Bearing NJ 316 URB
The NJ 316 URB is a high-quality cylindrical roller bearing designed for robust performance in heavy-duty applications. Known for its durability and precision, this bearing is widely used in various industrial machinery to support radial loads and ensure smooth rotational movement.
This particular model, NJ 316 URB, belongs to the NJ series of cylindrical roller bearings, which feature a design that allows for axial displacement of the shaft relative to the housing in one direction. This characteristic makes it ideal for applications where thermal expansion or shaft misalignment may occur.
Key Features and Benefits
- Durability: Manufactured with high-grade steel and advanced heat treatment techniques, ensuring long service life under demanding conditions.
- Load Capacity: Capable of accommodating heavy radial loads with minimal friction.
- Design: The NJ type design includes an integral flange on the inner ring and a loose rib on the outer ring, facilitating axial displacement and allowing for easy mounting and dismounting.
- Sealing: The suffix "URB" typically indicates specific design or manufacturer features, often related to sealing or cage types, enhancing the bearing's protection against contaminants.
- Versatility: Suitable for use in electric motors, gearboxes, conveyor systems, and other industrial equipment.
Product Dimensions
The standard dimensions of the NJ 316 bearing series, which the NJ 316 URB corresponds to, are:
- Inner Diameter (d): 80 mm
- Outer Diameter (D): 140 mm
- Width (B): 33 mm
