625-2Z/C3VT127 Bearing Product Overview & Core Advantages
The 625-2Z/C3 is a metric single row deep groove ball bearing designed for reliable performance in a wide range of industrial applications. Its core advantages stem from its shielded design (2Z), which provides effective protection against contamination while retaining lubrication, and its C3 radial internal clearance, which accommodates thermal expansion for stable operation under varying thermal conditions. This bearing is engineered to handle primarily radial loads and offers a high limiting speed, making it a versatile and durable choice for compact assemblies requiring consistent performance.
Model Code Breakdown
- 625: Basic model number, indicating a deep groove ball bearing with a 5 mm bore.
- -2Z: Signifies that the bearing is equipped with non-contact shields on both sides. This provides protection from dust and other particulates without significantly increasing friction.
- /C3: Denotes a greater than normal radial internal clearance. This is ideal for applications where thermal expansion of the shaft or housing is expected, preventing preload and ensuring smooth operation.
625-2Z/C3VT127 Bearing Structural Features & Performance Benefits
The bearing's performance is defined by its robust construction and precise engineering. The single row deep groove raceway is optimized for handling radial loads efficiently. The use of chrome steel for all critical components (rings, balls, cage) ensures high strength and durability. The shielded (2Z) construction protects the internal components, enhancing bearing life in contaminated environments. The specified C3 clearance is a key feature for applications with potential thermal gradients, preventing binding and maintaining performance. Manufactured to ABEC 1 | ISO P0 tolerance class, it provides reliable and consistent operation for general precision applications.
625-2Z/C3VT127 Bearing Typical Application Areas
Due to its compact bearing dimensions (5x16x5 mm), high-speed capability, and shielded design, the 625-2Z/C3 is commonly found in:
- Small electric motors and gearboxes
- Precision instruments and medical devices
- Computer cooling fans and small spindles
- Office automation equipment and low-power drives
