6203-Z/CNHMT Bearing Product Overview & Core Advantages
The 6203-Z/CNHMT is a metric single row deep groove ball bearing engineered for reliable performance in a wide range of industrial applications. Its core advantage lies in its ability to efficiently support radial loads while offering robust operation. The inclusion of a shielded design (Z) provides effective protection against contaminant ingress, enhancing service life. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing delivers consistent precision and is an excellent choice for applications demanding high reliability and compact design.
6203-Z/CNHMT Bearing Model Code Explained, Specifications & Naming Convention
- 6203: Basic model number denoting a medium-duty, single row deep groove ball bearing with a 17mm bore, 40mm OD, and 12mm width.
- -Z: Signifies that the bearing is equipped with a non-contact shield on one side. This provides protection from large particulate contaminants while minimizing friction and heat generation.
- /CN: Indicates the standard radial internal clearance group (Normal clearance) for general application use.
- HMT: This suffix combination signifies the material specification. H denotes the use of Chrome Steel for rings, balls, and cage, ensuring high strength and durability.
6203-Z/CNHMT Bearing Structural Features & Performance Benefits
The performance of the 6203-Z/CNHMT is derived from its fundamental design and material selection. The deep groove raceway and optimized geometry enable it to handle significant radial dynamic load ratings (2147 lbf). The use of a stamped steel cage ensures reliable ball guidance and is suitable for the bearing's limiting speed of 17,000 rpm. The shielded (Z) construction is a key feature, offering a balance between contamination protection and low running torque. Manufactured entirely from Chrome Steel, the bearing provides excellent wear resistance and a long operational lifespan within its specified temperature range of -30°C to 120°C.
6203-Z/CNHMT Bearing Typical Application Areas
This versatile bearing is commonly specified in a variety of sectors and equipment, including:
- Electric Motors and small gearboxes
- Industrial Fans and blowers
- Conveyor system idler rollers
- Agricultural machinery
- Automotive components (e.g., alternators, water pumps)
- General machinery requiring a reliable, shielded ball bearing
