W 61908 Bearing Product Overview & Core Advantages
The W 61908 is a single row deep groove ball bearing designed for high-performance applications requiring reliable radial load capacity and precision operation. Manufactured entirely from stainless steel, it offers excellent corrosion resistance and is suitable for a wide temperature range from -30°C to 120°C. Its compact design, featuring a 40 mm bore and 12 mm width, provides a space-saving solution without compromising on dynamic load rating or operational stability. This bearing is an ideal choice for applications demanding high reliability and long service life under demanding conditions.
W 61908 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| W | Designates a stainless steel bearing series |
| 61908 | Standard deep groove ball bearing designation with specific dimensions (40mm bore, 62mm OD, 12mm width) |
| Open (Seal type) | No seals or shields, allowing for higher limiting speeds and easy re-lubrication |
| P0 (Tolerance class) | Standard tolerance grade for general applications |
| CN (Radial clearance) | Normal radial internal clearance group |
W 61908 Bearing Structural Features & Performance Benefits
The W 61908 features a single row deep groove raceway design that enables it to handle significant radial loads (2675 lbf dynamic, 2203 lbf static) while accommodating moderate axial loads in both directions. The all-stainless steel construction, including rings, balls, and cage, provides superior corrosion resistance and makes it suitable for washdown environments and applications where contamination must be avoided. The open design contributes to its high limiting speed of 14,000 rpm, while the precision P0 tolerance class ensures consistent performance and smooth operation. The standard CN radial clearance makes it suitable for most general applications across the specified temperature range.
