Understanding 61903 2RS Bearings: An Overview
What Are 61903 2RS Bearings?
61903 2RS bearings are a type of deep groove ball bearing. They are small, yet mighty components used in many machines. The ‘61903’ refers to the bearing’s size and design. ‘2RS’ means it has rubber seals on both sides.
These bearings have a few key features:
- Inner diameter of 17mm
- Outer diameter of 30mm
- Width of 7mm
- Sealed design for protection
- Ability to handle both radial and axial loads
61903 2RS bearings are known for their versatility. They can work in various speeds and loads. This makes them popular in many industries. From cars to farm tools, these bearings play a crucial role.
Materials and Construction of 61903 2RS Bearings
61903 2RS bearings are made with care and precision. The main parts are:
- Inner and outer rings
- Ball bearings
- Cage
- Seals
The rings and balls are often made of high-grade steel. This steel is heat-treated for extra strength. The cage, which holds the balls in place, can be made of steel or plastic.
The ‘2RS’ in the name refers to the seals. These are usually made of rubber or a similar material. They keep dirt out and lubricant in. This helps the bearing last longer and work better.
The construction process is very precise. Each part must be made to exact measurements. Even tiny errors can affect how well the bearing works. That’s why quality control is so important in bearing production.
