帶座軸承的維護(hù)方法
FSB帶座軸承由于填充優(yōu)質(zhì)潤(rùn)滑脂和用高性能的密封圈密封，因此在一 般的運(yùn)轉(zhuǎn)條件下可以無(wú)給油使用。
但是，在運(yùn)轉(zhuǎn)溫度高和塵埃、水較多等相對(duì)惡劣的環(huán)境中使用時(shí)，會(huì)使?jié)櫥踊瑢?dǎo)致潤(rùn)滑不良。需在適當(dāng)?shù)拈g隔時(shí)間進(jìn)行定期檢查來(lái)延長(zhǎng)軸承的使用壽命。
軸承的定期檢查是通過(guò)檢查外觀和運(yùn)轉(zhuǎn)狀態(tài)來(lái)判斷帶座軸承有無(wú)異常。
軸承定期檢查發(fā)現(xiàn)的主要異常內(nèi)容及其原因如下表:

注1)軸承的基本型號(hào)是，由直徑系列后續(xù)內(nèi)徑型號(hào)構(gòu)成。
潤(rùn)滑脂的補(bǔ)充是通過(guò)安裝在軸承座上的注油嘴和注脂槍來(lái)進(jìn)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(rùn)滑脂。
[注]：向帶座軸承補(bǔ)充潤(rùn)滑脂時(shí)，推薦一邊用手轉(zhuǎn)動(dòng)軸（或?qū)ёS承低速運(yùn)轉(zhuǎn)）一邊進(jìn)行。這樣可以將新的潤(rùn)滑脂均勻地補(bǔ)充到軸承內(nèi)部。
3、清掃殘留在注油嘴及周邊的潤(rùn)滑脂，并把油帽重新安裝到注油嘴上。
軸承的更換
FSB帶座軸承的軸承和軸承座具有互換性；如果軸承出現(xiàn)異常時(shí)，可以更換軸承繼續(xù)使用。
帶座軸承的更換過(guò)程如下所示：
1、將帶座軸承從軸、底座上卸下。
2、擰入止動(dòng)頂絲使頭部低于軸承內(nèi)圈的外徑面。防止軸承拆卸時(shí)，止動(dòng)頂絲的頭部與軸承座干涉。
3、用錘子的柄等，將軸承旋轉(zhuǎn)90°置于水平。
4、從軸承座安裝槽中取出軸承，將新的軸承按拆卸相反的過(guò)程進(jìn)行安裝。

Maintenance method of seated bearing
The FSB seated bearings are filled with high-quality grease and sealed with high-performance seals, so they can be used without oil under normal operating conditions.
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
| Abnormal content |
the reason |
| Excessive torque (heavy) |
1 Deterioration of grease |
| 2 Too much grease is added, and the sealing ring and the retaining ring contact |
|
| 3 The retaining ring is deformed and contacts the sealing ring |
|
| 4 Abnormal load caused by extension of shaft |
|
| There are abnormal sounds and vibrations |
1 Looseness of the retaining screw of the inner ring of the bearing or the mounting bolt of the bearing seat |
| 2 The mating surfaces of the shaft and the inner ring of the bearing wear due to creep or abrasion |
|
| 3 Foreign matter has penetrated into the bearing |
|
| 4 The raceway surface of the bearing is damaged due to rolling fatigue |
|
| 5 If the load is too large, the raceway surface of the bearing produces indentation |
|
| 6 Deflection or bending of the shaft is too large |
|
| Have abnormal temperature rise |
1 Deterioration of grease |
| 2 Too much grease is added, and the sealing ring and the retaining ring contact |
|
| 3 The retaining ring is deformed and contacts the sealing ring |
|
| 4 The retaining screw or lock nut (fastener) of the bearing inner ring is loose |
|
| 5 Abnormal load caused by elongation of axis |
|
| 6 The raceway surface of the bearing is damaged due to rolling fatigue |
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
FSB seated bearings are oil-supplied, and the same type of grease can be regularly replenished according to their use environment
to maintain the normal lubrication state of the bearing, thereby extending the service life of the bearing.

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 bearing and the bearing seat of FSB seated bearings are interchangeable; if the bearing is abnormal, the bearing can be replaced and used.
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.
4. Take out the bearing from the bearing seat installation groove, and install the new bearing according to the reverse process of disassembly.
