但是，在運轉溫度高和塵埃、水較多等相對惡劣的環境中使用時，會使潤滑脂劣化，導致潤滑不良。需在適當的間隔時間進行定期檢查來延長軸承的使用壽命。 

軸承的定期檢查是通過檢查外觀和運轉狀態來判斷帶座軸承有無異常。

軸承定期檢查發現的主要異常內容及其原因如下表:

定期檢查發現的主要異常內容及其原因

通過定期檢查發現軸承出現異常時，要迅速采取對策并加以實施。及時更換軸承，以免損壞其它零部件及發生重大事故。

潤滑脂的補充

注1)軸承的基本型號是，由直徑系列后續內徑型號構成。

潤滑脂的補充是通過安裝在軸承座上的注油嘴和注脂槍來進行：  

1、清掃注油嘴及油帽周邊，打開油帽后并清掃注油嘴。
2、清掃注脂槍，填充潔凈的潤滑脂。
[注]：向帶座軸承補充潤滑脂時，推薦一邊用手轉動軸（或將帶座軸承低速運轉）一邊進行。這樣可以將新的潤滑脂均勻地補充到軸承內部。
3、清掃殘留在注油嘴及周邊的潤滑脂，并把油帽重新安裝到注油嘴上。

軸承的更換

帶座軸承的更換過程如下所示：

1、將帶座軸承從軸、底座上卸下。

2、擰入止動頂絲使頭部低于軸承內圈的外徑面。防止軸承拆卸時，止動頂絲的頭部與軸承座干涉。

3、用錘子的柄等，將軸承旋轉90°置于水平。

However, when used in a relatively harsh environment such as high operating temperature and a lot of dust and water, the grease will deteriorate and cause poor lubrication. Regular inspections are required at appropriate intervals to extend the life of the bearing. 

The periodic inspection of the bearing is to judge whether the bearing with a seat is abnormal by checking the appearance and running state.

The main abnormal contents found in the periodic inspection of bearings and their causes are as follows:

The main abnormal contents found in regular inspections and their causes

When an abnormality in the bearing is found through regular inspections, countermeasures must be taken quickly and implemented. Replace the bearings in time to avoid damage to other parts and major accidents.

Replenishment of grease

Recommended grease replenishment interval for bearing components

Recommended table of grease replenishment for seated bearings

Note 1) The basic model number of the bearing is composed of the inner diameter model following the diameter series.

The replenishment of grease is carried out through the grease nozzle and grease gun installed on the bearing seat:  

1. Clean the oil injection nozzle and the periphery of the oil cap, open the oil cap and clean the oil injection nozzle.
2. Clean the grease gun and fill it with clean grease.
[Note ] : When replenishing grease to the bearing with a block, it is recommended to rotate the shaft by hand (or run the bearing with a block at a low speed). In this way, new grease can be evenly added to the inside of the bearing.
3. Clean the grease remaining in the grease nozzle and surrounding area, and reinstall the grease cap on the grease nozzle.

Bearing replacement

The replacement process of the seated bearing is as follows:

1. Remove the bearing with seat from the shaft and base.

2. Screw in the stopper wire so that the head is lower than the outer diameter of the inner ring of the bearing. Prevent the head of the stop screw from interfering with the bearing seat when the bearing is disassembled.

3. Using the handle of a hammer, etc., rotate the bearing 90° to level it.
