W 629-2Z Bearing Product Overview & Core Advantages
The W 629-2Z is a single row deep groove ball bearing designed for high performance in compact spaces. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its shielded design (2Z), which effectively retains pre-applied grease and protects against contaminant ingress, ensuring reliable, low-maintenance operation. This bearing is engineered to handle primarily radial loads and is capable of high-speed operation up to 32,000 rpm, making it an ideal choice for applications demanding precision and longevity.
Model Code In-Depth Explanation
- W 629: Basic bearing designation, indicating a single row deep groove ball bearing with a 9 mm bore.
- -2Z: Signifies that the bearing is equipped with non-contact shields on both sides. This provides effective protection against contamination while minimizing friction, contributing to the high limiting speed.
W 629-2Z Bearing Structural Features & Performance Benefits
The single row deep groove raceway geometry is optimized for radial load capacity. The use of stainless steel for all components (rings, balls, cage) ensures consistent performance and resistance to corrosion in demanding environments. The shielded (2Z) construction is a critical feature, sealing in the factory-applied grease lubrication and sealing out debris. This combination delivers a robust, maintenance-free solution with a wide operating temperature range of -30°C to 120°C and a high dynamic load rating of 892 lbf.
W 629-2Z Bearing Typical Application Areas
This bearing is widely used in applications requiring compact size, corrosion resistance, and high-speed capability. Typical industries and equipment include:
- Precision Electric Motors
- Medical and Dental Equipment
- Food Processing Machinery
- Small Appliances and Power Tools
- Instrumentation and Control Devices
