61907 Bearing Product Overview & Core Advantages
The 61907 is a single row deep groove ball bearing designed for exceptional performance in precision applications. Engineered to primarily accommodate radial loads, this bearing features a P6 tolerance class for high running accuracy and dimensional stability. Its compact design, with a 35 mm bore and 55 mm outside diameter, makes it ideal for space-constrained assemblies requiring high reliability and consistent operation. The use of high-grade chrome steel for rings and balls ensures durability and long service life.
61907 Bearing Model Code Explained, Specifications & Naming Convention
- 6: Indicates the bearing series, typically associated with deep groove ball bearings.
- 1: Denotes a specific width series within the "9" dimension series.
- 9: Represents the dimension series (combination of width and outer diameter profiles).
- 07: Specifies the bore diameter. In this case, 07 indicates a 35 mm bore (07 * 5 = 35 mm).
Key Omitted Suffixes & Their Implications: The absence of suffixes like "2Z" or "RS" confirms the open (non-sealed) design. The lack of a lubrication suffix indicates it is supplied without grease ("None"), allowing for application-specific lubrication selection.
61907 Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: Manufactured to a P6 tolerance class, this bearing provides superior dimensional accuracy and run-out control, which is critical for high-speed applications and precise positioning.
- Optimized Load Capacity: With a radial dynamic load rating of 2428 lbf and a static load rating of 1754 lbf, it offers robust performance for its compact bearing dimensions (35x55x10 mm).
- High-Speed Capability: The stainless steel cage and optimized internal geometry contribute to a high limiting speed of 16,000 rpm, making it suitable for demanding rotational equipment.
- Material Integrity: Constructed from chrome steel for rings and balls, and a stainless steel cage, the bearing ensures high strength, wear resistance, and corrosion resistance in the cage for extended longevity.
- Standard Internal Clearance: The specified CN radial internal clearance is the standard group, suitable for a wide range of common operating conditions.
