What are sliding door rollers, how are they composed, and which rollers should you use in your sliding door repairs?
Why do we use twin bogie rollers in sliding door repairs?
Today’s sliding doors have thicker glass, and multi-stacking sliding doors are becoming common. This means more significant weight and strain on the rollers supporting these doors.
It has been seen in our door repairs: Sydney requires more maintenance in its newer sliding doors, while older sliding doors are serviced every 15-25 years.
It is now common in sliding door repairs; Sydney’s newer types of doors require rollers with greater carry-load capacities, and twin bogies rollers are preferred.
Twin bogie rollers give sliding doors another set of rollers in bogies, resulting in much smoother use and longer life between services.
We prefer twin bogies rollers for sliding doors, so we primarily use them for door repairs.
What are twin bogie rollers?
We mainly utilise twin bogie rollers for our sliding door repairs in Sydney due to their additional pair of rollers and the bogie suspension system they’re mounted on. This setup enables all four rollers to contact the track, evenly distributing the door’s weight.
The twin bogie roller system incorporated in our door repairs features a pair of rollers housed within a cassette. This cassette is connected to a differential joint or pivot point on the carriage, allowing the rollers to rock on this pivot point.
Acetal Delrin in twin bogie rollers
We use Acetal Delrin rollers, not nylon rollers, in our sliding door repairs. Acetal Delrin rollers are preferred for their superior tensile strength, stiffness, low friction, and wear resistance.
Twin bogie rollers consist of Acetal Delrin and stainless steel. Acetal Delrin plastics are engineering thermal plastics used in precision parts.
What are all the parts of a roller, and how do they work?
- Sliding door rollers in door repairs consist of two main parts: the roller and the carriage.
- The standard roller consists of an axel, bearings, and tire.
- What constitutes the standard carriage is the cassette and the carriage itself.
- If the carriage is adjustable, it will include the cassette.
- The roller will sit inside the cassette, and the cassette will sit inside the carriage.
- The adjustment fastener connects the cassette and carriage. This fastener adjusts the position of the roller in the carriage and, therefore, raises or lowers the ends of the sliding door.
- If the roller does not have an adjustment mechanism, there will generally be no cassette or adjustment fastener. The roller will attach directly to the carriage, so the sliding door cannot be adjusted.
- Sometimes, there are adjustment positions on the carriage, where the roller is removed and installed into these different adjustment positions. These are straightforward rollers.
What are Single rollers?
There are three different types of rollers in roller mechanisms. The most common are single rollers, which the larger hardware stores usually stock.
Single rollers consist of one roller that sits inside its carriage. Singles rollers can be adjustable via the adjustment fasteners or by adjustment positions on the carriage.
What are Double rollers?
Double rollers seen in roller mechanisms illustrate two rollers per carriage. However, these rollers are fixed, so only two of the four rollers will contact the track. This defeats the purpose of having an extra set of rollers on the door.
There are other systems like double rollers where the rollers have a minimal range of motion or do not move properly inside the carriage. Some of these systems may look good; unfortunately, they also defeat the purpose of having extra rollers on the door.
