695 Bearing Product Overview & Core Advantages
The 695 metric ball bearing is a fundamental single row deep groove ball bearing designed for reliable performance in a wide array of applications. Engineered to primarily support radial loads, this open-type bearing offers a compact and versatile solution. Manufactured to ABEC1 precision class tolerances, it provides a cost-effective balance of performance and accuracy. Its compact bearing dimensions (5mm bore, 13mm OD, 4mm width) make it ideal for applications with strict space constraints, while its robust construction ensures dependable operation.
695 Bearing Model Code Explained, Specifications & Naming Convention
The model number 695 follows a standard metric designation for deep groove ball bearings. The "6" indicates a single row deep groove type, while "95" specifies the dimensional series. Key characteristics derived from the product specifications are:
- Open (No Seal/Shield Suffix): The bearing is supplied without seals or shields, allowing for custom lubrication schemes and enabling higher limiting speeds.
- Standard Cage (No Specific Suffix): Features a standard stainless steel cage for reliable ball guidance and durability.
- Internal Clearance: Designated as C3, indicating a greater than normal radial internal clearance (0.002mm to 0.013mm) suitable for applications with thermal expansion or where interference fits are used.
- Tolerance Class: Manufactured to ABEC1 precision standards, ensuring consistent quality and dimensional accuracy.
695 Bearing Structural Features & Performance Benefits
The performance of the 695 bearing is a direct result of its design and material selection:
- Robust Load Capacity: The single row deep groove construction is optimized to carry significant radial loads (Dynamic: 206 lbf, Static: 78 lbf), making it a reliable choice for various mechanical drives.
- High-Speed Capability: With a limiting speed of 43,000 rpm, this bearing is well-suited for high-speed applications. The open design and stainless steel cage contribute to this performance by reducing friction and mass.
- Precision Engineering: Built to ABEC1 tolerance class, this precision bearing ensures smooth, low-vibration operation, which is critical for the accuracy of sensitive equipment.
- Durable Material Construction: Both rings and balls are made from high-carbon chrome steel, providing excellent wear resistance and a long service life. The stainless steel cage offers enhanced corrosion resistance.
695 Bearing Typical Application Areas
The 695 deep groove ball bearing is a versatile component found in numerous precision devices and small machinery, including:
- Small Electric Motors and Gearboxes
- Precision Instruments and Optical Encoders
- Computer Cooling Fans
- Office Automation Equipment (Printers, Scanners)
- Radio-Controlled Models and Drones
