61804-2RS1/C3LHT23 Bearing Product Overview & Core Advantages
The 61804-2RS1/C3LHT23 is a miniature deep groove ball bearing designed for compact, high-precision applications. As a single row bearing with integral seals (2RS1), it offers reliable protection against contamination. Its key advantages include a compact cross-section, the ability to handle primarily radial loads, and long service life due to its sealed and pre-lubricated design. Manufactured to ABEC 1 | ISO P0 tolerance standards, it ensures consistent performance and high reliability in demanding, space-constrained environments.
Model Code Breakdown
- 61804: Basic series designation for a miniature deep groove ball bearing with a 20mm bore and 32mm outside diameter.
- 2RS1: Signifies contact seals on both sides of the bearing, providing effective protection against dust and moisture ingress.
- C3: Indicates a greater than normal radial internal clearance, suitable for applications with higher operating temperatures or where interference fits are used.
- LHT23: Denotes that the bearing is pre-lubricated with a specific high-temperature grease, allowing for immediate use and extended maintenance-free operation.
61804-2RS1/C3LHT23 Bearing Structural Features & Performance Benefits
The bearing's performance is derived from its robust construction. The single row deep groove raceway and high-quality chrome steel components provide excellent durability and load-carrying capacity for its compact size. The contact seals (2RS1) effectively retain lubricant and exclude contaminants, significantly enhancing operational reliability. The specified C3 radial internal clearance accommodates thermal expansion, making it suitable for applications with varying operational temperatures. The pre-lubrication with LHT23 grease ensures immediate startup and consistent performance across its specified temperature range of -30°C to 120°C.
61804-2RS1/C3LHT23 Bearing Typical Application Areas
This bearing is ideally suited for applications requiring a compact, sealed, and reliable solution. Common uses include:
- Small electric motors and gear motors
- Precision instruments and medical devices
- Office automation equipment (printers, scanners)
- Computer cooling fans and spindle drives
- Various light-duty industrial machinery
