D/W R168 R Bearing Product Overview & Core Advantages
The D/W R168 R is a single row deep groove ball bearing designed for precision radial load applications. Manufactured entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance and is suitable for a wide operating temperature range. This open-type bearing features a P0 tolerance class and standard CN radial internal clearance, making it an ideal choice for applications requiring reliable performance and dimensional stability in compact spaces.
D/W R168 R Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| D/W | Manufacturer Branding / Series Identifier |
| R168 | Standard Bearing Size Designation |
| R | Flange Design (as per specification: Flange outer diameter 0.42201") |
Note: The absence of suffix codes indicates an open (unsealed) design with no pre-applied lubrication.
D/W R168 R Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With a bore diameter of 0.25" and a total weight of just 0.0006 kg, this bearing is engineered for space-constrained and weight-sensitive assemblies.
- High Corrosion Resistance: The all-stainless steel construction ensures long-term reliability in harsh or washdown environments, with a temperature range of -30° to 120 °C.
- Precision Performance: The P0 tolerance class and tight dimensional tolerances on the bore diameter and outside diameter contribute to precise shaft running and reduced vibration.
- Integrated Flange: The flange design (R) with an outer diameter of 0.42201" simplifies mounting and positioning, providing secure location within a housing.
- Radial Load Capacity: Optimized for radial dynamic loads up to 48 lbf and static loads of 20 lbf, suitable for various light to moderate duty applications.
D/W R168 R Bearing Typical Application Areas
- Precision Instruments and Optical Devices
- Small Electric Motors and Encoders
- Medical and Dental Equipment
- Food Processing Machinery (where corrosion resistance is critical)
- Office Automation Equipment
- Robotic Arms and Small Actuators
