Ball bearing No name 6005 ZZ — single-row deep groove, metal shields (ZZ)

Single-row deep-groove ball bearing No name 6005 ZZ features a hardened steel inner and outer ring, a single row of balls and metal shields on both sides (ZZ). The design provides reliable radial load support and allows limited axial loads in both directions while reducing friction in rotating assemblies. With metal shields fitted to both faces, the bearing offers protection against moderate contamination and retains lubricant, making it suitable as a replacement component in electric motors, gearboxes, pumps and conveyor rollers.

Advantages

The metal shields on both sides reduce ingress of dust and splash while retaining lubricant, extending service intervals under moderate contamination. The deep-groove geometry permits smooth high-speed rotation with low noise and vibration. A compact single-row layout ensures simple mounting in standard housings and shafts, and the hardened rings and balls provide long term wear resistance when installed and lubricated correctly.

Suitable for

• Electric motors and fans
• Gearboxes and transmission assemblies
• Pumps and compressors
• Conveyor rollers and material handling equipment
• General industrial and automotive rotating components

Key specifications

• Bearing type: single-row deep-groove ball bearing
• Shielding: metal shields on both sides (ZZ)
• Load direction: primarily radial, limited axial load capacity in both directions
• Construction: hardened steel rings and balls
• Lubrication retention: shields help retain grease for extended intervals
• Typical applications: medium-speed rotating assemblies

How to use

Install the bearing by aligning the inner ring with the shaft and pressing or sliding it into position using a suitable tool that applies force to the inner ring only. Avoid applying pressure to the outer ring to prevent raceway damage. Ensure mating fits (shaft and housing) match recommended tolerances for interference or transition fits as appropriate for the application. Clean contacting surfaces and apply the manufacturer-recommended grease if additional lubrication is required; sealed/shielded bearings are often pre-lubricated but may need topping up in service. After installation, check for smooth rotation and correct axial positioning before placing the assembly into operation.

Usage recommendations

For reliable service, use a compatible high-quality grease and maintain regular inspection intervals for temperature, noise and vibration. Replace the bearing if excessive play, roughness, elevated operating temperature or contamination is observed. When selecting this bearing, verify dimensional compatibility with the mating shaft and housing and consider operating speed and load to ensure expected life.
