VSB-40 Metal-Polymer Low Friction Plain Bearings
viiplus provides a complete set of sliding bearing solutions for hydraulic system users. The supplied products include: gear pump aluminum seat assembly, axle sleeve, side plate; Blade pump and plunger pump with oil plate, return disk, axle sleeve; Cylinder liner and so on.
VSB-40 DP4 low friction bushings offer good wear and low friction performance over a wide range of loads, speeds and temperatures in dry running conditions
· Very good performance in lubricated applications
· Good performance in greased applications
· Suitable for linear, oscillating and rotating movements
Suitable for dry running, low coefficient of friction, lower wear, good sliding characteristics, the transfer film created can protect the mating metal surfaces, suitable for rotating and oscillating movement, high chemical resistance, low absorption of water and swelling. The VSV-40 improved the friction and much good wear resistance over the common CSB-10 range under lubricated operation.

It is a maintenance-free material due to the PTFE sliding layer. Outstanding sliding and wear performance. High load capacity and very versatile bushing.Extended performance due to the bronze backing.
RANGE OF APPLICATION
hydraulic cylinders, cranes and construction machinery, all sorts of production machinery, pumps and medial devices
It is maintenance-free with a PTFE sliding layer. It is not necessary to lubricate this material, but basically possible!
Chamfer min. 1.5 mm x 15-45°, for easy bushing alignment
Chamfer 5 mm x 15°, for easy insertion of the shaft
We advises to use a force fitting mandrel for the installation of the bushing. It might be necessary to apply some grease on the outer surface of the bushing when press fitting it into the housing.
Adhesive should not contact the sliding surface!
1. PTFE/Polymer fibres mixture thickness 0.01~0.03mm. Lead-free bearing layer provides an excellent initial transfer film, which effectively coats the mating surfaces of the bearing assembly, forming an oxide type solid lubricant film.
2. Sintered bronze powder thickness 0.20-0.35mm, provides max. thermal conductivity away from the bearing surface, also serves as a reservoir for the PTFE mixture.
Metric bearings and imperial bushings made to order: Standard bushing forms in special sizes, half-bushings, stamped/deep drawn shapes, bearings with locating notches, lubricant holes and grooves, customized designs
BUSHINGS SIZEVSB-40 is developed for high duty, oil lubricated, hydraulic applications...Automotivesuspensionstruts,absorbers guide bushing, hydraulic cylinders, gear pumps, motors, axial and radial piston pumps & motors.VSB-40 is designed mainly for using under lubricated conditions and it performs excellent wear resistance and low static/dynamic shockfriction coefficient.
