6004-Z/C3MT Bearing Product Overview & Core Advantages
The 6004-Z/C3MT is a single row deep groove ball bearing designed for robust performance in demanding applications. Its core advantages stem from a shielded design and an optimized C3 radial internal clearance, making it an excellent choice for applications requiring reliable operation under moderate speeds and radial loads. The combination of high-grade chrome steel construction and precision ABEC 1 | ISO P0 tolerances ensures consistent performance and long service life, providing a cost-effective solution for a wide range of industrial machinery.
Model Code Breakdown
- 6004: Basic model number indicating a metric, single row deep groove ball bearing with a 20mm bore, 42mm OD, and 12mm width.
- Z: Signifies that one side of the bearing is equipped with a shield (non-contact). This provides effective protection against contamination while minimizing friction.
- C3: Denotes a greater than normal radial internal clearance. This is beneficial for applications involving thermal expansion, heavy loads, or where misalignment is a concern.
- MT: Indicates the bearing is pre-lubricated with a high-temperature, lithium-based grease. This provides immediate, maintenance-free operation right out of the box.
6004-Z/C3MT Bearing Structural Features & Performance Benefits
The bearing's performance is defined by its specific structural features:
- High Load Capacity & Rigidity: The single row deep groove raceway and chrome steel construction are engineered to handle significant radial loads (2113 lbf dynamic, 1135 lbf static), providing stable and rigid support for rotating shafts.
- Optimized for Moderate Speeds: With a limiting speed of 17,000 rpm, the bearing is suitable for a wide range of industrial applications. The shield (Z) helps retain lubricant and exclude contaminants, contributing to reliable high-speed operation.
- Enhanced Operational Reliability: The C3 clearance accommodates thermal expansion and slight misalignments, preventing premature failure. The pre-applied MT grease ensures immediate and effective lubrication, supporting operation within a temperature range of -30°C to 120°C.
- Low Maintenance & Longevity: The combination of the shielded design and pre-lubrication makes this bearing a virtually maintenance-free component, reducing downtime and total cost of ownership.
6004-Z/C3MT Bearing Typical Application Areas
The 6004-Z/C3MT is versatile and finds use in numerous sectors, including:
- Electric Motors and Gearboxes
- Industrial Pumps and Fans
- Material Handling Equipment (e.g., conveyor systems)
- Agricultural Machinery
- Automotive Components (e.g., alternators, idler pulleys)
