While both kinds of slide bushings are equally suitable for many applications under normal circumstances, the technology and performance parameters of sintered bushings and polymer bushings differ significantly in part. What are the advantages of bushings made of sintered bronze? And when are polymer bushings more suitable? We will contrast both technologies.
Sintered bushings consist of a sintered bronze body - hence, the name. The main feature of sintered bronze bushings is their porous design, which contains lubricant. Should the viscosity decrease due to increasing operating temperatures due to friction, the oil leaks out. At higher speed, a lubrication wedge develops, which lowers the bushing's friction.
The homogeneous, consistent structure with solid lubricants and reinforcing materials operates without requiring lubrication. This ensures that the solid lubricants incorporated in the material are always available irrespective of the type of movement. Excellent coefficients of friction and wear are given over the entire product life cycle.
Lubrication lower coefficients of friction and enables higher speeds
Limited lubrication impacts linear and pivoting movements
Oil limits resistance to media and temperature stability
Sensitive to edge loads and impacts
Dirt can clog pores
No additional lubrication necessary
Long service life and low coefficients of friction regardless of motion type
High chemical and temperature resistance
Resistant to dirt
Enables the use of low-cost "soft" shafts
In order to ensure smooth and uninterrupted production process, the calibration basket of the machine must be cleaned at regular intervals. In most cases, modern high-pressure cleaners are used. In solutions with conventional bearings, this procedure washes the lubricant out of the plain bearings or even flushes particles of dirt in. This causes problems in the form of downtime which results in additional costs. To solve this problem, iglidur® plain bearings, which are self-lubricating, are now used.
