Load Capacity, Bearings, Durability, Temperature

Load capacitieskg
The wheels and castors in this catalogue are rated for intermittent use on average floor conditions encountered in most factories and warehouses. The ISO and European Castor Manufacturers (FEM) standards set out to duplicate these conditions of average use and are used by Lemcol as a guide when rating our products.

Bearing descriptions bearing
Tapered Roller
These are the highest capacity bearings, used in Super wheels and castors. They
are fitted with seals to stop ingress of dirt and grit and only require occasional regreasing. They are fitted to axles that require fine pre-load adjustment.
Spherical Roller Bearings
Capacities equal to that of tapered roller bearings, used in high capacity Super castors and wheels. Fitted with seals to stop ingress of dirt and grit and only require occasional regreasing. Used in applications where there is no preload adjustment on the axle (ie. in axle retained by keeper plates).
Precision Ball
These sealed, deep groove ball bearings are “off the shelf”, high quality bearings they are sealed for life and require no maintenance -used in all polyurethane and cast iron wheels, as well as a number of pneumatic wheels.
Double Row Ball Bearings (ORB)
These robust, precision machined, Lemcol designed bearings are used mostly on older model industrial wheels. They are self contained and require regular lubrication.
Roller Bearings
This bearing consists of a caged needle roller running on a case hardened sleeve.
Ball
Unground bearings – usually well shielded but not fully sealed . These bearings are pre-greased and easily replaced. Ideal for medium capacity and low speeds.
Acetal
A plain bearing, acetal polymer bush with oil impregnation. This bearing used in solid rubber wheels is quiet, self lubricating and offers good strength and wear resistance.
Plain
These bearings are the simplest of bearings, formed by the wheel material itself. Generally found in nylon and cast iron wheels, they offer excellent impact resistance. The nylon vesion is self lubricating, but cast iron is most efficient if regularly lubricated.

Durability
Lemcol castor frames are constructed in one of three ways. The construction technique influences factors such as lifetime, strength and cost. Use the following table to select the frame best suited to your needs.

Chemical resistance
Contact with a number of common chemical compounds can severely limit the lifetime of a castor. The following table indicates how each tyre material is affected by common chemicals. Detailed advice on chemical resistance is available upon inquiry.

Finish

Lemcol Super and Industrial castor frames are offered in a distinctive metallic painted finish. The remaining series are offered a zinc coating. Zinc coated frames have proven themselves in the majority of usage situations.
Regular contact with water (and other agents) will cause your castor to corrode. If such contact is likely, we recommend you use the Full Stainless Steel frames offered in selected ranges.
