| 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. | ||||||||||||||||||||||||||||||||||||||||||||||

Ball Screw Support Bearing Types

| Ball Screw Support Bearing Types | |||
| 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. | ||
| One Directional Thrust Bearing | Bearing is one single directional thrust angular contact style bearing. Tolerates some misalignment. Same radial load as deep-groove bearings, but 2-3 times the thrust load. | ||
| Duplex Set | Two, matched bearings for use in ball screw support applications. | ||
| Triplex Set | Three, matched bearings for use in ball screw support applications. | ||
| Quadruplex Set | Four, matched bearings for use in ball screw support applications. | ||
| 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. | ||
| |||
| Cartridge Unit? | Ball screw support bearings are pre-assembled in a flanged cartridge unit. The cartridge typically consists of a housing with bolt holes parallel to the bearing axis, bearings and seals. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||
| |||
| Pillow Block Unit? | Ball screw support bearings are preassembled in a block or pillow block unit. The bearing assembly has a mounting surface perpendicular to the bearing axis and is assembled via predrilled bolt holes. The pillow block assembly typically includes seals. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||
| |||
| Combined Needle Roller | These bearings combine needle roller radial bearings with a ball or roller thrust bearing. These bearings can be used for combined radial and axial loading applications. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||

Special Material / Plating Options
Back to Top
|
|
| ||
| Your choices are... | |||
| Stainless Steel | Stainless steel is chemical and corrosion resistant and can have relatively high pressure ratings. | ||
| 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 and extended operating life. Bearings containing all ceramic balls are also nonconductive and are commonly used in electric motor applications. | ||
| Plated | Bearing is plated; common plating materials are cadmium and chrome. | ||
