Product Description

Bronze Sleeve Bushings

While VIIPLUS is recognized as the supplier in pipe handling self-lubricating bearing manufacturing equipment, our sliding bearing bushing product range includes equipment for a wide variety of customers.


Dimensions and Tolerances Metal-Polymer Low Friction Plain Flange Bearings & Cylindrical Bushes materials offer the following characteristics: • Good frictional properties with negligible stick-slip • High static and dynamic load capacity • Suitable for rotating, oscillating, reciprocating and sliding movements • Compact size and low weight • Prefinished that requires no machining after assembly • Possibility to burnish for reduced operating clearance.


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 forms available in standard dimensions,Lead free in compliance with European RoHS

Sleeve Bushing PV Factor:The useful operating life of a red ptfe sleeve bushing & sliding bearing is governed by the pv factor, the product of
the specific load p [MPa] and the sliding speed v [m/s].For thrust washers and flanged bush thrust faces the rubbing velocity at the mean diameter is used.

Bushing Tolerances for minimum clearance Where it is required to keep the variation of assembled clearance to a minimum, closer tolerances can be specified towards the upper end of the journal tolerance and the lower end of the housing tolerance.


Boundary Lubrication Bearings Characterised by:

• Rubbing of the shaft against the bearing
with virtually no lubricant separating the
two surfaces.
• Bearing material selection is critical to
• Shaft wear is likely due to contact
between bearing and shaft.
• The excellent properties of RED PTFE BUSHING material
minimises wear under these conditions.
• The dynamic coefficient of friction with RED PTFE is typically 0.05 to 0.3 u

Given the performance characteristics in
both dry and lubricated operating conditions, RED PTFE and RED PTFE bearing materials are extensively used in a wide range of automotive and industrial applications, such as:
Braking systems, clutches, gearbox and transmissions, hinges - door bonnet and
boot, convertible roof tops, pedal systems, pumps - axial, radial, gear and vane, seat
mechanisms, steering systems, struts and shock absorbers, wiper systems.
Aerospace, agricultural, construction equipment, food and beverage, marine,
material handling, office equipment, packaging equipment, pneumatic and
hydraulic cylinders, railroad and tramways, textile machinery, valves.
