened to carry heavy dynamic and static loads.

Unique Center Guided Needle Rollers
Centered guided rollers are designed to fit a mating guide rail. They also allow for a maximum width of roller within the bearing.

Retaining Ring and Center Rail
Provides retention of needle rollers and helps guide rollers to prevent skewing.

Annular Lubrication Groove
The groove provides a circumferential path to direct lubricant to the oil hole when lubricating through the housing.

Factory Grease Fill

Sealed GUIDEROL^® bearings are factory lubricated with a medium temperature (-30° to 250°F, -34° to 121C) NLGI 1 grease. Unsealed bearings are packaged with a light oil film as a rust preventative. Contact Application Engineering when application conditions require special lubricants.

Seals
The rubber lip seal is available in several different configurations. It is capable of operating at up to 250°F maximum temperature.

"DS" Matched Bearings - Load Sharing
Where two bearings are installed, load sharing should be encouraged when the distance between is less than the width of one bearing. To accomplish this, it is recommended that the bearings be diametrically matched. The option, when applicable, matches OD and ID tolerances. It also maintains diametrical clearance within 30% of the tolerance range and the radial runout within 20% of the tolerance range. The high point of runout is 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)
The precision ground inner ring provides a hardened raceway for the rollers when used with an unhardened shaft. The ring contains an oil hole and annular groove relubrication of the bearing. It can be used with both CAGEROL^® and GUIDEROL^® bearings. It can also be utilized as a bushing in plain bearing applications.

Grease Options
When requested, standard bearings can be factory filled with customer specified lubricant.
