| Rolling Element Type | |||
| Your choices are... | |||
| Balls | The rolling and load-bearing elements of the bearing are spherical in shape. A cage may be used to separate rolling elements from colliding in the raceways. | ||
| Rollers | The rolling and load-bearing elements of the bearing are cylindrical in shape. A cage may be used to separate rolling elements from colliding in the raceways. | ||

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 | 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. | ||
| |||
| Outer Ring Width: | The width of the outer ring. | ||
| 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. | ||

Operating Specifications
Do not over-specify. Enter only those loads that apply for bearing type and application. Static and dynamic loads may not be available for all bearing types and suppliers.

| Dynamic Radial Load | Dynamic radial load is the calculated, constant, radial load which a group of identical bearings can endure theoretically for a rating life of one million revolutions of the inner ring. | ||
| 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. | ||

Seals / Shielding
Back to Top
|
|
| ||
| Seals / Shielding: | Seals and shields provide protection from contamination and as a retainer for lubricant. Seals provide better protection and lubricant containment than shields, but have lower maximum speed capabilities. | ||
| Your choices are... | |||
| None (Open Bearing) | Bearing is open; it has no seals or shields. Open bearings offer no protection from contamination or lubricant containment, but have higher maximum speed capabilities than bearings with seals or shields. | ||
