Product Description
Its suffix Z denotes a single metal shield on one side, which helps retain lubricant and keep contaminants out, making it suitable for ordinary industrial rotating machinery. The bearing uses a pressed steel cage with normal radial clearance and standard bearing steel, and it accommodates radial loads as well as moderate axial loads in both directions. The NSK 6005Z is a single-row deep groove ball bearing from the extra-light 6000 series, measuring 25 mm bore, 47 mm outside diameter and 12 mm width.
Basic Product Information
- 25 mm bore, 47 mm outside diameter and 12 mm width in the extra-light 6000 series
- Single metal shield (suffix Z) on one side to retain grease and reduce contamination ingress
- Pressed steel cage and NSK high-cleanliness bearing steel for long service life
- Low friction, quiet running and normal (CN) radial internal clearance
- Single-row deep groove design that carries radial loads and moderate axial loads in both directions
Technical Specifications
Version & Model Difference
The 6005 basic number shares the same 25 x 47 x 12 mm boundary dimensions across variants; the suffix defines sealing and clearance. The 6005 is open (no shield), the 6005Z has one metal shield (this model), the 6005ZZ has metal shields on both sides, and 6005-2RS / 6005DDU use rubber contact seals for harsher environments. C3 suffix versions offer increased radial clearance for higher-temperature or interference-fit duties.
Application Scenarios
- Electric motors, pumps, fans and small gearboxes
- Conveyors, blowers and general industrial transmission equipment
- Machine-tool spindles and auxiliary drives with moderate loads
- Household and commercial appliances and power tools requiring quiet, low-friction rotation

Frequently Asked Questions
What are the dimensions of the NSK 6005Z?
It has a 25 mm bore diameter, a 47 mm outside diameter and a 12 mm width.
What does the Z suffix mean?
The Z suffix indicates a single metal shield on one side of the bearing, which retains grease and blocks larger contaminants; the 6005ZZ has shields on both sides.
Is the 6005Z pre-lubricated?
Yes. The shielded design is normally supplied greased and the shield helps retain that lubricant over the service life, so no external grease line is required in most applications.
What load can the 6005Z carry?
The basic dynamic load rating is approximately 10.6 kN and the basic static load rating is 5.85 kN, with a limiting speed of about 18000 rpm under grease lubrication.
