61800 Bearing Product Overview & Core Advantages
The 61800 is a metric single row deep groove ball bearing engineered for high-precision applications requiring reliable performance under radial loads. Characterized by its compact design with a 10 mm bore and a 5 mm width, this bearing offers an exceptional balance of size and capacity. Manufactured to a P6 tolerance class, it ensures superior running accuracy and rotational stability. Its open design allows for versatile lubrication options, making it suitable for high-speed operations up to 48,000 rpm. This bearing is an ideal choice for applications demanding high precision, compact dimensions, and consistent operation.
61800 Bearing Model Code Explained, Specifications & Naming Convention
The model number 61800 follows a standard industry designation. Below is a breakdown of its key characteristics implied by the series and specifications:
- 61: Denotes the extra-thin section, deep groove series.
- 800: Indicates the specific size with a 10mm bore (bore = 800 / 5 = 10mm).
- Open (No Seal/Shield suffix): The bearing is supplied without seals or shields, allowing for high-speed operation and custom lubrication.
- P6 Tolerance: Signifies a higher precision grade than standard, offering tighter dimensional and running accuracy.
- CN Radial Clearance: Represents the standard, normal range of internal clearance.
61800 Bearing Structural Features & Performance Benefits
- High Precision and Stability: Built to a P6 tolerance class, this bearing guarantees minimal dimensional variation and excellent rotational precision, which is critical for sensitive machinery.
- Optimized for High Speeds: The open construction and stainless steel cage minimize friction and allow for a high limiting speed of 48,000 rpm, making it suitable for demanding rotational applications.
- Robust Load Capacity: Despite its compact size, it features a dynamic load rating of 387 lbf and a static load rating of 187 lbf, providing reliable performance under significant radial stresses.
- Durable Material Construction: The use of chrome steel for rings and balls ensures high hardness and wear resistance, while the stainless steel cage offers excellent corrosion resistance and durability.
61800 Bearing Typical Application Areas
This single row deep groove ball bearing is widely used in precision instruments and compact machinery, including:
- Precision Electric Motors and small spindles
- Office Automation Equipment (e.g., printers, scanners)
- Medical Devices and dental handpieces
- Instrumentation and control systems
- Small gearboxes and high-speed drives
