W 625 R Bearing Product Overview & Core Advantages
The W 625 is a single row deep groove ball bearing designed for exceptional performance in compact, high-precision applications. As a metric bearing with an open design, it is optimized for handling primarily radial loads and is constructed entirely from stainless steel for superior corrosion resistance. Its key advantages include a compact cross-section, a high limiting speed of 63,000 rpm, and compliance with RoHS and REACH environmental standards, making it an ideal choice for applications demanding reliability, cleanliness, and long service life.
W 625 R Bearing Model Code Explained, Specifications & Naming Convention
The model designation W 625 can be broken down as follows:
- W: Manufacturer's series prefix.
- 6: Indicates a single row deep groove ball bearing with a flanged outer ring.
- 25: Specifies the bore diameter code. For this metric bearing, it corresponds to a 5 mm bore diameter.
- No Seal Suffix: The absence of a seal suffix (e.g., -2RS) confirms the open (non-contact) seal type, allowing for higher speeds and minimal friction.
- No Cage Suffix: Indicates a standard cage, which in this case is made from stainless steel.
- No Lubrication Suffix: The bearing is supplied without lubrication ("None"), providing flexibility for the user to apply a specialized lubricant suited to their specific operating conditions.
W 625 R Bearing Structural Features & Performance Benefits
- All-Stainless-Steel Construction: Both rings, balls, and cage are manufactured from stainless steel, offering excellent resistance to corrosion and making the bearing suitable for harsh environments and wash-down applications.
- Flanged Outer Ring: The integrated flange (18 mm outer diameter) simplifies bearing mounting and alignment within a housing, reducing assembly time and cost.
- High-Speed Capability: The open design and precision construction contribute to a high limiting speed of 63,000 rpm, enabling use in demanding, high-velocity applications.
- Precision Tolerances: Manufactured to P0 (Normal) tolerance class and standard CN radial internal clearance, ensuring consistent and reliable performance for a wide range of general applications.
- Compact and Lightweight: With a small bearing size of 5x16x5 mm and a weight of only 0.0049 kg, it is ideal for space-constrained and weight-sensitive designs.
W 625 R Bearing Typical Application Areas
This bearing is commonly specified in:
- Small Electric Motors and miniature gearboxes.
- Precision Instruments, medical devices, and optical equipment.
- Office Automation Equipment such as printers and scanners.
- Food and Beverage Processing Machinery where corrosion resistance is critical.
- Various low-torque, high-speed mechanisms requiring a compact radial bearing solution.
