D-glide® composite bearing material
What is D-glide®?
Our specially developed D-glide® composite bearing material is our flagship product, something we are very proud of.
D-glide® is a composite bearing material made from the latest generation of synthetic fibres, thermoset vinyl ester resin, solid lubricants and additives. It is a non-metallic material, offering high strength combined with a high amount of elasticity, also known as FRP or Fibre Reinforced Plastic. The resin systems have good chemical resistance, do not swell in (sea)water and are insensitive to aging. Friction modifiers such as PTFE are incorporated to minimize friction and maximize wear resistance.
DRIE-D has an experienced and enthusiastic team of engineers who develop tailor-made bearing solutions for every possible movement challenge, whereby the properties of our D-glide® composite material are used in the most optimal way.
Material characteristics D-glide® composite
Unlike traditional bearing materials, such as bronze or steel, D-glide® is not a metal, but a synthetic composite material. This makes the behavior of D-glide® bearings very different, both mechanically and in terms of sliding properties.
The load capacity of D-glide® is comparable to the better metal bearings. Because D-glide® is more elastic than metals, the forces are distributed more evenly, reducing the maximum Hertzian stresses in the material. This also allows the use of D-glide® bearings in applications where large deformation or misalignment is required.
Because the material does not contain metal, D-glide® cannot corrode, cause corrosion, cannot cold weld to a mating surface, nor cause surface fatigue.
In addition, D-glide® bearings can be used maintenance-free, unlubricated. This is not only good for the environment, it also minimizes operating costs and delivers major advantages in reliability. D-glide® gets the lubrication out of its own material, so extra lubrication is not necessary and you are no longer dependent on automatic lubrication systems or the performance of set lubrication intervals.
Key features of D-glide® material
Our range of D-glide® materials sets itself apart through the key-features that are listed below.
- High-load capacity
- High Elasticity
- Maintenance-free
- Negligible water absorption
- Low friction
- Extremely wear resistance
Different grades of D-glide® composite bearing material
The D-glide® product line exists out of four different grades. Each grade has its own unique properties, benefits and application limits. We want to give you a short overview of each grade.
- D-glide® FT has a special sliding layer, which is the clearly distinguishable greenish layer. D-glide® FT has the lowest possible friction with minimal difference between static and dynamic friction.
- D-glide® FC has additional additives in the resin that increase the abrasive wear resistance of the material by up to ten times compared to D-glide® F.
- D-glide® F is the standard grade for all dynamic applications and an excellent maintenance free alternative for traditional steel or (self-lubricating) bronze bearings.
- D-glide® P is the base D-glide® grade, suitable for all semi-static applications and an excellent maintenance free alternative for traditional steel or (self-lubricating) bronze bearings.
D-glide® products
We produce different products out of D-glide® composite bearing material for customers all over the world. Whether it is a large custom-made spherical bearing or serial produced standard parts like bushings or wear pads.
Mainly we divide our products in the following four categories:
- Spherical bearings
- Thrust washers
- Bushings
- Wear pads
Engineering with D-glide®
Creating a bearing design from composite material requires a different approach compared to calculating with steel or bronze. In our datasheets you can find an overview of the properties of D-glide®, some values depend on the design and the way in which the material is being used.
With over 25 years of experience in engineering with D-glide®, we have built an impressive track record of challenging projects. At DRIE-D we have a dedicated in-house engineering department, continuously designing with D-glide®.
We are more than willing to share our expertise and to help you make the right choices for your bearing design.
