Bearing Type
   Bearing Type       
   Your choices are...         
   Angular Contact, Single Row       These angular contact bearings have a single row of balls. Angular contact bearings form a contact angle between the races and balls when the bearing is in use. 
   Angular Contact, Double Row       Double-row, angular contact bearings have two rows of balls in a single inner and outer ring. 
   Flange Mounted Bearing       Flange mounted bearings are used when the shaft axis is perpendicular to the bearing mounting surface. They are available in 2, 3, or 4-hole configurations. 
   Hanger Bearing       Hanger bearings are rotational bearings for drive and screw conveyor shafts. They are enclosed in a housing or trough. 
   Linear Bearing       Linear bearings are used when a component needs to moved along a straight line with a high degree of accuracy. 
   Plain / Sleeve Bearing       Plain bearings and sleeve bearings are used to constrain, guide, or reduce friction. 
   Radial Ball Bearing, Single Row       These radial ball bearings have a single row of balls that rotate in a deep, machined groove in the inner and outer races. A cage maintains ball space. Single-row, radial ball bearings provide good radial load capacity, fair axial load capacity, and a limited ability to resist alignment. 
   Radial Ball Bearing, Double Row       These bearings are similar to single-row, radial ball bearings but have a second row of balls. Increasing the number of balls increases provides an increased ability to carry radial and thrust loads. Double-row bearings have the same radial mounting style as single-row bearings; however, their increased width reduces their ability to accommodate misalignment. 
   Roller Bearing, Cylindrical       Cylindrical roller bearings have high radial load capacity and moderate thrust loads.  They contain rollers that are “cylindrical” in shape.  The rollers are not true cylinders; they are crowned or end relieved to reduce stress concentrations.  This geometry translates to low friction and allows for high-speed applications.  Cylindrical roller bearings are commonly available in precision grades (RBEC-5).  Lubrication for cylindrical roller bearings is usually oil, which also serves as a coolant. 
   Roller Bearing, Spherical       Spherical roller bearings are self-aligning, double- row, combination, radial, and thrust bearings.  The rolling element is a spherical, or crowned, roller.  The outer ring has a spherical race that allows for some misalignment of the shaft and housing.  They are unequalled in their capacity for high loads and tolerance to shock loads, but have limited speed capabilities. 
   Pillow Block Bearing       Pillow block bearings are mounted bearings that provide load support for rotating shafts. The bearing housing mounts to a surface parallel to the shaft axis. 
   Slewing Ring / Turntable Bearing       These bearings can accommodate axial, radial and moment loads.  They are not mounted in housing or on a shaft, but instead are mounted directly to a seating surface.  The inner and outer rings are supplied with mounting holes.  The inner ring, outer ring, or both may have integral gears.  These bearings are referred to as tabletop bearings, turntable bearings, and slewing rings. 
   Takeup Bearing       Takeup bearings are primarily used to correctly tension conveyor belts and systems, or to align tracks.  They are available in three component types: bearing, frame, and take-up assembly (frame with bearing). 
   Tapered Roller Bearing       Tapered roller bearings consist of an inner ring (cone), an outer ring (cup), a cage and rollers that are profiled to distribute the load evenly across the roller. They have high radial and axial (thrust) load capacity at low to intermediate speeds.  The thrust load capacity for single row tapered bearings is about 60% of the radial capacity. Double row tapered roller bearings provide more load capacity than single row bearings.  They can also handle thrust loads from both directions. The rollers can be configured in a converging or a diverging orientation. In converging double row tapered bearings, the contact lines of the rollers to the races converge towards the axis of the bearing rotation. This style does not appreciably increase the rigidity of the shaft mounting.  In diverging double row tapered bearings, the contact lines of the rollers to the races diverge towards the axis of the bearing rotation. This style increases the rigidity of the shaft mounting.  Different configurations are available with a single outer ring and two inner rings or two outer rings and a single inner ring. Four row tapered bearings consist of four rows of alternating converging and diverging rollers. 
   Thin Section Bearing       Thin-section bearings have small cross-sections with respect to their diameter. 
   Thrust Bearing       Thrust bearings are designed for pure thrust loads and can handle little or no radial load. The rolling element in a thrust bearing can be a ball, needle or roller.

Dimensions
   Bore       The bearing industry uses a standard numbering system for bearings with metric-diameter bores. If the bore is hexagonal, enter the dimension across the flats.  If the bore is tapered, enter the smaller diameter. For bore sizes 04 and up, multiply the bore size by 5 to identify the bore diameter in millimeters (mm). Refer to the table below. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Outside Diameter / Length:       Enter the outside diameter of the bearing. For housed bearings, include the housing. For flanged bearings, exclude the flange. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Overall Width / Height:       Enter the overall width of the bearing or bearing assembly, including the locking collar (if present). 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Hex Bore?       Bearing has a hexagon shaped bore. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Tapered Bore?       Bearing has a tapered bore. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
