SMF83 Bearing Product Overview & Core Advantages
The SMF83 is a metric single row deep groove ball bearing engineered for compact, high-precision applications requiring reliable performance. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its primary function is to support radial loads efficiently. The bearing features a standard open design, allowing for versatile re-lubrication options to suit specific operational needs. With its small bore diameter of 3 mm and lightweight construction, it is ideal for applications where space and weight are critical constraints.
SMF83 Bearing Model Code Explained, Specifications & Naming Convention
The model code SMF83 designates a specific bearing series. While the full suffix breakdown is proprietary, the provided specifications detail its core configuration:
- Seal Type: Open (No seal or shield)
- Lubrication: Required (Not pre-greased from factory)
- Cage Material: Stainless Steel
- Tolerance Class: ABEC1
- Internal Clearance: MC3
SMF83 Bearing Structural Features & Performance Benefits
The SMF83's performance is derived from its precision engineering and material selection:
- High Corrosion Resistance: Manufactured from stainless steel for the rings, balls, and cage, making it suitable for harsh environments and washdown applications.
- Precision & Smooth Operation: Built to ABEC1 tolerance standards, ensuring consistent quality and low noise and vibration levels.
- Optimized Load Capacity: The deep groove raceway and 7-ball complement provide a robust radial dynamic load rating of 68 lbf for its compact size.
- Versatile Application Fit: The open design and "lubrication required" status offer flexibility, allowing engineers to select the optimal grease or oil for specific speed and temperature conditions, potentially achieving the specified limiting speed of 54,000 rpm.
- Integrated Flange: The outer ring flange (9.2 mm diameter) simplifies mounting and positioning within a housing, enhancing assembly accuracy and stability.
SMF83 Bearing Typical Application Areas
The SMF83 is ideally suited for a wide range of small, precision machinery and devices, including:
- Small DC Motors and Miniature Gearboxes
- Medical and Dental Hand Tools
- Precision Instruments and Optical Encoders
- Office Automation Equipment (e.g., Printers, Scanners)
- Radio-Control Models and Drones
- Small Pumps and Fans
