Product detailed description
Bearing NJ 215 DKF
The NJ 215 DKF is a high-quality cylindrical roller bearing designed for heavy-duty applications requiring reliable performance and durability. Manufactured to meet international standards, this bearing ensures smooth rotational movement while handling substantial radial loads.
This specific model, NJ 215 DKF, is part of the NJ series of cylindrical roller bearings known for their robust design featuring a solid inner ring with two integral flanges and a separable outer ring with a single flange. This configuration allows the bearing to accommodate axial displacement in one direction, making it ideal for applications where shaft expansion or contraction occurs.
Key Features and Benefits
- Durability: Engineered with high-grade materials to withstand heavy radial loads and harsh operating conditions.
- Precision: Manufactured with tight tolerances for smooth, low-friction rotation.
- Versatility: Suitable for a wide range of industrial machinery including electric motors, gearboxes, and pumps.
- Ease of Assembly: Separable design facilitates installation, inspection, and maintenance.
- Axial Load Accommodation: Can support axial displacement in one direction, accommodating thermal expansion of the shaft.
Dimensions and Specifications
The NJ 215 DKF bearing conforms to standard dimensions as per ISO and DIN bearing standards. The typical dimensions for the NJ 215 DKF bearing are:
- Inner Diameter (d): 75 mm
- Outer Diameter (D): 130 mm
- Width (B): 31 mm
These dimensions make the NJ 215 DKF suitable for medium to large industrial equipment where space constraints and load requirements must be carefully balanced.
Applications
The NJ 215 DKF bearing is widely used across various industries including manufacturing, automotive, and heavy machinery. Its capacity to handle high radial loads and limited axial displacement makes it perfect for:
- Electric motors and generators
- Gearboxes and speed reducers
- Pumps and compressors
- Machine tool spindles
- Conveyor systems and material handling equipment
Choosing the NJ 215 DKF ensures enhanced performance, longer service life, and reduced downtime in critical mechanical systems.
