NORGLIDE® SMTL Bearings
The bronze stretched metal is separately precompressed and the PTFE compound tape is thinner, providing for improved load capabilities while reducing tolerance compensation.
NORGLIDE® SMTL is a composite material of compounded PTFE, bronze stretched metal and steel backing. In contrast to NORGLIDE® SM, the bronze stretched metal in NORGLIDE® SMTL is separately precompressed and the PTFE compound tape is thinner, which improves load capabilities while reducing tolerance compensation compared to NORGLIDE® SM. Bearings of 0.75 mm of wall thickness or bigger can be produced with an interference fit in the housing. Various methods are available to protect the steel shell from corrosion.
These bearings can also be designed without play. Bearings of 1 mm of wall thickness or greater can be produced with an interference fit in the housing. Various methods are available to protect the steel shell from corrosion.
The standard PTFE compound contains either EKONOL® graphite or carbon and graphite. Special PTFE compounds are available on request. Fabricated parts include die-cuts, rolled cylinders, flanged cylinders and deep-drawn bearings.
