Home parts for wheelchairs, specifically the wheel bearings, are
crucial components that ensure smooth and reliable operation. These
bearings are often made from high-quality materials such as bronze,
which provides excellent durability and wear resistance. Bronze
bushings, commonly used in medical equipment, are also a key part
of ensuring precision and longevity in these critical applications.
By utilizing these precision-engineered parts, wheelchairs and
other medical equipment can offer a safer and more comfortable
experience for users.
Our PTFE lined wrapped bearings have been developed for high duty, oil
lubricate applications.
Such applications include, but are not limited to:
Wheelchairs & Accessories - Medical Equipment
Our VIIPLUS range of PTFE lined wrapped bearings is suitable for dry running, low friction,
low wear applications. These wrapped bearings have excellent
sliding characteristics forming a transfer film that can protect
the mating metal surface.
We are able to offer PTFE lined wrapped bearings in metric plain, imperial plain, metric
flanged, metric washers, imperial washers, metric strip and
imperial strip.
Special sizes can be produced to customer requirements.

VSB-10 Metal-Polymer Anti-Friction Plain Bearings
ROLLED DRY SLIDING BEARINGS (PTFE)
Steel + Bronze Powder + PTFE/Fibre
Wrapped PTFE Lined (maintenance-free), self lubricated plain or
flanged bearings, thrust washer and strip, Carbon steel shell with
sintered bronze layer filled with PTFE Oilless PTFE bush bushing
VSB-10 Self-Lubricating Multilayer Composite Bushing
Material is designed to operate without supplemental lubrication
and will perform excellent when lubrication is present. Low
friction, low wear rate, good sliding characteristics and very low
absorption are a few of the features of this material. VSB-10
bushings will support rotary, linear and oscillating motion.
