W 61807-2RS1 Bearing Product Overview & Core Advantages
The W 61807-2RS1 is a metric single row deep groove ball bearing designed for high-performance applications requiring reliability and precision. Its core advantages stem from its sealed construction and use of stainless steel throughout its components, making it highly resistant to corrosion. This bearing is engineered to primarily handle radial loads efficiently while offering a compact cross-section with a width of just 7 mm. It is pre-lubricated with grease, providing long-term, maintenance-free operation within a wide temperature range of -30° to 120 °C, and complies with major industry regulations like ROHS and REACH.
W 61807-2RS1 Bearing Model Code Explained, Specifications & Naming Convention
- W: Denotes a bearing with a stainless steel design for enhanced corrosion resistance.
- 61: Indicates the bearing series, signifying a deep groove design with a very low cross-section.
- 807: Specifies the bore size code. For metric bearings, this corresponds to a bore diameter of 35 mm.
- 2RS1: This suffix indicates that the bearing is equipped with two contact seals (RS1 type) on both sides. These seals effectively protect against contamination and retain lubricant, contributing to the bearing's maintenance-free characteristics.
W 61807-2RS1 Bearing Structural Features & Performance Benefits
Robust Construction: Manufactured entirely from stainless steel (rings, balls, and cage), this bearing offers superior corrosion resistance, making it ideal for harsh environments and applications requiring washdown.
Radial Load Capacity: As a single row deep groove ball bearing, it is optimized to carry significant radial dynamic loads (834 lbf) and radial static loads (753 lbf).
Sealed & Pre-Lubricated Design: The integral 2RS1 contact seals provide excellent protection against contaminants and moisture. Combined with factory-applied grease lubrication, this ensures long service life and reliable, maintenance-free operation.
High-Speed Capability: The bearing features a limiting speed of 8,500 rpm, enabled by its precision construction, stable stainless steel cage, and effective sealing and lubrication system.
Precision & Reliability: Built to P0 tolerance class and standard CN radial internal clearance, it delivers consistent performance for a wide range of general precision applications.
W 61807-2RS1 Bearing Typical Application Areas
The W 61807-2RS1 is versatile and finds use in various demanding sectors, including:
- Food and Beverage Processing Equipment: Where corrosion resistance and clean operation are critical.
- Medical and Laboratory Devices: Requiring precise, reliable, and contamination-free rotation.
- Electric Motors and Small Gearboxes: Benefiting from its compact size and high-speed capability.
- Agricultural Machinery: For components exposed to weather and corrosive agents.
- Material Handling Systems: Such as conveyor rollers, where sealed, maintenance-free bearings are essential.
