Understanding 2.5OD x Contact Bearings

## Design and Construction:

2.5OD x contact bearings consist of an outer ring, inner ring, and ball bearings. The outer and inner rings are typically made of high-quality steel alloys, providing strength and durability. Ball bearings, usually composed of ceramic or hardened steel, are designed to roll smoothly between the rings, minimizing friction and wear.

## Dimensions and Specifications:

As the name suggests, 2.5OD x contact bearings have an outer diameter of 2.5mm. They are available in various widths and thicknesses to accommodate different design requirements. The most common width is 0.7mm, while thicknesses range from 0.6mm to 1.2mm.

## Load Capacity and Precision:

Despite their compact size, 2.5OD x contact bearings possess impressive load capacities. They are capable of handling both radial and axial loads, making them suitable for applications involving complex forces. The precision manufacturing process ensures minimal deviation from ideal geometry, resulting in smooth operation and extended bearing life.

• Robotics: Joints and drives in collaborative robots, autonomous vehicles, and exoskeletons

Maintenance and Lubrication of 2.5OD x Contact Bearings

Proper maintenance and lubrication are crucial for optimizing the performance and lifespan of 2.5OD x contact bearings.

## Lubrication:

These bearings typically utilize grease or oil as lubricants. The appropriate lubricant should be selected based on the operating conditions, such as temperature, speed, and load.

## Cleaning and Inspection:

Regular cleaning and inspection are essential to prevent contamination and premature failure. Bearings should be periodically removed and cleaned using solvents or ultrasonic cleaners.

## Troubleshooting Common Issues:

Potential issues with 2.5OD x contact bearings can include:

• Noise: Excessive noise may indicate improper lubrication, contamination, or bearing damage.
• Vibration: Vibration can result from imbalances, misalignment, or bearing wear.
• Seizure: Bearing seizure can occur due to excessive load, inadequate lubrication, or contamination.
