SB bearing (complying with ISO3547 and DIN1494 )

SB bearing is a kind of self-lubricating composite sliding bearing. Due to its compactly structured bearing material (steel/bronze/ptfe), the bearing not only has the advantages of many conventionally lubricated, metallic sliding bearing (particularly high load capacity and dimensional rigidity), but also has advantages like, oil-free, maintenance-free, dry operation, cost saving, consequently the bearing has a broad application range.
Material structure

PTFE lining serves as solid lubricant which is gradually transferred to the shaft during running and self-lubrication is achieved this way. 

 

Sintered porous bronze acts as a bond between steel backing and PTFE lining, it reserves PTFE compound and conduct heat away from the sliding surface.

 

Steel backing provides high load carrying capacity, excellent heat dissipation. ( bronze & stainless steel backing are also available)

Features Main applications

Maintenance-free operation

High load capacity

Wide operation temperature range

Negligible stick-slip effect

Very good frictional properties

Suiting rotating and oscillating in both rotational and axial directions

Hydraulics and valves  

Electric appliances

Manual and electric tool

Material handling equipment

Medical and dental equipment

Automobile,agricultural, construction and off-highway equipment
