Bearing Type
   Bearing Type:       
   Your choices are...         
   Radial Ball Bearing       Radial, or deep groove bearings, can take radial and axial loads to varying degrees but are used when the primary load is in the radial direction. They consist of an inner ring, an outer ring, balls, and sometimes a cage to contain and separate the balls. 
   Angular Contact Ball Bearing       Angular contact bearings are designed such that a contact angle between the races and the balls is formed when the bearing is in use. The major design characteristic of this type of bearing is that one or both of the ring races have one shoulder higher than the other. In order for these bearings to function properly, they must be assembled with a thrust load. This loading (or preload) creates a line of contact (or contact angle) between the inner race, the ball, and the outer race. The preload can be built in to the bearing or created when the bearing is inserted into an assembly. The contact angle varies from 15° to 40° and is measured relative to a line running perpendicular to the bearing axis. Angular contact bearings are one-directional thrust bearings that can withstand heavy thrust loads and moderate radial loads. 
   Roller Bearing         
   Thrust Bearing       Thrust ball bearings are designed for pure thrust loads. These bearings can handle little or no radial loads. The rolling element can be a ball, needle, or roller.

Bore Diameter
   Bore Size       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.

Special Material / Plating Options
   Stainless Steel       Stainless steel is chemical and corrosion resistant and can have relatively high pressure ratings. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Plastic       Any of numerous organic, synthetic, or processed materials that are mostly thermoplastic or thermosetting polymers of high molecular weight and that can be made into objects, films, or filaments. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Ceramic Races       Bearing races are constructed of ceramic (typically Si3N4). 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Plated       Bearing is plated; common plating materials are cadmium and chrome. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Rolling Element Material:       
   Your choices are...         
   Ceramic       A ceramic hybrid bearing is constructed of steel inner and outer rings with ceramic (typically Si3N4 balls in place of steel. These bearings have several advantages over all steel bearings, such as higher speed and acceleration capability, increased stiffness, higher accuracy, lower friction and heat generation, reduced lubrication requirements, low thermal expansion, extended operating life. Bearings containing all ceramic balls are also nonconductive and are commonly used in electric motor applications. 
   Ceramic / Steel Ball Combination       Fifty percent of the balls in the bearing are manufactured from ceramic and fifty percent from steel. This bearing has most of the characteristics of a bearing with all ceramic balls but is significantly less expensive. 
   Stainless Steel       Stainless steel is chemical and corrosion resistant and can have relatively high pressure ratings. 
   Steel       Rolling elements are manufactured from steel. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
