62302-2RS1/C3MT33 Bearing Product Overview & Core Advantages
The 62302-2RS1/C3MT33 is a single row deep groove ball bearing designed for high reliability in demanding applications. This sealed bearing excels at handling significant radial loads and moderate axial loads in both directions. Its compact design, featuring a 15 mm bore and 42 mm outside diameter, makes it an ideal choice for applications where space is limited but performance cannot be compromised. The combination of precision manufacturing to ABEC 1 standards and a C3 radial internal clearance ensures stable operation and accommodates thermal expansion in a wide operating temperature range.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 62302 | Basic model number for a single row deep groove ball bearing with specific dimensions (15x42x17 mm). |
| 2RS1 | Features contact rubber seals on both sides, providing superior protection against contaminants and moisture retention of lubricant. |
| C3 | Indicates a greater than normal radial internal clearance, suitable for applications with significant thermal gradients or where interference fits are used. |
| MT33 | Pre-lubricated with a high-quality polyurea grease, offering a wide operating temperature range (-30°C to +120°C) and extended service life. |
62302-2RS1/C3MT33 Bearing Structural Features & Performance Benefits
Robust Construction for High Load Capacity: Manufactured entirely from chrome steel, including rings, balls, and cage, this bearing ensures high strength and durability. Its deep groove raceway geometry is optimized to support high radial dynamic load ratings of 2563 lbf, making it exceptionally reliable under continuous operation.
Enhanced Sealing for Long Service Life: The 2RS1 double-contact seals effectively shield the internal components from dust, dirt, and other contaminants. This sealing solution, combined with the pre-applied MT33 grease, creates a maintenance-free system ideal for applications where re-lubrication is difficult or impossible.
Optimized for Stable Performance: The C3 clearance provides operational stability in environments prone to thermal expansion, preventing premature failure due to excessive preload. With a limiting speed of 12,000 rpm, it is well-suited for a variety of high-speed applications.
62302-2RS1/C3MT33 Bearing Typical Application Areas
