NSK BK2016 Closed-End Needle Roller Bearing – 20 × 26 × 16mm | Heavy Duty Industrial Bearing
NSK BK2016 Closed-End Needle Roller Bearing – 20 × 26 × 16mm | Heavy Duty Industrial Bearing
Product Description
The BK2016 Closed-End Needle Roller Bearing is a high-quality, compact industrial bearing designed to provide excellent radial load capacity, smooth rotation and reliable performance in demanding mechanical applications.
Featuring a precision-engineered drawn steel outer cup, cylindrical needle rollers and a closed-end construction, the BK2016 offers high load-carrying capability while maintaining a compact, space-saving design.
Its closed-end structure makes this bearing particularly suitable for blind housing installations, where a rotating shaft requires radial support near its end.
With a 20mm roller-inscribed diameter, 26mm outside diameter and 16mm overall width, the BK2016 is suitable for industrial machinery, gearboxes, conveyor systems, CNC equipment, agricultural machinery, industrial automation and mechanical drive assemblies.

Benefits of Closed-End Needle Roller Bearings
Closed-end needle roller bearings are designed to provide high radial load capacity in compact applications.
Their thin-walled drawn steel outer cup reduces installation space requirements, while precision needle rollers distribute radial loads efficiently.
Main advantages include:
-
High radial load capacity relative to bearing size
-
Compact and lightweight construction
-
Suitable for blind housing installations
-
Closed end helps reduce contamination entering from one side
-
Smooth and efficient rotation with suitable lubrication
-
Efficient use of limited installation space
-
Reliable performance in industrial mechanical assemblies
-
Convenient installation into compatible housings
Installation and Maintenance Recommendations
-
Verify shaft diameter, housing bore and bearing dimensions before installation.
-
Ensure the housing is clean, correctly machined and free from damage.
-
Use an appropriate bearing installation mandrel to press the bearing into the housing.
-
Avoid applying installation forces directly through the needle rollers.
-
Ensure the shaft running surface is correctly hardened, ground and finished.
-
Apply suitable grease or oil according to operating conditions.
-
Avoid excessive misalignment, contamination and improper loading.
-
Inspect the bearing periodically for wear, overheating, vibration and unusual noise.
