Increased safety thanks to technical superiority
INA’s track rollers with optimized outside profile are clearly superior to conventional components. Hertzian pressure at the contact point is always lower than with conventional rollers, both with and without tilting. This reduces wear of the mating track and increases the rigidity of the design.
It is when you need to control the ink distribution or the gripper shaft of a sheet offset machine that the track rollers’ many benefits are most evident. They have a very compact and spacesaving design and are characterized by high load capacity, a low level of wear and high reliability. Thanks to their large grease reservoirs, relubrication intervals can be considerably increase, which reduces costs.
The further development of our stud type and yoke type track rollers with needle rollers focused on increasing operational reliability and service life. The result is a new design of the thrust rings and sealing rings made from high-quality plastic.
The Schaeffler Group also has many convenient solutions for extreme environmental conditions, such as in dampeners. For instance, Corrotect® corrosion protection can be applied to track rollers during manufacture. This thin, electroplated layer does not give corrosion a chance to develop and is very economically priced. We also design special track rollers, such as rollers including eccentric studs.
Extremely wear-resistant with TRIONDUR
Track rollers with TRIONDUR coating offer the highest operational safety. The PVD coating is only a few microns thick but extremely hard and protects the track rollers and the cam plates against wear.
TRIONDUR coating systems have a friction coefficient that can be up to 80% lower than in steel-steel combinations. This coating provides durable protection for high tribomechanical stress, insufficient lubrication and dry running.
