Slide-Bushing-1Slide-Bushing-2

PROPERTIES For high operational demands (also impact load), oscillating movements, wear-resistant, unsusceptible to dirt, corrosion resistant, long length of life. Maintenance-free!
MATERIALS Standard material CuZn25Al5* / ASTM C86300
MATERIAL PROPERTIES **
Specific load capacity static ≤ 150
[N/mm²]
Specific load capacity dynamic ≤ 100 [N/mm²]
Sliding speed ≤ 0,3 to 1,0 [ m/s ]
Friction value 0,03 to 0,20 [ µ ] lubricated / dry
Temperature strain -100 to +300 [ C° ]
Max. Pv – value 1,5 [ N/mm² x m/s ]
Hardness 190 – 220 [ HB ]
Solid lubricant share approx. 25-30 [ % ]
TOLERANCE DETAILS
Housing – Ø H7
Bushing after mounting Information after consulting. Delivered bushings with tolerances: r6/E7
Shaft tolerance f7/h6
SHAFT MATERIAL The hardness difference to the bearing should be 100HB at least, preferably hardened and dressed to size, surface roughness < Rz 6,3.
MOUNTING ADVISE
Housing – Ø Mounting bevel, min. 1,5 mm x 15-45°
Shaft Mounting bevel, 5 mm x 15°, edges rounded
Force fitting mandrel The application of an adequate force fitting mandrel is advisable. Grease lubrication of the outer surface may be necessary when mounting.
MAINTENANCE LUB-MET® is a maintenance-free sliding bearing, but primary lubrication is necessary! Therefore a none-ageing lithium stiffened grease should be used.
* As a special design additional sliding alloys are available.
** The above stated material properties are valid for optimal operating conditions. Through changes of the application conditions e.g. higher sliding speed or strain, these values are subject to change.

Slide-Bushing-4

TECHNICAL DATA BRO-LUB®

  • Wrapped bronze sliding bearing.
  • Solid lubricant pockets.
  • Maintenance-free
  • DIN 1494 / ISO 3547
  • All special designs are produced at short notice!
  • Cylindrical bushing, thrust washer and strips are standard fabrication.
PROPERTIES High load capacity and stability at low abrasion, excellent suitable at low sliding speeds and oscillating movements, maintenance-free.
MATERIALS
Support material CuSn8P (DIN 17662) Lubrication pockets are filled with solid lubricant.
MATERIAL PROPERTIES
Specific load capacity static ≤ 120 [ N/mm² ]
Specific load capacity dynamic ≤ 40 [ N/mm² ]
Sliding speed ≤ 2,5 [ m/s ] depending on lubrication
Friction value 0,03 to 0,25 [ µ ] depending on lubrication
Temperature strain -100 to +200 [ °C ]
Max. Pv – value 2,8 [ N/mm² x m/s ]
TOLERANCE DETAILS
Housing – Ø H7
Bushing after mounting H9
Shaft tolerance f7 to f8
SHAFT MATERIAL Steel, hardened or untempered, surface roughness ≤ Rz 6,3
MOUNTING ADVISE
Housing – Ø Mounting bevel, min. 1,5 mm x 15-45°
Shaft Mounting bevel, 5 mm x 15°, edges rounded
Force fitting mandrel The application of an adequate force fitting mandrel is advisable. Maybe grease lubrication of the outer surface is necessary when mounting.
MAINTENANCE BRO-LUB® is a maintenance-free bronzed sliding bearing with solid lubricant pockets, but primary lubrication is necessary! Therefore an ageing resistant lithium stiffened grease should be used.
