D/W R156 R Bearing Product Overview & Core Advantages

The D/W R156 R is a precision-engineered single row ball bearing designed for demanding applications requiring high reliability and dimensional stability. Manufactured entirely from stainless steel, this bearing offers excellent corrosion resistance. Its open design allows for versatile lubrication options and is optimized to handle primarily radial loads. With a compact flanged outer ring, it provides secure axial location and simplified mounting in housings, making it an ideal choice for applications where space is limited and precision is paramount.

D/W R156 R Bearing Model Code Explained, Specifications & Naming Convention

Code Segment Technical Meaning
D/W Manufacturer's prefix (Dodge/Wave)
R156 The specific bearing series and size designation.
R Indicates a flanged outer ring, which aids in positioning and mounting.

Note: The absence of a seal suffix (e.g., 2Z, RS) confirms the open (unsealed) construction, and the lack of a lubrication suffix indicates it is supplied without grease.

D/W R156 R Bearing Structural Features & Performance Benefits

  • All-Stainless-Steel Construction: The rings, balls, and cage are made from stainless steel, providing superior corrosion resistance and suitability for harsh environments and washdown applications.
  • Flanged Outer Ring: The integral flange simplifies installation, prevents bearing creep, and ensures precise axial location within the housing, enhancing overall assembly rigidity.
  • Open Seal Type: The unsealed design allows for high-speed operation and permits the use of various lubrication systems to optimize performance for specific speed and temperature conditions.
  • Precision Tolerances: Manufactured to ABEC 1 (P0) tolerance class and standard CN radial internal clearance, ensuring consistent performance and smooth operation.
  • High-Speed Capability: With a limiting speed of 90,000 rpm, this bearing is engineered for high-speed applications.

D/W R156 R Bearing Typical Application Areas

The D/W R156 R is ideally suited for a wide range of precision instruments and compact machinery, including:

  • Small Precision Motors and Servo Drives
  • Medical and Dental Handpieces
  • Optical Encoders and Scanning Devices
  • Instrumentation Pulleys and Guide Rollers
  • Food Processing and Packaging Equipment (where corrosion resistance is critical)
