Bearing Design
   Thrust Bearing Type:       
   Your choices are...         
   Flat Race Thrust Ball       Flat race thrust bearings consist of a ball retainer held between two flat washers. They can tolerate rotational eccentricity, but not misalignment. These bearings are intended for pure thrust loading and are best suited to light loads. 
   Grooved Race Thrust Ball
Thrust Ball Bearing (drawing)Courtesy of CCVI USA
 
     Grooved race thrust bearings consist of a ball retainer held between two grooved washers. One washer is shaft-mounted and the other is bore-mounted. They have 2-4 times the thrust load and three times the rotational speed as flat race bearings, but can tolerate no misalignment or eccentricity. They are intended for pure thrust loads. 
   Two Directional Grooved Thrust       Two-directional grooved thrust bearings are back-to-back grooved race thrust bearings. They have two ball retainers and three grooved face washers. 
   Needle Roller Thrust
Needle Bearing (D) (drawing)Courtesy of CCVI USA
 
     Needle roller thrust bearings consist of a needle roller and cage assembly. They can be assembled against hardened flat surfaces or with hardened thrust washers. 
   Cylindrical Roller Thrust       Cylindrical roller thrust bearings consist of a roller and cage assembly. They can be assembled against hardened flat surfaces or with hardened thrust washers. They tolerate much higher loads than thrust needle roller assemblies. 
   Spherical Roller Thrust       Spherical roller thrust bearings have a spherical raceway in the outer ring. The rollers are arranged diagonally in single row. Spherical roller bearings have a high axial load capacity and can take moderate radial loads (when an axial load is applied). Due to the nature of the spherical rollers, they can handle some misalignment. 
   Tapered Roller Thrust       Tapered roller thrust bearings have conically-shaped (tapered) rollers and are designed for heavy axial load applications. Tapered roller thrust bearings are available with a cage or in a full complement design. 
   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. 
   Thrust Washer       Thrust washers are plain bearings with flat, parallel surfaces.  They work by means of sliding action as opposed to the rolling action used by ball, roller and needle bearings.  As in all bearings, proper lubrication is required to reduce wear and friction.  Some thrust washers are oil impregnated and do not require any additional lubrication. 
   Other       Unlisted, unspecified, or proprietary configuration. 
   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.

Special Material / Plating Options
   Bearing / Retainer Specialty Material       
   Your choices are...         
   Stainless Steel       Stainless steel is chemical and corrosion resistant and can have relatively high pressure ratings. 
   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. 
   Plated       Bearing is plated; common plating materials are cadmium and chrome. 
   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.
   Rolling Element Material:       
   Your choices are...         
   Glass         
   Polymer       A polymer is a solid, nonmetallic compound of high molecular weight, the structure of which is composed of small repeat units (mers). Plastics and elastomers are polymers. 
   Steel       Rolling elements are manufactured from steel. 
   Steel - Stainless       Stainless steel is chemical and corrosion resistant and can have relatively high pressure ratings. 
   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.
   Ceramic Balls       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. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   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. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
