David from CanadaOur company import the bronze gleitlager from viiplus china,viiplus professional team makes sure customs clearance is always smooth. They provide an accurate bronze bushing classification, handle all the paperwork,We have received the self-lubricating bronze bushings. They look well done and the high quality.
Valerie from CaliforniaWe import the bronze gleitlager from China to under the incoterm FOB shanghai, sometimes by Air. viiplus is a very good bronze gleitlager supplier, they are very professional and patient, after we inform the new order, they will manufacturer bronze gleitlager in time and give us the schedule , and then we just need to receive the bronze parts
Daisy From GermanyThe best surface finishes for Sleeve Bearing, tighter concentricity, and bronze bushings material uniformity. The good supplier of standard inch and metric sleeve bearings and bushings from china.

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
• 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
These bushings are manufactured to International,National or standards. Thefollowing components are standard stock products:
• Cylindrical Bushes
• Flanged Bushes
• Thrust Washers
• Flanged Washers
• Strip Material
Non-Standard Components,These seevess are manufactured to customer's requirements and include forexample:
• Modified Standard Components
• Half Bearings
• Flat Components
• Deep Drawn Parts

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.
