Predictive Maintenance
31 Oct 2017
For Asset Optimization.
Predictive maintenance PdM aims to find measures of machinery condition and use them to prevent breakdowns. Establishing trends allow accurate pinpointing of machinery problems and their severity. Increasing up time on machines is the primary aim, while reduced likelihood of secondary failures and less unnecessary maintenance are additional benefits.
Oil Analysis
31 Oct 2017
Oil analysis is a cost effective method for determining the condition of existing lubricants and hence, predicting remaining service life.
Mechanical Equipment Refurbishment Service
31 Oct 2017
BSC Engineering Services can provide bearing refurbishment services which could save you thousands compared to a new bearing, particularly if lead times are longer than required for large or specialized bearings.
Laser Alignment
31 Oct 2017
Mis-alignment in mechanical systems such as motor/pump assemblies is a major factor in increased wear and premature failures.
Balancing
31 Oct 2017
Unbalanced fans, pumps and rotors place undue stresses and additional loads on bearings, motors and couplings substantially reducing component service life, and potentially causing a catastrophic failure which can damage surrounding equipment and harm employees.
Consulting and Design
31 Oct 2017
BSC can provide engineering consulting services for upgrades and new equipment designs.
Energy Audit Service
31 Oct 2017
Energy consumption can be reduced up to 40% by analysing inefficient and poorly designed drives and adopting good drive design practices.
Infrared Thermography

BSC has extensive experience of working with numerous companies in the packaging industry across Australia. Our experience enables us to understand the special needs that relate specifically to your business and production processes.
Vibration Analysis
12 Nov 2017
This is the predominant technology employed in condition monitoring to determine the condition of various mechanical components and hence be able to make a prediction on service life expectancy and urgency of repairs.
It is a non-invasive technique which collects vibration data from machines under normal operating conditions. Vibration readings are typically taken at bearing locations following accepted industry practices and conventions.
This raw waveform data is then transformed into a spectral format and analyzed with proprietary software which allows analysis to take place.
Training
12 Nov 2017
Through a continuous commitment to quality BSC strives to provide solutions for industry.
Utilising our technical expertise we have developed comprehensive product training programs. For the engineer seeking assistance with selecting the appropriate materials or components, a distributor who wants to provide the best available advice and products to your customers, or a maintenance person interested in getting the maximum uptime and performance from your equipment, BSC can help.
Our training program can be tailored to your audience and delivered at your site. Where no standard training program exists to address your needs, we have the experts who can tailor a program just for you.
Stop Leak
12 Nov 2017
Air leaks are one of the biggest contributors to needless costs in any industrial plant/facility.
A leak is a costly drain on overall operating costs. State-of-the-art ultrasonic equipment is used to identify air leaks.
The “Stop Leak” Process is the first step in continuous improvement. Every identifiable leak, including fittings, valves, flanges and hoses are tagged with a number, its location, severity and cost.
Specialist Installation Services
12 Nov 2017
Did you know that only 10% of bearings reach their design service life in the real world!
A major source of failure is incorrect handling and fitting procedures. BSC Engineering Services can provide supervision and assistance with bearing fitting, v-belt tensioning, coupling and roll alignments, and other installation work. Ensuring components are installed correctly to manufacturers specifications provides your site with the best opportunity of maximizing service life and reducing unnecessary down time and production losses.
Article - Cam Follower Bearings

Cam Follower Bearings
Author - Sam Houston Regional Manager SA/NT
BSC have supplied cam followers (also known as track roller bearings) to Australian industry for over 50 years. As is the case with most of our products, technology is not standing still.
BSC’s supply partner the Schaeffler Group (INA/FAG), is a world leading manufacturer of this range and continue to engineer design improvements that enhance performance and maintenance considerations that benefit our customers.
Cam followers are rolling bearings with certain modifications which allow their outer rings to travel along a flat or curved counter raceway. They have been used in many industrial designs for more than half a century.
Cam followers or track rollers can be split into two groups:
- Yoke type
- Stud type
This allows flexibility of choice depending on design requirements.
The most prominent distinction between a standard roller bearing and a cam follower is the execution of the outer ring. Cam followers feature an outer ring which has an enlarged cross section compared to standard bearings. This allows the outer ring to cope with increased bending stresses and associated deformation of the outer ring when the cam follower is running on straight or curved tracks.
The deformation results in a reduced contact zone between rolling elements and raceways. This is taken into account in load ratings stated in respective catalogues. (values Crw and C0rw).
Another important feature is the profiled outer diameter of the outer ring. It reduces the extent of edge loading when cam followers are not perfectly aligned with the mating straight or curved track. Industry standard has been for many years to apply a profile radius of approx. 500 mm.
Misalignment between cam follower and track.
Stress reduction with profiled outer ring.
Latest X-life technology from the Schaeffler Group (INA/FAG) reduces acting stress even more. An optimised profile has been made available for various series of cam followers.
At first glance, the benefit may be reduced fatigue and wear on the cam follower only. However, the mating track will also be subjected to lower stresses and less wear. Particularly long tracks, as well as elaborate cam profiles, can be very costly to replace or to refurbish. Thus considerable cost savings during the machine life are achieved when utilising cam followers with optimised profile.
Stud type cam followers feature hexagonal sockets (except sizes 16 and 19, which feature slots) to accommodate allen keys during the mounting of the nut. Stud type cam followers are generally supplied with a nut suiting the threaded stud end.
Relubrication choices of a stud type cam follower. Inside the hexagonal sockets are lubrication bores for re-lubrication. They can be fitted with grease nipples, closing plugs or central lubrication adapters. One grease nipple, one closing plug and one nut is normally supplied together with the stud type cam follower. | Misaligned cam follower positioning and stud type cam follower with eccentric locking collar. When groups of cam followers are to be used in line to provide support, stud type cam followers with eccentric locking collar are recommended. The eccentric locking collar provides the capability to align all cam followers in such way that they all sit on the track without clearance. These product feature the letter E in the product designation (e.g. KRE19PP). |
The variety of features introduced above leads to a number of different designs of cam followers. Underneath can be seen different series, distinguished between yoke and stud type as well as between ball and roller type.

Stud type cam followers
Summary
Cam followers are versatile machine elements which have proven their capabilities for many decades. The large variety available allows optimal selection for the application concerned.
BSC primarily stock and provide design recommendations on INA brand of Stud and Yoke type cam followers as technology leaders in this series of bearings.
BSC also supply McGill, Smith and RBC range of imperial series cam and roller followers.
