Product detailed description
Bearing 6011 C3 ZKL
The 6011 C3 ZKL is a high-quality deep groove ball bearing designed for reliable and efficient performance in a wide range of mechanical applications. Manufactured by ZKL, a reputable brand known for precision and durability, this bearing is engineered to provide smooth rotational movement and withstand moderate radial and axial loads.
This particular model, 6011 C3, features a C3 internal clearance, which means it has a greater than normal clearance between the bearing’s inner and outer rings. This makes it especially suitable for applications where thermal expansion or high speeds are expected, ensuring optimal performance without compromising bearing life.
The "Z" in the designation indicates that the bearing is equipped with a single metal shield on one side. This shield protects the bearing from dust and debris while allowing for lubrication maintenance, making it ideal for environments where moderate contamination is present but full sealing is not required.
Dimensions of the 6011 C3 ZKL bearing are standardized, with an inner diameter of 55 mm, an outer diameter of 100 mm, and a width of 21 mm. These dimensions comply with ISO standards for 6011 series bearings, ensuring compatibility with a broad range of machinery and equipment.
Key Features and Benefits
- High Precision: Manufactured to tight tolerances for smooth and quiet operation.
- C3 Clearance: Provides extra internal clearance for applications involving higher speeds or temperature variations.
- Metal Shield (Z): Offers protection against dust and particles while facilitating lubrication.
- Durable Construction: Made from high-grade steel to resist wear, corrosion, and fatigue.
- Versatile Use: Suitable for electric motors, pumps, gearboxes, and general industrial machinery.
Applications
The 6011 C3 ZKL bearing is widely used in various industries due to its robust design and reliable performance. Typical applications include:
- Electric motors and generators
- Pumps and compressors
- Industrial gearboxes
- Machine tools and automation equipment
- Conveyors and material handling systems
Choosing 6011 C3 ZKL guarantees a balance of durability, precision, and resistance to harsh operational conditions, making it an excellent choice for engineers and maintenance professionals seeking dependable bearing solutions.
