SET2520 2RS Bearing Product Overview & Core Advantages
The SET2520 2RS is a metric single row deep groove ball bearing designed for high reliability in compact applications. Its core advantages stem from its sealed construction and stainless steel components, providing excellent corrosion resistance. This bearing is engineered to primarily handle radial loads efficiently while offering a compact cross-section, making it ideal for applications where space is limited and environmental protection is required.
SET2520 2RS Bearing Model Code Explained, Specifications & Naming Convention
- SET: Indicates a standard bearing series with a specific internal design.
- 25: Specifies the outside diameter of 25 mm.
- 20: Denotes the bore diameter of 20 mm.
- 2RS: Signifies that the bearing is fitted with contact rubber seals on both sides. This provides superior protection against contaminants and retains lubricant effectively.
SET2520 2RS Bearing Structural Features & Performance Benefits
The bearing's performance is defined by its robust construction. The single row deep groove raceway is optimized for smooth operation under radial dynamic loads (rated at 204 lbf). The use of stainless steel for all critical components (rings, balls, cage) ensures superior corrosion resistance and operational integrity in harsh environments. The 2RS seals are a critical feature, enabling a maintenance-free service life by protecting the internal lubrication and preventing ingress of moisture and debris. Manufactured to ABEC-1 tolerance class, it guarantees consistent and reliable performance for a wide range of industrial applications.
