S7018 CE/P4BVG275 Bearing Product Overview & Core Advantages
The S7018 CE/P4BVG275 is a precision angular contact ball bearing designed for high-performance applications requiring exceptional rotational accuracy and rigidity. Engineered to the P4 (ABEC-7) tolerance class, it delivers superior running precision. Its key advantage lies in its ability to accommodate combined loads—simultaneously handling significant radial loads and axial loads in one direction—making it an ideal choice for high-speed spindles and other demanding machinery where high rigidity and operational reliability are paramount.
S7018 CE/P4BVG275 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7018 | Basic bearing series designation, indicating a 90mm bore, 140mm OD, and 24mm width. |
| CE | Indicates a 15° contact angle and specific internal design optimized for high-speed operation and stiffness. |
| P4 | Specifies the tolerance class equivalent to ABEC-7, ensuring ultra-precise dimensions and runout for high-accuracy applications. |
| B | Denotes a preload is applied, increasing rigidity and minimizing axial/radial play under operational conditions. |
| VG275 | Specifies the type of high-performance grease used for lubrication, suitable for the specified temperature range and speed. |
S7018 CE/P4BVG275 Bearing Structural Features & Performance Benefits
