61916 Bearing Product Overview & Core Advantages
The 61916 is a single row deep groove ball bearing designed for exceptional performance in applications requiring high precision and reliability. Engineered to primarily accommodate radial loads, its compact cross-section and robust construction make it an ideal choice for space-constrained, high-speed assemblies. Manufactured to a P6 tolerance class, this bearing ensures superior running accuracy and operational consistency, making it a cornerstone component for demanding industrial machinery.
61916 Bearing Model Code Explained, Specifications & Naming Convention
The model designation 61916 follows a standardized coding system that reveals its key technical attributes:
- 6: Indicates the series, signifying a deep groove ball bearing with an extra-light cross-section.
- 19: Represents the bore diameter code. For metric bearings, this code corresponds to a bore diameter of 80 mm.
- 16: Denotes the width series, indicating a width of 16 mm.
Key Suffix Explanations:
- No Seal Suffix: The bearing is of Open construction, allowing for optimal heat dissipation and the application of specific lubrication regimes.
- P6: Specifies a tolerance class tighter than standard, providing enhanced dimensional and running accuracy.
- CN: Indicates the standard radial internal clearance for normal operating conditions.
61916 Bearing Structural Features & Performance Benefits
The design of the 61916 bearing translates directly into significant performance benefits for engineers and designers:
- High Precision & Rigidity: The single row design with a P6 tolerance class ensures minimal runout and high rotational accuracy, which is critical for the smooth operation of precision spindles and instruments.
- Optimized Load Capacity: With a dynamic load rating of 5643 lbf and a static load rating of 4586 lbf, it is capable of handling significant radial loads, providing long-term operational reliability.
- Superior High-Speed Capability: The stainless steel cage and optimized internal geometry contribute to a high limiting speed of 7,500 rpm, making it suitable for demanding high-speed applications.
- Robust Material Construction: Manufactured from chrome steel for the rings and balls, and a stainless steel cage, the bearing offers excellent durability and resistance to wear.
61916 Bearing Typical Application Areas
