D/W R1-5 Bearing Structural Features & Performance Benefits
The bearing's performance is derived from its specific construction:
- All-Stainless-Steel Construction: The rings, balls, and cage are made of stainless steel, providing superior corrosion resistance and durability in harsh or wash-down environments.
- Open Seal Type: The absence of seals minimizes friction, enabling a high limiting speed of 95,000 rpm. This design also facilitates custom lubrication strategies if required.
- Precision Tolerances: Manufactured to P0 tolerance class with a controlled radial internal clearance (CN), ensuring smooth and consistent operation, which is critical for precision applications.
- High Dynamic Load Capacity: With a radial dynamic load rating of 70 lbf, it offers reliable performance under significant radial stresses for its size.
D/W R1-5 Bearing Typical Application Areas
The D/W R1-5 is ideally suited for compact, high-speed mechanisms across various industries, including:
- Precision Instruments and optical devices
- Small DC motors and miniature gearboxes
- Medical devices and dental handpieces
- Robotics and small automation assemblies
- Computer disk drives and cooling fans
