RNU 304

Design Features of RNU 304 Bearing

RNU 304 Bearing includes a single row of cylindrical rollers that offer high radial load capacity and efficient performance. RNU 304 outer dia is 52 mm. Its outer dia tolerance is -0.013mm to 0. By eliminating the inner ring, the bearing allows for direct mounting on the shaft, reducing overall weight and enabling a more compact and lightweight design, ideal for applications with space and weight constraints.

 

What Benefits Can RNU 304 Bearing Provide?

  • Space Efficiency: The absence of an inner ring allows for a more compact design, saving space in machinery.
  • Lightweight Design: Eliminating the inner ring reduces the overall weight of the bearing.
  • Direct Shaft Mounting: Can be mounted directly onto the shaft, simplifying installation.
  • High Radial Load Capacity: Supports heavy radial loads effectively.
  • Cost Savings: Fewer components result in lower material costs.
  • Customizable Shaft Surface: The shaft can be customized to meet specific application requirements, offering greater flexibility.

 

What Can RNU 304 Bearing Be Used for?

  • Industrial Machinery: Used in gearboxes, compressors, and pumps where compactness and direct mounting are essential.
  • Automotive Industry: Applied in engines, transmissions, and axles for efficient load support with minimal space requirements.
  • Single Row Equipment: Suitable for cranes and excavators where weight and space constraints are critical.
  • Electric Motors: Provides reliable radial load support while simplifying the motor’s design.
  • Agricultural Machinery: Used in tractors, harvesters, and other equipment requiring durable and space-saving solutions.
  • Material Handling: Ideal for conveyors, hoists, and other systems needing compact and lightweight bearings.
