1110 Bearing Product Overview & Core Advantages
The 1110 thrust ball bearing is a metric single-direction thrust bearing engineered for applications requiring high-precision axial load support. Its primary function is to accommodate heavy thrust loads in one direction while operating at moderate speeds. Manufactured from 52100 Chrome Steel for both rings and balls, this bearing offers excellent durability and wear resistance. Its compact design and precise dimensional tolerances make it an ideal component for assemblies where space is constrained and reliable axial positioning is critical.
1110 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Interpretation |
|---|---|
| 1110 | Standard model number for a metric series single-direction thrust ball bearing. |
| Open (Seal Type) | The bearing is unsealed, allowing for optimal heat dissipation and the application of specific lubricants suited for the operating environment. Lubrication is required for operation. |
1110 Bearing Structural Features & Performance Benefits
- High Axial Load Capacity: Designed specifically to handle significant thrust loads, with a high axial static load rating of 16,970 lbf and a dynamic rating of 2,450 lbf, ensuring reliable performance under demanding conditions.
- Precision Ground Components: The tight dimensional tolerances on the bore, outside diameter, and width guarantee precise shaft and housing fits, contributing to accurate axial positioning and reduced system vibration.
- Robust Material Construction: The use of 52100 Chrome Steel for the rings, balls, and cage provides a consistent and hardened structure, offering excellent resistance to wear and a long operational life.
- Moderate Speed Capability: With a limiting speed of 4,180 rpm, this bearing is suitable for a wide range of industrial applications requiring moderate rotational velocities.
1110 Bearing Typical Application Areas
This thrust ball bearing is commonly specified in machinery and systems where heavy axial loads are present. Key sectors include:
- Automotive: Used in steering mechanisms and clutch release bearings.
- Industrial Machinery: Ideal for machine tool tables, screw jacks, and lifting equipment.
- Pumps and Compressors: Supports axial loads in vertical pump shafts and compressor crankshafts.
- Agricultural Equipment: Employed in gearboxes and power transmission systems.
