Our Bearing Services

Bearing Remanufacturing

Bearing remanufacture is proving to be a reliable solution for reducing costs and CO2 impact. ACORN offers a remanufacturing service where any brand of bearing can be restored to like-new condition.

This service is ideal for larger bearings or bearings used in high quantities.

Remanufacturing is also extremely useful in situations where long lead times are expected on new bearings. 

Bearing & Housing Modification

Bearing modification can enhance bearing performance, reliability, and longevity, making them better suited to the demands and requirements of a specific application.

Utilising ACORN's experience, we can offer many variants depending on your requirements.

Typical bearing modifications include circlip grooves, a tapered bore, clearance changes, lubrication grooves, spacer manufacture for pre-defined preload, anti-rotation notches, bore, outside diameter and width adjustments. 

Typical housing modifications available include various machining, drilling, tapping, coating and painting. 

Bearing Relubrication

Due to availability or demand, getting the desired lubricant with your chosen bearing is not always possible.

To ensure you always have the optimum product for your application, ACORN offers a bearing relubrication service.

Simply specify your preferred lubricant and bearing, and our experienced team will do the rest, providing a finished bearing with the correct grease fill and grease supplied. 

Bearing Installation

Bearing fitting is not always the most straightforward job, even with the arsenal of tools and equipment available to end users.

Incorrect fitting can cause bearings to fail prematurely, leading to unplanned downtime and lost production.  

ACORN can ensure your bearings are removed and fitted correctly, minimising shaft damage and maximising bearing life.

Our skilled engineers use correct mounting and dismounting equipment and procedures to safely remove existing bearings and install new ones. 

Lifetime Calculations

Many businesses utilise manufacturer calculation software but struggle to interpret the data received. ACORN can help create and interpret lifetime calculations and identify potential project success or failure.

We can also provide unbiased application support, specifying the most appropriate products after considering the environment and application requirements. 

Product Cross Referencing

Stock rationalisation and reduction are great ways to see instant results and save money and time in the long run. 

ACORN can help you cross-reference an OEM part number on your production line to an equivalent bearing of the same or higher quality—often saving you considerable money.

We can also identify that unmarked bearing on your machine and offer a recognised premium brand replacement, which could increase machine uptime. 

Production Line Mapping

Many bearings are fitted to production lines without considering the application or the environment in which they will operate, whether hot, cold, wet, or dusty.

Due to incorrect conditions, these bearings could fail much earlier than their expected lifespan. Multiply this by the number of bearings on your production line and the amount of unplanned downtime and maintenance man-hours, and the costs mount up. 

By performing a start-to-finish map of your production line, reviewing the bearing applications in sequence, and suggesting if each is suitable for use or if an improvement can be made ACORN can help reduce your downtime. 

Application Review

If you already know you are having application problems with a specific bearing, ACORN can help.

Our experts have years of industry experience and are armed with the latest product technology from premium bearing manufacturers.

Upon visiting your site, they would gather the relevant application details and offer solutions based on their findings. 

Failure Analysis

If you have a repeating bearing failure, don’t throw the failed bearing away.

Send it to Acorn, and our team of bearing experts will be able to correctly open the bearing and read the cause of failure.

Correctly identifying the cause of failure can then help suggest the correct solution to increase uptime and reduce overall costs.

Bearing services examples

Lifetime Calculation

Acorn Industrial Service was requested to comment on the lifetime of 6206, 6308, 6211, and 6311 2RS1 sealed with WT-type grease lubrication for a Centrifugal Pump application. 

  • Andrew Fletcher of Acorn used the SKF Bearing Select online calculation tool to calculate the theoretical lifetime for 4 bearings and then provided discussions and conclusions for the customer.

Production Line Mapping

Acorn Industrial Services was requested by a leading food manufacturer to conduct a Process Line Mapping exercise. The customer knowingly had issues on a production line and was requesting support to help improve uptime. It was believed that bearings were contributing to 50% of site downtime. The main issues usually associated with this type of production line are the wet and washdown environments.

  • Acorn concluded they would benefit the most from using a Solution-based product, such as the SKF Foodline range.
  • Standardising on a premium brand of bearing on the line would help to improve bearing lifetime by increasing part reliability through material/manufacturing methods
  • Utilising auto lubricators in the often-forgotten applications will ensure every bearing maintains the correct lubrication at all times

Failure Analysis

Acorn Industrial services were requested by a customer to investigate the route cause failure of a single SKF brand 22222 EK double-row spherical roller bearing. The bearing was for an unknown application and end user. Furthermore, there is no information as to what the applied load or running speed was on the bearing

  • There was damage to multiple spherical rolling elements, the inner ring and the outer ring which can all be categorised as Brinelling Indentations
  • Acorn suggests ensuring that the inner ring and outer ring are correctly aligned during the installation process to avoid future Brinelling Indentation damage

Lubrication System

Acorn Industrial services were requested by a large construction customer to support in analysis of a problematic lubrication system. The system was installed on a Hitachi Excavator and is used to lubricate various points along the arm. The system isn’t working as it should be with grease purge visible near the pump and bearings regularly running ‘dry’.

  • The lubrication system problems are due to a thick grease being pumped over a significant distance
  • Acorn suggested trialling SKF LGLS 0 grease which is much more viscous and will offer improved pumpability to help reach the required grease points
