E2.625-2Z/C3 Bearing Product Overview & Core Advantages
The E2.625-2Z/C3 is a metric single row deep groove ball bearing engineered for reliable performance in demanding applications. Its compact design combines a 5 mm bore with a 16 mm outside diameter, making it ideal for space-constrained assemblies. A key feature is its shielded (2Z) construction, which offers effective protection against contaminant ingress while retaining lubrication. Pre-lubricated for immediate use, this bearing is characterized by its enhanced internal clearance (C3), which accommodates thermal expansion and ensures stable operation under varying thermal conditions. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers consistent performance for general industrial use.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| E2.625 | Bearing series and size designation (5 mm bore, 16 mm OD) |
| 2Z | Bearing is equipped with shields on both sides for contaminant protection |
| /C3 | Specifies a greater radial internal clearance than normal, suitable for applications with thermal expansion or where interference fits are used |
E2.625-2Z/C3 Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured from chrome steel for rings, balls, and cage, this bearing provides excellent durability. With a dynamic load rating of 256 lbf and a static load rating of 85 lbf, it is well-suited for applications involving significant radial loads.
- Shielded for Protection & Long Life: The non-contact 2Z shields effectively seal the bearing from dust and debris without significantly increasing friction, contributing to a long service life and making it a maintenance-free solution in many environments.
- Optimized for Thermal Stability: The C3 radial internal clearance is a critical feature that allows the bearing to perform reliably in applications where operational temperatures may cause expansion of the inner ring, shaft, or housing, preventing binding and premature failure.
- Balanced High-Speed Performance: Featuring a limiting speed of 48,000 rpm, the bearing's precision-ground components and stable cage design enable smooth operation at high rotational speeds.
E2.625-2Z/C3 Bearing Typical Application Areas
