Bespoke Units

Alwayse has decades of experience in the Research & Development of Ball Transfer Units (also know as Ball Castors, Ball Rollers or Roller Bearings). When required a new ball unit can be designed and manufactured in-house to match your specific requirements. Please contact our experts to discuss your particular requirements.

As manufacturers of the world's widest range of ball units, we have existing units that are suitable for most applications. However, if requirements cannot be met with an existing unit, bespoke units can be made to match a range of non-standard criteria.
