Needle Roller and Cage Assemblies – Compact, High-Load Bearing Solutions

Based in the UK but serving a global market, Bolton Engineering Products Ltd are leading needle roller and cage assembly stockists and have been for many years.

Our range of needle roller and cage assemblies offer increased load carrying capacity, better rigidity, and are suitable to applications that have high weight and space limitations.

The bearings are supplied with a precision seating surface enabling strength and stability of the bearing in operation resulting in flow-line roller seating surfaces.,There are no complex race seating or chaffing problems.

What Are Needle Roller and Cage Bearings?

Needle roller cages (also known as caged roller bearings) contain long, thin cylindrical rollers arranged in a cage that maintains equal spacing and alignment.
This design allows for high-speed rotation, low friction, and superior load handling despite their compact cross-section.

They are often used in:

  • Automotive transmissions and gearboxes
  • Machine tools and agricultural machinery
  • Compressors, pumps, and motors
  • Aerospace and robotics applications

FAQs

Q1: What is a needle roller and cage assembly?

It’s a bearing that uses cylindrical needle rollers contained in a cage (retainer) to minimize friction and allow high-speed rotation without using a full inner or outer race.

Q2: What are the advantages of needle cage bearings?

They offer high load capacity, rigidity, and compact design, making them perfect for limited-space applications.

Q3: Are these bearings suitable for high-speed applications?

Yes, caged roller bearings are ideal for high-speed and high-precision applications where reliability is crucial.

Q4: Do you stock different cage materials?

Yes, BEP Ltd offers steel, brass, and polyamide cages, depending on your application requirements.
