61932 MA/C3 Bearing Product Overview & Core Advantages
The 61932 MA/C3 is a single row deep groove ball bearing engineered for exceptional radial load capacity and reliable performance in demanding applications. This metric bearing features an open design and is manufactured to ABEC 1 | ISO P0 tolerance standards, ensuring consistent quality and interchangeability. Its primary advantages include a high dynamic load rating of 20,750 lbf and a robust construction that provides stable operation. The specified C3 radial internal clearance makes it particularly suitable for applications involving thermal expansion or where interference fits are used, offering enhanced operational reliability.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 61932 | Basic bearing series: Deep Groove Ball Bearing with specific dimensions (160mm bore, 220mm OD, 28mm width) |
| MA | Machined brass cage, providing excellent strength and guidance at higher speeds |
| C3 | Radial internal clearance greater than normal, suitable for applications with thermal expansion or interference fits |
61932 MA/C3 Bearing Structural Features & Performance Benefits
Optimized Deep Groove Design: The raceway geometry enables the bearing to handle significant radial loads while accommodating moderate axial loads in both directions, making it versatile for various mounting configurations.
Machined Brass Cage (MA): This cage material offers superior strength and dimensional stability compared to stamped alternatives, contributing to reliable performance at the limiting speed of 5,000 rpm and in demanding operating conditions.
C3 Internal Clearance: The greater-than-normal radial clearance compensates for thermal expansion in applications where operating temperatures vary, preventing premature failure due to excessive preload. This feature is particularly beneficial in electric motors, pumps, and gearboxes.
Precision Manufacturing: Manufactured to ABEC 1 | ISO P0 tolerance class with tight dimensional control on bore diameter, outside diameter, and width, ensuring consistent performance and ease of installation.
