D/W R4 R Bearing Product Overview & Core Advantages
The R4 R is a single row deep groove ball bearing designed for precision and reliability in demanding applications. Manufactured entirely from stainless steel, it offers excellent corrosion resistance. Its open design and P0 tolerance class ensure smooth operation and high rotational accuracy, making it ideal for applications requiring consistent performance under radial loads. The compact inch dimensions provide a versatile solution for various precision assemblies.
D/W R4 R Bearing Model Code Explained, Specifications & Naming Convention
The model designation R4 R can be broken down as follows:
- R4: Indicates the specific bearing size and series in inch dimensions.
- R: Signifies that the bearing is manufactured with a stainless steel construction for enhanced corrosion resistance.
Key specifications derived from the model and data include:
- Seal Type: Open (No seal or shield)
- Lubrication: None (Requires external lubrication)
- Clearance: CN (Normal radial internal clearance)
D/W R4 R Bearing Structural Features & Performance Benefits
The R4 R bearing's performance is defined by its robust construction and material selection:
- Full Stainless Steel Construction: The rings, balls, and cage are made of stainless steel, providing superior resistance to rust and corrosion, which is critical for applications in harsh environments or requiring frequent washdowns.
- High Precision (P0 Class): Manufactured to ABEC 1 (P0) tolerance standards, this bearing ensures reliable and smooth operation with minimal vibration, contributing to the overall accuracy of the assembly.
- Radial Load Capacity: Engineered to handle significant radial dynamic loads (192 lbf), making it suitable for a wide range of mechanical drives and precision instruments.
- Open Design: The absence of seals or shields allows for higher limiting speeds and facilitates easy access for lubrication, enabling customization based on specific application needs.
D/W R4 R Bearing Typical Application Areas
The R4 R deep groove ball bearing is widely used in various industries and equipment, including:
- Precision Instruments and optical devices
- Medical Equipment and dental handpieces
- Food Processing Machinery due to its stainless steel and corrosion-resistant properties
- Small electric motors and gearboxes
- Office automation equipment and low-torque drives
