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

| Static Radial Load | Static radial load is the maximum radial load a bearing can endure without excessive, permanent deformation. | ||
| 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. | ||
| |||
| Moment Load | Enter the maximum moment load for the application. | ||
| 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. | ||

Slewing Ring / Turntable Bearing Type
Back to Top
|
|
| ||
| Slewing Ring / Turntable Bearing Type: | |||
| Your choices are... | |||
| Single Row Ball | Single row of balls with standard bearing raceway. | ||
| Four Point Contact | Single-row ball bearing with four-point contact between balls and raceways. | ||
| Eight Point Contact | Double-row ball bearing that has eight-point contact points between adjacent balls and raceways, four contact points to each ball. | ||
| Inserted Raceway | Rolling element (ball or roller) contacts an inserted raceway, typically made of wire, that creates a robust but lightweight assembly. | ||
| Two Row Roller | Two independent rows of rollers constrain the motion. | ||
| Three Row Roller | Three independent rows of rollers constrain the motion. | ||
| Cross Roller | Single-row of rollers with the axes of alternating adjacent rollers at right angles to one another. | ||
| Single Row Ball and Single Row Roller | Incorporates a single row of balls and a single row of rollers for small radial runout and high thrust loads. | ||
| 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. | ||

| Gear Options: | |||
| Your choices are... | |||
| Non-geared | Bearing has no integral gears. | ||
| Internal Gear Only | Bearing has an integral gear on the bore (inner ring). | ||
| External Gear Only | Bearing has an integral gear on the outside diameter (outer ring). | ||
| Internal and External Gears | Bearing has an internal gear on the bore (inner ring) and an external gear on the outside diameter (outer ring). | ||
| 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. | ||
| |||
| Flanged | The bearing has a flange for mounting or locating. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||
