Timken Split Roller Bearings - Savings & Benefits

We often get asked a few questions in relation to split roller bearings – how are they made, how do they work and what is the technology behind them? What are the key benefits? How do they deliver savings? So here, we provide our answers.

Used primarily in demanding applications in arduous conditions where accessible inspection and easy maintenance is a necessity, split bearings have been commercially available for approximately 90 years.

They are made of inner and outer races, a cage, housing and support – all of which are separate. This allows for simple inspection and easy replacement, without the need to remove the bearing from the shaft.

Manufactured as complete parts, the components are accurately cut into two sections following grinding, so that when they are assembled around the shaft, they are perfectly matched.

With a parallel level of performance of that of a comparable sized solid roller bearing, the complete range of split roller bearings incorporates a number of innovative features, assisting both in performance and maintenance engineering.

 

Key Benefits

  • High radial load and speed capability offering life and performance advantages
  • Initially self-aligning minimising expensive alignment of other equipment
  • Large range of standard supports to accommodate mounting solutions
  • Flexible sealing arrangements extending bearing life in harsh environments
  • Interchangeability – each sub-assembly (support, housing and bearing) is universally interchangeable
  • New Single Piece Cage Clip design offering accurate cage alignment and free-hands whilst assembling
  • Pry Slots on all dowelled machined joints for easy separation of the housing and support
  • Intuitive assembly made easy by match markings to ensure correct positioning and orientation of all parts
