Combination Roller Bearings FAQS

QWhat is Combined roller bearings?

ACombined roller bearings consist of a radial needle roller bearing combined with a thrust bearing. They can accommodate both radial and axial loads. They are particularly suitable for applications where other types of locating bearing arrangements occupy too much space, or where the axial loads are too heavy, the speeds are too high, or the lubricant is inadequate for arrangements with simple thrust washers.

QWhat is Needle roller thrust bearings?

ANeedle roller thrust bearings are fitted with a form-stable cage to reliably retain and guide a large number of needle rollers. Needle roller thrust bearings provide a high degree of stiffness within a minimum axial space. In applications where the faces of adjacent machine components can serve as raceways, needle roller thrust bearings take up no more space than a conventional thrust washer.

QWhat is spherical roller thrust bearing?

AA spherical roller thrust bearing is a rolling-element bearing of thrust type that permits rotation with low friction, and permits angular misalignment. The bearing is designed to take radial loads, and heavy axial loads in one direction. Typically these bearings support a rotating shaft in the bore of the shaft washer that may be misaligned in respect to the housing washer. The misalignment is possible due to the spherical internal shape of the house washer.

QWhat is Cross Cylindrical Roller Bearings?

AThe Cross Cylindrical Roller Bearings include the type with cage, type with separator and full complement type. The type with cage and the type with separator have a small coefficient of friction and are suitable for comparatively high speed rotations, while the full complement type is suitable for heavy load applications at low speed rotations.

QWhat is Journal Roller Bearings?

AJournal Roller Bearings are designed for moderate to heavy radial loads and carry the designation of a 3-piece separable bearing. An Inner Race, Outer Race, and Roller Assembly make up the complete bearing. They are made in Metric and Inch series and designed with special widths, oil holes, or key notches for specific industries. Components have been designed to interchange with other manufacturers. These bearings have been popular for many years and have been incorporated into many OEM applications. Their use in corrugating machinery, line shafts, table rolls, forging equipment, and general industry applications make them very popular in the replacement market.

QWhat is cylindrical roller thrust bearing?

AA cylindrical roller thrust bearing is a particular type of roller bearing. Like other roller bearings, they permit rotation between parts, but they are designed to support a high axial load while doing this (parallel to the shaft). Higher speed applications require oil lubrication.Generally, they are composed of two washers (raceways) and the cylindrical roller elements which are typically caged. As opposed to roller thrust bearings, ball thrust bearings can generally operate at higher speeds but at lower loads.Cylindrical roller thrust bearings are designed to accommodate heavy axial loads and impact loads. They must not be subjected to any radial load. The bearings are very stiff and require little axial space.
