• Thin wall thickness is the most important peculiarity of Wrapped Bronze Bearings. They are light and compact; The inner-layer of the bush being a kind of high density copper alloy of special compositions, there is no hole and pit and provides higher load capacity and fatigue strength, in compare with traditional casting bronze bushes. • It is manufactured by advanced technology and machines, various kinds of lubricating indentations or grooves may be readily provided on the sliding surface, and so the re-oiling period is remarkably prolonged and the service lift is accordingly prolonged.
• It’s used in agricultural machinery, construction machinery as well as engineering machinery etc. |
Properties |
High load capacity and stability at low abrasion, excellent suitable at low sliding speeds and oscillating movements. |
Materials |
Support material | • CuSn8P (DIN 17662) |
• CuSn10Pb10 (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-Inner - Ø after mounting | H9 |
Shaft tolerance | f7 |
Shaft material |
Steel, hardened or untempered, surface roughness ≤ Rz 6,3 |
Mounting advise |
Body drill | 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 |
CLI-FB wrapped bronze slinding bearing 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. |
