Stainless Bearings Common Problem Handling
Aug 07, 2017

In the process of CNC machining which will often encounter some common problems of Stainless Bearings bearing heat, shaft heat, and so on, when we encounter these problems how to solve it, is to provide some common problems, we hope that we have help.

(1) bearing heat. If the bearing oil is insufficient, should be refueling, and check the oil circuit is smooth; if the oil has impurities, should clean the bearings, replace the new oil, cleaning the filter; if the assembly is not good, journal and Stainless Bearings skew, In the bottom of the bearing seat gasket; if the bearing clearance is too small, should re-adjust the gap.

    (2) shaft heat. If the shaft of the oil or rubber seal is too tight, should adjust the filler back cover position; if the shaft and stainless steel bearing cover radial friction, should check and adjust the shaft and bearing cover radial clearance, usually 0.25 ~ 0.3mm.

    (3) less friction on the main friction surface. If the oil is low, the fluidity is poor, should be replaced by the ambient temperature of the oil; if the oil ring rotation slow, splashing bad, should check the oil ring is off, if the oil is dry, Rub the edge, the oil is too high to the oil to the standard height; if the adjustment gasket to block the oil, should check the adjustment of the gasket position.

    (4) oil spill. If the amount of oil should be adjusted, the oil supply should be adjusted to maintain the standard height of the oil level. If the sealing device fails, the gland or thicker sealing material should be pressed and replaced. If the bearing seat has holes and oil leakage, Or use the lead method to block the pores.

    (5) axial runout. If the bearing clearance is too large, should be removed gasket, adjust; if the rotating body (gear, tape wheel, etc.) dynamic balance is not good, should check and adjust the dynamic balance; if the bearing is not stable, should be tightened bearing bolts;Stainless Bearings Shaft installation offset, should be in the bearing seat ground gasket, adjust the coupling installation accuracy.

    Stainless steel bearing fracture failure is mainly due to defects and overload two factors. When the external load exceeds the material strength limit caused by part fracture known as overload fracture. The cause of the overload is that the host is faulty or improperly installed. Bearing parts of the micro-cracks, shrinkage, bubbles, large foreign debris, overheating tissue and local burns and other defects in the impact of overload or severe vibration will also cause damage in the defect, known as defective fracture. It should be noted that the bearing in the manufacturing process, the raw materials into the factory re-inspection, forging and heat treatment quality control, processing process control can be correctly analyzed by the instrument whether the existence of defects in the future must still strengthen control. But in general, the failure of the Stainless Bearings usually occurs mostly for overload failure.
