Pneumatic Industries Bushings Pump Bushing Of Cylinder Guide Sleeve
1. Product Description
Pneumatic Industries Bushings Pump Bushing Of Cylinder Guide Sleeve is made of high quality low-carbon steel with sintering porous bronze as its interlayer and the compound of wear-resistant. It is suitable for rotary and oscillating movement,lower mainterance requirements due to the long re-lubrication intervals,lower wear susceptibility to edge loading,no absorption of water and therefore no swelling,good damping behaviours,good resistanceto shock loads.
2. Specification
| Load capacity | Static load | 250N/mm2 | Friction coef μ | 0.05~0.25 |
| Dymamic load | 140N/mm2 | Working temperature | -40℃~+130℃ | |
| Oscillating | 70N/mm2 | Themal conductivity | 13W/mk | |
| PV value limit | Oil lubrication | 22N/mm2.m/s | Speed limit (in oil) | 2.5m/s |
| Dry friction | 2.8N/mm2.m/s | Coefficient of linearexpansion | 12×10-6/K |
3. Application
Pneumatic Industries Bushings Pump Bushing Of Cylinder Guide Sleeve are widely used in oil cylinder,piston pump ,gear pump ,vane pump etc.
4. Advantages
The products are maintenance-free and used in common hydraulic fluid and many types of water emulsion conditions, suitable for vane pumps, gears, plunger pumps and motors.In addition to their excellent frictional and anti-wear properties, they are stable and reliable under required loads and speeds, making them suitable for many hydrodynamic applications.Steel Backed Bushing provides superior shock and impact load resistance. The Steel Backed PTFE Lined bushing maintains a low coefficient of friction and is usable without lubrication at high load, low speed operations with excellent wear resistance.It can substitute a conventional bearing where saving space is desired.
