METALON PRODUCT FEATURES :
Low co-efficient of friction
With built-in lubricants, there is no need for elaborate lubrication systems.
Water can also be used to lubricate METALON bearings.
High impact and abrasion resistance
METALON bearings can absorb punishing, random high shock loads. With its memory, the bearing returns to its original shape and size, without cracking, deforming, or deteriorating. Long life, low wear
METALON materials are tough and have excellent wear resistance characteristics in any environment: salt,fresh or dirty water.
Bearings made of METALONs, a homogenous, non-metallic material, resist most types of corrosion at the bearing surface and between the bearing and the housing.
- High-pressure capability
METALONs are very versatile materials. You can turn, drill, tap, shape, jig saw, mill all grades.
Outperforms traditional bearing materials
METALONs are tough, non-metallic, synthetic, polymer alloy, which provides exceptional abrasion resistance. Combining this with qualities of flexibility and high load-carrying ability, they can withstand a great amount of abuse in adverse operating environments often found in sleeve bearing applications. In fact, under many severe conditions.
METALON Industrial bush bearings out-perform bronze, Babbitt, Teflon, phenolic and a host of other non-metallic materials in providing longer trouble-free operation.
Because of its exceptionally high impact strength. METALONs possesses unusual ability to absorb shock loads. They performs extremely well under vibration and misalignment conditions.
SHAFT OR MATING SURFACE WEAR
Since METALON tends not to carry abrasives, shaft wear may be reduced when compared to other bearing materials. In making an evaluation, however, shaft wear should be related to length of service. If, for example, an METALON - OILLON bearing outwears extruded nylon by 2:1, a fair comparison of shaft wear would be with the total wear down produced by two nylon bearings. In comparative test, METALON - OILLON has caused less shaft wear than the other METALON grades.
RESISTANCE TO OIL, WATER, SOLVENTS, AND CHEMICALS
METALONs possesses excellent corrosion resistance and resistance to oil, water and chemicals. It is not affected by lubricants normally used with sleeve bearings. METALON absorbs approximately 0.6% water by volume under atmospheric conditions and at a temperature of 23oC. This expansion is gradual and may take up to 4,000 hours to complete, under static conditions. Under dynamic conditions, absorption can occur much faster. The majority of the expansion occurs, however, within the first 1,000 hours. If the pressure or temperature is increased, not only does the volumetric swell percentage increase, but also the rate of absorption. In tests using water at 60oC, the volumetric swell increased to between 1.9% and 2.1% within 100 hours. In practical tests, when hot water is not present, the average bore closure effect of water absorption was 0.022 times the wall thickness. A conservative indication of METLON's behavior in a wide range of chemical environments is available in a “ Chemical Compatibility Chart . In critical situations, testing of METALON before putting bearings in actual operating equipment is recommended, by immersion for 30-60 days, measuring sample dimensions before and after immersion, and also checking hardness. Any significant variance from the METALON standard would indicate possible compatibility problems.
