6805 Bearing Product Overview & Core Advantages
The 6805 metric ball bearing is a single row deep groove ball bearing engineered for high-performance radial load applications. Designed with precision ABEC-1 tolerance and C0 radial clearance, this bearing delivers reliable operation and excellent rotational accuracy. Its compact design, featuring a 25 mm bore and 7 mm width, makes it ideal for space-constrained assemblies requiring high-speed capability up to 21,000 rpm. Manufactured from chrome steel rings and balls with a stainless steel cage, it offers superior durability and consistent performance across a temperature range of -30°C to 110°C.
6805 Bearing Model Code Explained, Specifications & Naming Convention
| Model Component | Technical Significance |
|---|---|
| 68 | Series designation indicating a light-duty, deep groove ball bearing with a 7mm width |
| 05 | Bore diameter code representing 25mm (05 × 5 = 25mm) |
| Open | No seals or shields, allowing for higher speed operation and custom lubrication options |
6805 Bearing Structural Features & Performance Benefits
Deep Groove Geometry: The optimized raceway design enables smooth operation and efficient radial load distribution, handling dynamic loads up to 968 lbf and static loads up to 662 lbf.
Precision Construction: Manufactured to ABEC-1 tolerance standards with controlled radial internal clearance (0.006-0.020mm), ensuring consistent performance and reduced vibration in precision applications.
High-Speed Capability: The stainless steel cage provides excellent stability at limiting speeds of 21,000 rpm, while the open design facilitates optimal lubrication management for high-speed operation.
Material Excellence: Chrome steel rings and balls offer superior hardness and wear resistance, complemented by a corrosion-resistant stainless steel cage for extended service life.
