W 61906-2Z Bearing Product Overview & Core Advantages
The W 61906-2Z is a single row deep groove ball bearing designed for high performance in compact spaces. Engineered with stainless steel components, it offers excellent corrosion resistance and is pre-lubricated with grease for long-term operation. Its primary advantage lies in its ability to handle radial loads efficiently while also accommodating moderate axial loads in both directions. The inclusion of shielded seals ensures contamination protection, making it a highly reliable and low-maintenance solution for applications demanding precision and durability.

W 61906-2Z Bearing Structural Features & Performance Benefits
- Corrosion Resistance: Constructed entirely from stainless steel (rings, balls, cage), this bearing is ideal for applications exposed to moisture, chemicals, or washdown environments, ensuring long service life.
- Compact & Lightweight Design: With a 9 mm width and a weight of only 0.048 kg, it is engineered for space-constrained applications without compromising on performance.
- Sealed & Pre-Lubricated: The 2Z shields protect the internal components from dust and debris, while the factory-applied grease lubrication provides long-term, maintenance-free operation within its specified temperature range.
- Precision & Load Capacity: Manufactured to P0 tolerance class with CN radial internal clearance, it ensures consistent performance. It offers a dynamic load rating of 1403 lbf and a static load rating of 1124 lbf, providing reliable support for various radial loads.
W 61906-2Z Bearing Typical Application Areas
This versatile bearing is commonly specified in:
- Food & Beverage Processing Equipment (due to stainless steel construction and corrosion resistance)
- Medical and Laboratory Devices (requiring precision and clean operation)
- Electric Motors and Small Gearboxes (benefiting from its compact size and speed capability)
- Conveyor Systems and other material handling equipment
- Various industrial machinery where reliability and low maintenance are critical.
