定义
A precision mechanical component designed to support the rotating shaft within an agitator head assembly, maintaining proper alignment while minimizing friction and wear. It consists of either rolling-element bearings (ball or roller) or plain bushings (sleeve bearings) that interface between the shaft and housing, handling radial loads and ensuring smooth rotational motion in mixing applications.
工作原理
Operates on the principle of reducing friction through either rolling contact (bearings with balls/rollers) or hydrodynamic lubrication (bushings). In agitator applications, it supports the shaft against radial forces generated by mixing action, maintaining concentricity while allowing free rotation with minimal energy loss.
材料
Bearings: Chrome steel (AISI 52100)stainless steel (AISI 440C)ceramic hybrids. Bushings: Bronze (SAE 660)PTFE compositesoil-impregnated sintered metalsengineered polymers (PEEKUHMW-PE).
Sealing
Double-lip contact seals or labyrinth seals
Clearance
C3 standard clearance (0.008-0.020 mm)
Lubrication
Grease-packed or oil-bath systems
Speed Rating
Up to 3000 rpm
Load Capacity
Dynamic: 5-50 kN, Static: 8-80 kN
Temperature Range
-40°C to +150°C
标准
ISO 15ISO 104DIN 625DIN 5412

常见问题

What is the difference between support bearings and bushings in agitator applications?

Bearings use rolling elements (balls/rollers) for lower friction at higher speeds, while bushings provide larger contact areas for better shock absorption and are often self-lubricating. Bearings offer higher precision, bushings handle more contamination.

How often should agitator support bearings be replaced?

Typical service life is 10,000-20,000 operating hours depending on load, speed, and environment. Regular vibration analysis and temperature monitoring can predict failure before catastrophic breakdown occurs.

Can support bearings handle both radial and axial loads in agitators?

Standard support bearings primarily handle radial loads. For combined loads, angular contact bearings or tapered roller bearings are recommended. Most agitator designs separate radial and axial load handling.
