FAQ
What is a cylindrical roller bearing?
A cylindrical roller bearing is a type of rolling bearing characterized by cylindrical rollers as the rolling elements. It is designed to accommodate heavy radial loads and can also bear certain axial loads (depending on the specific design). These bearings are suitable for high-speed applications requiring precise operation, such as machine tool spindles, electric motors, gearboxes, etc.
What are the main types of cylindrical roller bearings?
There are several main types:
•Single-row cylindrical roller bearings: The basic form, consisting of an outer ring, inner ring, and one row of cylindrical rollers.
•Double-row cylindrical roller bearings: Incorporating two rows of cylindrical rollers arranged face-to-face, offering higher load capacity.
•Four-row cylindrical roller bearings: Designed for heavy-duty applications with even greater load-bearing capacity and stiffness.
•Full complement: Bearings without a cage between the rollers, increasing load capacity but at the expense of lower speeds.•Series like NU, NJ, NUP, NF, categorized based on the presence or absence of shoulders on the rings and differing designs.
How do you choose the appropriate size for a cylindrical roller bearing?
Selecting the right bearing size involves considering factors such as:
Load capacity: Based on the actual radial and axial loads in operation.
•Speed requirements: High-speed applications necessitate consideration of limiting speed and thermal expansion.
•Installation space: Ensuring the selected bearing fits within the design envelope of the equipment.
•Operating environment: Factors like temperature, humidity, and contamination levels may influence material selection and sealing needs.
