SMR62 2rs Bearing Product Overview & Core Advantages
The SMR62 2RS is a miniature sealed ball bearing engineered for precision applications requiring compact design and reliable performance. As a single row deep groove ball bearing, it is primarily designed to accommodate radial loads efficiently. Its key advantages include a fully sealed construction with nitrile rubber contact seals (2RS) that effectively retain lubrication and exclude contaminants, ensuring long service life with minimal maintenance. Manufactured entirely from stainless steel, it offers excellent corrosion resistance, making it suitable for demanding environments. With its small bearing dimensions (2mm bore, 6mm OD, 2.5mm width) and low weight, it is an ideal solution for space-constrained, high-speed mechanisms.
SMR62 2rs Bearing Model Code Explained, Specifications & Naming Convention
- SMR62: Indicates the bearing series and size (2mm bore, 6mm OD).
- 2RS: Denotes the sealing type. "2" indicates two seals, one on each side. "RS" specifies that these are Nitrile Rubber (NBR) Contact Seals, which provide superior protection against contamination and grease leakage compared to non-contact shields.
SMR62 2rs Bearing Structural Features & Performance Benefits
Robust Construction: The bearing features rings, balls, and a cage made from stainless steel, providing high corrosion resistance and durability. The deep groove raceway is optimized for handling radial loads.
Effective Sealing & Lubrication: The double-sided nitrile rubber contact seals (2RS) effectively shield the internal components from dust, moisture, and other contaminants while retaining the factory-applied lubricant. This design contributes to a maintenance-free operation under standard conditions.
High-Speed Capability: With a limiting speed of 67,500 rpm, this bearing is suitable for high-speed applications. The combination of a stainless steel cage, precision balls, and effective sealing allows for smooth operation at elevated rotational speeds.
Precision & Load Ratings: Built to ABEC1 tolerance class with a MC3 radial internal clearance (0.002mm to 0.013mm), it ensures consistent and reliable performance. It offers a dynamic load rating of 57 lbf and a static load rating of 16 lbf.
SMR62 2rs Bearing Typical Application Areas
The SMR62 2RS is widely used in applications demanding small size, high speed, and reliability, including:
- Small Precision Motors (e.g., drone motors, small DC motors)
- Medical and Dental Handpieces
- Office Automation Equipment (e.g., printers, scanners)
- Instrumentation and Control Devices
- Radio Control Models and miniature gearboxes
