The 6215 is a 6200-series deep groove ball bearing with a 75 × 130 × 25 mm standard size. Its single-row design uses an inner ring, outer ring, steel balls and a cage to support radial loads and axial loads in both directions. It is suitable for motors, pumps, fans, conveyors, agricultural machinery and other general-purpose rotating equipment.
The 6215 deep groove ball bearing is a standard 6200-series bearing designed for applications requiring a larger bore and higher load capacity while maintaining the compact single-row deep groove design. The following specifications are based on the CXJSD 6215 configuration.

The 6215 deep groove ball bearing uses four primary components: an outer ring, steel balls, a cage and an inner ring. Together, these components provide smooth rotation, low friction and reliable support for rotating shafts.

Provides the outer raceway that guides and supports the steel balls during rotation and fits into the bearing housing.
The 11 steel balls transfer loads between the inner and outer rings while reducing friction during rotation.
Keeps the steel balls evenly spaced and guides them smoothly around the bearing during operation.
Provides the inner raceway for the steel balls and mounts onto the 75 mm shaft.
Has no shields or seals, providing low running resistance and allowing external lubrication where the application requires it.
Two metal shields help retain factory grease and reduce the entry of dust and coarse contaminants with relatively low added friction.
Two rubber seals provide stronger protection against moisture and fine contaminants and are suitable for more demanding operating environments.
With a 75 × 130 × 25 mm size, substantial load ratings and a single-row deep groove design, the 6215 is suitable for general industrial rotating equipment where a larger bearing size is required.
Supports larger motor and generator shafts while providing smooth rotation and reliable radial load support.
Supports rotating shafts and impellers while handling radial and bidirectional axial loads in continuous-duty equipment.
Supports larger fan shafts and rotating components in ventilation and industrial air-moving equipment.
Supports conveyor rollers and rotating shafts in material-handling systems requiring a larger standard bearing.
Supports rotating components in tractors, irrigation equipment and other agricultural machinery.
The feedback below is illustrative website content showing common purchasing considerations for 6215 bearings. It is not presented as verified customer testimony.
We were looking for a larger standard bearing for rotating industrial equipment. The 6215 size matched our shaft and housing requirements, and the main concern was consistent dimensional quality for replacement orders.
The 75 × 130 × 25 mm dimensions made it straightforward to match this bearing with the existing equipment. We mainly needed a standard replacement with the correct sealing option.
For distribution orders, having the standard 6215 dimensions and load ratings clearly specified makes it easier to cross-check customer replacement requirements before quoting.
We needed a 75 mm bore bearing for rotating pump equipment. The 6215 specification gave us a clear reference for checking the shaft size, housing fit and available installation space.
For regular inventory planning, the standard 6215 dimensions and multiple sealing configurations make it easier to match replacement requirements across different types of industrial equipment.

Answers to common questions about 6215 bearing dimensions, sealing options, load capacity, speed and applications.
The 6215 is a single-row deep groove ball bearing in the 6200 series. Its standard dimensions are 75 mm bore, 130 mm outside diameter and 25 mm width. It is designed primarily for radial loads and can also accommodate axial loads in both directions.

The standard 6215 bearing dimensions are 75 mm bore × 130 mm outside diameter × 25 mm width. The minimum chamfer is 1.5 mm. Buyers should confirm the shaft diameter, housing bore and available bearing width before ordering replacement bearings.

The basic bearing dimensions are the same, but the sealing configuration is different. A 6215-2RS uses two rubber seals for stronger protection against dust and moisture, while a 6215-ZZ uses two metal shields and generally provides lower sealing resistance. An open 6215 has no seals or shields.

CXJSD lists the 6215 with a dynamic load rating of 66.0 kN and a static load rating of 49.5 kN. Actual bearing life and load capacity depend on the operating load, speed, lubrication, installation and application conditions.
_1789089904_WNo_900d429.jpg)
CXJSD lists the standard 6215 with a grease lubrication speed rating of 4,800 r/min and an oil lubrication speed rating of 5,600 r/min. Actual allowable speed also depends on seal type, lubrication, operating temperature, clearance and application conditions.
