H-L68149/H-L68111 Taper Roller Bearing H-L68149/11 KOYO Roller Bearing 68149/10

Tapered roller bearing L68149/L68111 rodamientos included cup and cone there two parts.Cup is outer ring,

Cone comprise rollers, cage,inner ring.And the inner ring with the rollers and cage can be fitted separately from the outer ring.

The tapered roller bearings are generally used to support comnined load mainly consisting of radial load. The carrying capacity of axial load depends on the contact angle of raceway of outer rings. The bigger the contact angle is, the strongerr the capacity will be .

Outstanding features of SET 17 Tapered roller bearing L68149/11 rodamientos automotrices y agricolas KOYO bearing :

1)Higher load ratings :Tapered roller bearing with higher load ratings can accept radials loads or axials loads in one direction and combined radial and radial loads .This type of bearing is suitable for use under heavy load or impact load.

2)The outer ring can be mounted seperately from the inner ring assembly.

3) Mounted clearance is adjustable.

 bearings at high temperature :  

When temperatures rise when  bearings, first of all to determine whether there is an error, if the temperature is rising, you should immediately do the following:

(1). check cooling water pressure, flow and pipe systems are functioning correctly. If the water pressure may be filter clogged, cannot be processed in a timely manner, can shut down, when the confirmation work, put into use again.

(2.) should check the speed Governor oil pressure, if oil pressure may cause the cooling water of hydraulic valve to close.

(3.) check for abnormal noise bearing, and inspecting the KOYO bearings swing for exceptions.

(4). observation of taking oil sample oil color is changing, and for tests to see if bad. If confirmed when the deterioration, should be shut down replace new oil.

(5). check oil oil level is normal, if irregular, check that the tank Vent valve is closed. If it is closed, oil supplement, if sealant gasket oil leakage should stop processing.
