SMR148 2rs Bearing Product Overview & Core Advantages
The SMR148 2RS is a single row deep groove ball bearing designed for high reliability in compact applications. Engineered with stainless steel rings and balls, it offers excellent corrosion resistance. A key feature is its integral 2RS double lip contact seals, which provide superior protection against contaminants while retaining lubricant, making it suitable for applications demanding long-term, maintenance-free operation. Its compact design, with a 4 mm width, is ideal for space-constrained assemblies requiring robust radial load capacity.
SMR148 2rs Bearing Model Code Explained, Specifications & Naming Convention
- SMR148: Basic model number denoting a metric, single row deep groove ball bearing with an 8 mm bore, 14 mm outside diameter, and 4 mm width.
- 2RS: Signifies the bearing is equipped with two rubber contact seals (one on each side). These seals provide effective protection against dust, moisture, and other contaminants.
SMR148 2rs Bearing Structural Features & Performance Benefits
Robust Construction: Manufactured entirely from stainless steel (rings, balls, and cage), this bearing ensures high corrosion resistance and durability in harsh environments.
Effective Sealing: The double lip contact seals (2RS) significantly extend bearing service life by preventing lubricant loss and excluding contaminants, enabling reliable operation.
Precision & Load Capacity: Built to ABEC1 tolerance standards, it ensures consistent performance. With a radial dynamic load rating of 141 lbf, it handles significant radial loads for its compact size.
Versatile Operating Range: The bearing operates effectively within a temperature range of -30°C to 110°C, making it suitable for a wide array of industrial applications.
SMR148 2rs Bearing Typical Application Areas
The SMR148 2RS is ideally suited for applications requiring a compact, sealed, and corrosion-resistant bearing solution. Common uses include:
- Small Electric Motors and Gearboxes
- Medical and Dental Equipment
- Food Processing Machinery
- Precision Instruments and Optical Devices
- Office Automation Equipment (e.g., printers, scanners)
