6203-Z/W64 Bearing Product Overview & Core Advantages
The 6203-Z/W64 is a single row deep groove ball bearing designed for exceptional reliability in demanding applications. This metric bearing features a shielded design and is pre-lubricated with Solid Oil, making it a robust, low-maintenance solution. Engineered with chrome steel components, it delivers a high radial dynamic load rating of 2147 lbf and is capable of operating at speeds up to 17,000 rpm. Its ABEC 1 (ISO P0) tolerance ensures consistent performance, making it an ideal choice for applications requiring dependable operation under radial loads.
6203-Z/W64 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Advantage |
|---|---|---|
| 6203 | Standard designation for a single row deep groove ball bearing with a 17mm bore, 40mm OD, and 12mm width. | Standardized bearing dimensions for easy interchangeability. |
| -Z | Denotes a non-contact shield on one side of the bearing. | Provides effective contamination protection with minimal impact on limiting speed. |
| /W64 | Specifies the bearing is filled with Solid Oil polymer-based lubricant. | Ensures long-term lubrication, eliminates leakage, and is suitable for a wide temperature range (-30°C to +120°C). |
6203-Z/W64 Bearing Structural Features & Performance Benefits
The single row deep groove ball bearing construction of the 6203-Z/W64 provides a versatile and efficient design. The deep groove raceways enable it to handle not only significant radial loads but also moderate axial loads in both directions. The incorporation of a shield (Z) on one side effectively protects the bearing interior from contaminants like dust and debris, significantly enhancing operational lifespan in unclean environments.
The most significant performance benefit is derived from the Solid Oil (W64) lubrication. This solid polymer matrix, saturated with oil, replaces traditional grease. It does not leak, even at high speeds or in vertical orientations, and provides a consistent lubricating film. This makes the bearing effectively maintenance-free for its entire service life, reducing total cost of ownership. The use of high-grade chrome steel for all rolling elements and rings ensures high durability and resistance to wear, contributing to the bearing's high dynamic and static load ratings.
6203-Z/W64 Bearing Typical Application Areas
