512/900-M Bearing Product Overview & Core Advantages
The 512/900-M thrust ball bearing represents a large-diameter, high-capacity solution for demanding industrial applications. Engineered specifically to accommodate pure axial (thrust) loads, this metric system bearing features an open design for customizable lubrication strategies. Its exceptional axial static load rating of over 3.5 million lbf makes it ideal for supporting immense forces in heavy machinery, while its robust construction from 52100 Chrome Steel ensures long-term durability and reliability in challenging operational environments.
512/900-M Bearing Model Code Explained, Specifications & Naming Convention
The model designation "512/900-M" provides key technical information:
- 512: Indicates the standard thrust ball bearing series with a flat seating washer.
- 900: Specifies the massive bore diameter of 900 mm.
- M: Denotes that the bearing is supplied with machined brass cage, offering superior strength and guidance for the rolling elements under high-load conditions.
512/900-M Bearing Structural Features & Performance Benefits
- High Load Capacity: The bearing's design and material selection are optimized to handle extremely high axial dynamic and static loads (442,424 lbf and 3,594,021 lbf respectively), providing robust support in heavy-duty applications.
- Open Design for Custom Lubrication: As an open bearing, it allows for the implementation of specialized lubrication systems tailored to specific operational requirements, including forced oil circulation for heat management.
- Precision Machined Components: The machined brass cage (M) ensures precise ball guidance and stability, contributing to smooth operation even under substantial loads.
- Wide Temperature Range: Suitable for operation from -30°C to 110°C, accommodating various industrial environments.
