Product Details

A drawn cup needle roller bearing is a type of rolling element bearing that utilizes cylindrical rollers with a small diameter and a length much larger than their diameter. These bearings are designed to provide high radial load-carrying capacity within a compact and lightweight design. Drawn cup needle roller bearings are commonly used in applications where space is limited and a high load-carrying capacity is required.

Key features and components of drawn cup needle roller bearings include:

Outer Shell (Cup): The outer shell, often referred to as the "cup," is typically made from stamped sheet metal and serves as the outer raceway for the rollers. It provides support and guidance for the rollers as they move within the bearing.

Needle Rollers: The cylindrical rollers are referred to as "needle rollers." These rollers have a small diameter, allowing them to fit within tight spaces, while their length provides a larger contact surface for distributing loads. Needle rollers are used to transmit radial loads.

Cage: Many drawn cup needle roller bearings include a cage or separator that keeps the needle rollers evenly spaced and prevents them from coming into direct contact with each other. The cage also helps to reduce friction and wear.

Seals and Lubrication: Some drawn cup needle roller bearings may include integral seals to protect against contaminants and retain lubrication. Lubrication is essential to reduce friction and wear, ensuring the bearing's smooth operation.

Drawn cup needle roller bearings find application in a wide range of industries and equipment, including:

Automotive components such as transmissions, powertrain systems, and wheel hubs.

Industrial machinery, including textile machines, printing presses, and conveyor systems.

Agricultural equipment like tractors, harvesters, and balers.

Appliances such as washing machines, refrigerators, and air conditioners.

Office equipment like photocopiers and printers.

Due to their compact design, drawn cup needle roller bearings are particularly suitable for applications where space constraints are a concern. They offer a cost-effective solution for high-load, low-speed, and oscillating motion requirements. However, it's important to note that they may have limitations in terms of their ability to handle axial loads or high-speed applications, as compared to other types of bearings.
