6004ZZ Small Deep Groove Ball Bearings

6004ZZ Small deep groove ball bearings are standard industrial bearings designed for medium-size transmission equipment. The 6004ZZ features a double metal shield (ZZ) structure, pre-filled long-life grease, and maintenance-free operation for normal working conditions.
With a standard size of 20mm inner diameter × 42mm outer diameter × 12mm width, this bearing uses GCr15 high carbon chromium bearing steel with heat treatment for high hardness, wear resistance, and fatigue resistance.
The bearing adopts a high-strength stamped steel cage, providing stable operation and impact resistance. Standard precision is P0 industrial grade, with P6/P5 precision high-speed grades available for customization. These Small deep groove ball bearings provide smooth rotation, low friction, and stable performance for industrial equipment.

Product Applications
6004ZZ bearings are widely used in industrial transmission, mechanical equipment, and automation components, including:
● Industrial motor equipment
Small asynchronous motors, gear motors, variable frequency motors, fan motors, and water pump shafts.
● General mechanical equipment
Small conveyors, transmission rollers, production line equipment, packaging machines, and printing machine components.
● Fans and pumps
Industrial centrifugal fans, pipeline fans, booster pumps, and circulating water pump shafts.
● Electric tools
Medium grinders, cutting machines, grinding machines, and polishing equipment spindles.
● Commercial and household equipment
Large blenders, commercial hair dryers, industrial fans, and cleaning equipment motors.
● Automation and transmission parts
Instrument shafts, encoders, small automation mechanisms, industrial casters, and mechanical roller components.

Product Functions and Advantages
● Double ZZ metal shield for dust protection
The 6004ZZ uses double-side stamped steel shields that help prevent dust, particles, cotton fibers, and other contaminants from entering the bearing raceway. The strong shield structure is suitable for dry and dusty industrial environments.
● Standard deep groove structure with stable load performance
The deep groove ball design supports radial loads and light axial loads in both directions. The bearing provides smooth rotation, low friction, and stable performance during continuous operation.
● Durable GCr15 bearing steel construction
High-quality GCr15 steel with hardening and tempering treatment improves wear resistance, anti-fatigue performance, and service life compared with ordinary carbon steel bearings.
● Maintenance-free lubrication design
The bearing is pre-filled with long-life high-temperature grease. The sealed structure helps maintain lubrication and reduces maintenance frequency in normal dry conditions.
● Standard size and wide compatibility
The 6004ZZ is a standard bearing model with accurate dimensions, allowing direct replacement for many industrial equipment applications.
● Stable supply for bulk purchasing
Standardized mass production provides reliable supply, sufficient stock, and stable delivery for wholesale and long-term industrial customers.
