625-2RS1/W64 Bearing Product Overview & Core Advantages
The 625-2RS1/W64 is a single row deep groove ball bearing designed for exceptional reliability in compact applications. This metric bearing excels at handling primarily radial loads and offers robust performance due to its sealed construction. Its key advantages include a high limiting speed and long-term, maintenance-free operation enabled by its integrated solid lubricant, making it an ideal choice for applications demanding high precision and durability in a minimal space envelope.
625-2RS1/W64 Bearing Model Code Explained, Specifications & Naming Convention
- 625: Basic model number, indicating a single row deep groove ball bearing with a 5 mm bore.
- -2RS1: Designates that the bearing is sealed on both sides with contact seals (RS1 type), providing effective protection against contaminants.
- /W64: Indicates the bearing is pre-lubricated with Soild Oil, a solid polymeric lubricant that ensures consistent performance and is suitable for the specified temperature range.
625-2RS1/W64 Bearing Structural Features & Performance Benefits
The bearing's performance is derived from its specific construction:
Robust Sealing & Lubrication: The 2RS1 contact seals effectively shield the internal components from dust and moisture. Combined with the integrated Soild Oil (W64) lubricant, this creates a sealed-for-life system, eliminating the need for re-lubrication and preventing lubricant wash-out.
High-Speed Capability: Manufactured to ABEC 1 | ISO P0 tolerance class with a CN radial internal clearance, this bearing is precision-engineered for smooth operation, contributing to its high limiting speed of 36,000 rpm.
Durable Material Construction: All critical components, including rings, balls, and cage, are made from high-grade Chrome Steel, ensuring high strength, wear resistance, and a long service life.
625-2RS1/W64 Bearing Typical Application Areas
This bearing's compact size, sealed design, and high-speed performance make it suitable for a wide range of applications, including:
- Small Electric Motors and Gear Motors
- Precision Instruments and Optical Devices
- Computer Cooling Fans and Spindles
- Office Automation Equipment
- Medical Devices and Dental Handpieces
