Dryslide TH Sleeve Bushings
TH Series sleeve bushings has a composite structure consisting of a carbon steel backing, an intermediate layer of sintered bronze and a PTFE based sliding lining. Available in inch and metric sizes.
Competitors equivalents: DU, PAPZ-P10, PGZ, PC-Z
The Dryslide trademark identifies a whole range of self-lubricated dry sliding bushings and bearings. A composite structure, TH bushings consists of a carbon steel backing, an intermediate layer of sintered bronze, PTFE/fibre mixture sliding lining. The main items in the TH range are the wrapped cylindrical bushings (DIN 1494) and the flanged cylindrical bushings. Moreover, the range also includes thrust washers, strips and special parts made to customer specifications. From a technical point of view, the product is already widely known and new applications are constantly being identified to take advantage of the high load capacity, the self-lubricated feature and the excellent ratio between cost and performance of the whole range.
The TH sleeve bushing is suitable for dry running applications. It possesses good wear properties as well as a low coefficient of friction that will extend the life of your application. It can be used in both rotary and oscillating applications. Other features include high chemical resistance, low water absorption and swelling. The TH bushing will also perform well with lubrication.
Steel bronze powder with PTFE/Fibres mixture
1. PTFE fibres mixture 0.01-0.03mm, lead free: provides an excellent initial transfer film, which effectively coats the mating surface of the bearing assembly, forming an oxide type solid lubricant film.
2. Sintered bronze powder 0.20-0.35mm: provides maximum thermal conductivity away from the bearing surface, also serves Dryslide structural detailas a reservoir for the PTFE-lead mixture.
3. Low-Carbon Steel: provides exceptionally high load carrying capacity.
4. Zinc/Tin plating 0.002mm: provides good corrosion resistance
A dry running bearing with a low coefficient of friction, good wear properties and sliding characteristics. It can be used in both rotary and oscillating applications
TH Sleeve Bushings Can meet the demanding criteria for long life and trouble-free performance with or without lubrication.
