605 Bearing Product Overview & Core Advantages
The 605 metric ball bearing is a precision-engineered single row deep groove ball bearing designed for high-performance applications requiring reliable radial load capacity. Constructed from high-grade chrome steel with a stainless steel cage, this bearing offers excellent durability and smooth operation. Its compact design, with a 5 mm bore diameter and 14 mm outside diameter, makes it ideal for space-constrained assemblies. The bearing operates efficiently within a temperature range of -30° to 110 °C and complies with ROHS and REACH standards, ensuring both performance and environmental safety.
605 Bearing Model Code Explained, Specifications & Naming Convention
| Code Element | Technical Meaning |
|---|---|
| 605 | Standard metric series designation for a single row deep groove ball bearing with a 5mm bore. |
| Open (Seal Type) | The bearing is unsealed, allowing for custom lubrication solutions but requiring a clean operating environment. |
| ABEC1 | Specifies the tolerance class, indicating standard precision levels suitable for a wide range of general applications. |
| MC3 | Denotes the radial internal clearance group (C3), which is greater than normal, making it suitable for applications with thermal expansion or where interference fits are used. |
605 Bearing Structural Features & Performance Benefits
- Optimized Load Capacity: The single row deep groove construction is primarily designed to support significant radial loads (dynamic: 254 lbf, static: 91 lbf), while also accommodating moderate axial loads in both directions.
- High-Speed Capability: Featuring a lightweight stainless steel cage and precision-ground chrome steel components, the bearing achieves a limiting speed of 40,000 rpm, making it a capable high-speed bearing for demanding applications.
- Precision and Stability: Manufactured to ABEC1 tolerance standards, it ensures consistent running accuracy and low vibration, contributing to the overall performance of the system.
- Versatile Internal Clearance: The MC3 (C3) radial internal clearance provides operational flexibility in applications prone to thermal expansion or where tight fits are required.
605 Bearing Typical Application Areas
This 605 ball bearing is widely used in various compact and high-speed mechanisms, including:
- Small electric motors and precision instruments
- Office machinery and computer cooling fans
- Medical devices and dental handpieces
- Radio-control models and drones
- Textile machinery spindles
