Deep groove ball bearing SKF W 61903-2Z, Outer diameter: 30 mm | Width: 7 mm | Inner diameter: 17 mm

Ball bearings are essential mechanical components that reduce friction and support various loads in a wide range of industrial applications. Among them, deep groove ball bearings stand out for their versatility, ability to operate at high speeds, and low maintenance requirements.

This SKF deep groove ball bearing features a stainless steel cage and two metal shields, which provide effective protection against contaminants, ensuring optimal performance in many high-speed applications, including corrosive or humid environments.

Features:
This SKF bearing is equipped with a stainless steel cage, which provides high corrosion resistance, making it ideal for humid environments or those exposed to chemicals. It also features two steel sheet end shields, offering enhanced sealing against contaminants. This bearing is designed to handle moderate radial loads as well as light axial loads in both directions. Its standard radial clearance maintains low friction, enabling smooth operation at high speeds and optimal efficiency.

Maintenance:
This deep-groove ball bearing is pre-lubricated for life with high-quality grease, eliminating the need for relubrication and reducing maintenance costs. Metal shields on both sides provide effective protection against medium-sized contaminants and prevent lubricant loss. To ensure optimal service life, it is recommended to inspect the bearing regularly, paying particular attention to noise, temperature, and overall condition.

Sealing:
The two steel sheet metal flanges feature a narrow gap between the bearing’s internal components, forming an effective mechanical barrier against debris and preventing the intrusion of contaminants. By limiting lubricant loss, these flanges contribute to the bearing’s long-term performance.
