The 6216 is a standard bearing in the CXJSD 6200 series, featuring an 80 mm bore, 140 mm outside diameter, and 26 mm width. It has a basic dynamic load rating of 72.5 kN and a basic static load rating of 53.0 kN, with 11 balls measuring 18.256 mm in diameter. The 6216 bearing has a grease lubrication speed of 4,500 r/min and an oil lubrication speed of 6,300 r/min, with an approximate weight of 1.40 kg per piece. CXJSD supplies 6216 deep groove ball bearings in open, ZZ, 2RZ, and 2RS configurations.

The 6216 deep groove ball bearing uses four primary components: an inner ring, outer ring, steel balls and a cage. Together, these components support the rotating shaft and guide the rolling elements during operation.

The inner ring has an 80 mm bore and provides the mounting surface for the rotating shaft while forming the inner raceway for the steel balls.
The outer ring has a 140 mm outside diameter and provides the outer raceway that guides the steel balls during bearing operation.
The 6216 uses 10 steel balls with a diameter of 19.05 mm, which roll between the inner and outer raceways to reduce friction and transmit loads.
The cage keeps the steel balls evenly spaced and guides their movement between the inner and outer rings during rotation.
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.
The 6216 is used in rotating equipment where its deep groove design can support radial loads and axial loads in both directions, including industrial machinery, pumps, agricultural equipment, conveyors and textile machinery.
The 6216 deep groove ball bearing supports rotating shafts in industrial motors and electrical machinery while accommodating radial loads and axial loads in both directions.
In pumps and compressors, the 6216 supports rotating shafts and helps maintain smooth operation under continuous radial and axial loading.
The 6216 is used in agricultural machinery such as tractors and other equipment to support rotating components operating under continuous mechanical loads.
In conveyor and material handling systems, the 6216 supports rotating shafts and components exposed to continuous radial loads during material transport.
The 6216 helps support rotating components in textile machinery while providing low-friction operation for continuous production processes.

Answers to common questions about 6216 bearing dimensions, load capacity, clearance, sealing options and speed.
The standard 6216 bearing measures 80 mm bore, 140 mm outside diameter, and 26 mm width. These dimensions should be confirmed before ordering a replacement.

For the standard NSK 6216, the basic dynamic load rating is 80 kN and the basic static load rating is 53 kN; actual allowable loads depend on speed, installation, lubrication, and operating conditions.

The main difference is radial internal clearance: C2 provides less clearance than normal, while C3 provides more clearance, so the correct version depends on the shaft fit, temperature, speed, and operating conditions.

An open 6216 has no integral shield or seal, ZZ uses metal shields for contamination protection, and 2RS uses rubber seals for stronger protection against dust and moisture; sealing can also affect speed.

Speed depends on the manufacturer and configuration; for example, NSK lists 5,300 r/min with grease and 6,300 r/min with oil-bath lubrication for its standard 6216, so the exact product data should be checked before high-speed operation.
