Choosing bearings for collaborative robotics...

Behind the drawn factory doors of facilities across Europe, humans are working safely alongside a new kind of colleague; one that is stronger, faster and more efficient than ever before: collaborative robots. Here, Chris Johnson, managing director of bearing distributor SMB Bearings Ltd, explains how to choose the right bearing for this new automation application.

Just a few years ago, collaborative robots were widely considered a novelty, but the technology has quickly grown to be one of the most significant trends in robotics. In fact, an ABI Research study predicts that industry will be populated with more than 40,000 collaborative robots by 2020.


As opposed to traditional industrial robots, which are confined to operate in work cells to protect human workers, collaborative robots can operate — as the name suggests — collaboratively with their human counterparts. They are designed to operate safely alongside people, by limiting the robots force and implementing sensors that prevent the robot colliding with a human or any other equipment.

The machines are used to carry out repetitive roles such as assembly and handling, taking these menial tasks away from humans to free them up for more complex tasks. As they are designed to take on these basic operations, collaborative robots tend to be much simpler than other industrial robots, making them cheaper to buy, easier to operate and less hassle to maintain.

Maintaining accuracy
Despite the simplification of their design, the specification of bearings for collaborative robots is just as important a consideration as those of more complex robots, like six-axis or SCARA models. Industrial robots are required to deliver high levels of accuracy and repeatability and collaborative robots are no exception.

Consider the rotary joints of a collaborative robot as an example. Manufacturers expect the robot to deliver smooth actions, with good rotational accuracy and reliability. However, in robotics applications, there is more to choosing a bearing than simply selecting one that fits.

To guarantee the high levels of rotational precision and reliability required for the operations of a collaborative robot, manufacturers should invest in high quality, precision bearings for the robot’s rotary joints.

As distributors of Sapporo Precision of Japan, who manufacturer EZO thin section bearings for robotics applications, we understand how high-quality bearings can prolong the lifespan of industrial equipment. These bearings are lightweight take up much less space than standard bearings and have excellent standards of roundness and surface finish.

Conversely, a poor-quality bearing can result in unexpected downtime caused by inaccurate movement or higher frictional torque creating problems with the robot’s operation. For collaborative robots, any inaccuracies can also create significant health and safety risks for human workers.

Making the most of investments
Naturally, manufacturers investing in collaborative robots are doing so to increase productivity, output and — perhaps most importantly — increase profits in their facility. However, not all manufacturers are aware that incorrect bearings can directly impact the functionality and the longevity of a collaborative robot’s lifespan.

As with any kind of industrial robot, there is no standard bearing that will suit every collaborative robot application. The correct bearing would depend on the environment in which the robot will work and its operations. Manufacturers should speak to a bearing expert for advice on selecting the right bearing specification.  

In 2016, collaborative robots represented just three per cent of all industrial robots sold. However, estimates suggest that collaborative robots will account for 34 per cent of all industrial robots sold by 2025. There has never been a better time to invest in collaborative robots.

For advice on selecting robotics bearings, speak to the bearing experts at SMB Bearings. The team can discuss the exact bearing specifications needed for your application to ensure you make the most of your robot investment.

Roxana Howlett looks back at 2017...



We were delighted to receive an update this week about our friend a all round skate superstar Roxana Howlett, prepared on her behalf by another legend - her Mum Emma 😄

Emma says:
"As 2017 is coming to an end I thought I would drop you a line to thank you for your continued support of Roxana.  It has been a great year for Roxana with skating and she's enjoyed every minute of it.  Below are some of her achievements this year.




  • Battle of Hastings - 7th (out of 22 women)
  • Buckland Jam - 1st in under 8s and Best trick
  • UK Girls Skate Jam -  2nd in under 18s & 3rd in Sponsored
  • Nass - 6th place
  • Exmouth skate jam - 2nd in under 14 mini-ramp
  • Exminster skate jam - 1st in under 13s
  • Dawlish Skate Jam - 1st in under 13 mini-ramp


Roxana has also appeared in an advert skateboarding for Cartoon Network, appeared in the women's skate film Scratch The Surface, been photographed for a skateboarding book, gained new sponsors, and is now represented by Lucy Adams on an Athlete Management Contract".



Well, what can we say apart from a massive "congratulations!!" to this inspirational &
 uber-cool young lady - we're thrilled to have been a part of the skate action with Roxana in 2017 & can't wait to support her & see what she gets up to in 2018!    

In the meantime, check out this brilliant edit which she's shared with us:





You can follow Roxana on Instagram & YouTube & of course we'll proudly feature lots more exciting news about her right here 😃



We're sending you our best wishes for fun & happiness in 2018 Roxana - with love from us all
