694zz Bearing Product Overview & Core Advantages
The 694zz is a single row deep groove ball bearing designed for high performance in compact spaces. Engineered with shielded construction, it offers reliable protection against contamination while maintaining smooth operation. This bearing is optimized for radial loads and is capable of moderate axial loads in both directions. Manufactured to ABEC1 precision class, it provides a cost-effective solution for applications requiring consistent performance and long service life. Its compact dimensions (4mm bore, 11mm OD, 4mm width) make it ideal for space-constrained designs.

| 69 | Extra Small & Thin Series | Ultra-compact design with minimal cross-section |
| 4 | Bore Diameter: 4mm | Standard metric bore size |
| zz | Double Metal Shields | Enhanced contamination protection on both sides |
694zz Bearing Structural Features & Performance Benefits
Optimized Load Capacity: The deep groove raceway design enables efficient handling of radial loads (183 lbf dynamic, 63 lbf static) while accommodating moderate axial loads in both directions.
Shielded Protection: Double metal shields (zz) provide effective sealing against dust and particulate contamination, extending bearing life without significantly increasing friction.
Precision Engineering: Manufactured to ABEC1 tolerance standards with MC3 radial clearance (0.002mm to 0.013mm), ensuring consistent performance and smooth operation.
High-Speed Capability: With a limiting speed of 48,000 rpm, the bearing is suitable for high-speed applications when properly lubricated.
Premium Materials: Constructed with chrome steel rings and balls, and stainless steel cage, providing excellent durability and corrosion resistance.
