Product Description

 

SELF-ALIGNING BALL BEARINGS

Self-aligning ball bearings are a critical component in various mechanical applications, known for their ability to accommodate misalignment and shaft deflection.these bearings consist of an inner ring, an outer ring, and rolling elements, which are uniquely designed to reduce friction and enhance operational efficiency.

The self-aligning feature allows the bearing to maintain functionality even when subjected to misalignment due to varying loads or installation errors, making it a preferred choice in dynamic environments.

TYPES OF SELF-ALIGNING BALL BEARINGS

Standard Self-Aligning Ball Bearings:
These are the most common types used in general applications. They come in various bore sizes and designs suitable for numerous setups.

Heavy-Duty Self-Aligning Ball Bearings:
Designed for high-load applications, these bearings are built with reinforced materials to withstand increased pressures and stresses.

High-Speed Self-Aligning Ball Bearings:
These are engineered to operate optimally at high speeds, ensuring minimal friction and longer service life.

Corrosion-Resistant Self-Aligning Ball Bearings:
Ideal for use in harsh environments, these bearings are often coated or made from materials that resist corrosion, ensuring longevity.

 

ADVANTAGES OF SELF-ALIGNING BALL BEARINGS

Aerospace:
Essential in various aircraft components where weight reduction and reliability are key factors.

Construction Equipment:
Used in cranes, excavators, and other heavy machinery subjected to dynamic loading and alignment challenges.

ADVANTAGES OF SELF-ALIGNING BALL BEARINGS

Enhanced Misalignment Accommodation:
They can self-adjust to compensate for shaft misalignment, ensuring steady operation and extending bearing life.

Reduced Friction:
These bearings help in minimizing friction and wear, resulting in lower energy consumption and heat generation.

ADVANTAGES OF SELF-ALIGNING BALL BEARINGS

Simplified Installation:
Their design often simplifies the installation process, reducing setup times and associated labor costs.
Versatility: Suitable for a wide range of applications, making them a versatile choice for many industries.

Long Service Life:
The materials and design features contribute to improved durability, resulting in fewer replacements and maintenance efforts.

Installation Instructions

Key Points for Installation and Maintenance

Installation Specifications

 

• Ensure that the coaxiality error between the inner hole of the bearing housing and the shaft is within the allowable range of the aligning angle.
• Use special tools for installation and avoid direct hammering on the outer ring.

Lubrication Strategies

 

• High - speed scenarios: Use low - viscosity synthetic lubricating oil (ISO VG 32).
• High - temperature/heavy - load: Use high - temperature lithium - based grease (such as Mobilith SHC 100).

Regular Inspections

 

• Monitor vibration and temperature rise, and promptly replenish grease or replace seals.
