密封轴承比特和非密封轴承比特之间的差异


1.标准的开放式滚子轴承

标准开放的滚子轴承是轴承没有密封。 这意味着该

熊英格斯是开放给外面的碎片，这可以通过锥进入。

一个开放的轴承位的优点是，它们通常是便宜。 他们是

理想的钻浅孔，在数百英尺。 如果钻深孔

以开放的轴承位，你可能要拉出来的每个几百

脚清理在锥碎片释放他们。

2.空气制冷/制空爆轴承

空爆轴承配备的空气循环位。 这些位在空气

通道，供应到空气轴承，用于冷却和润滑轴承。

和清洗轴承从钻井碎屑。

3.密封轴颈轴承

密封轴颈轴承具有很好的耐久性和耐磨性。 代替

的锥形内的滚筒有一个浮动衬套。

套管通常是做出来的特殊材料是具有很高的耐

热和磨损（表面损伤）。

The differences between sealed bearing bits and non-sealed bearing bits


1. Standard Open Roller Bearing

Standard open roller bearings are bearings without a seal. This means that the

bear-ings are open to outside debris, which can enter through the cone.

The advantage of an open bearing bit is that they are usually cheaper. They are

ideal for drilling shallow holes, in the hundreds of feet. If drilling deeper holes

with an open bearing bit you will probably have to pull it out every couple hundred

feet to clean out the debris in the cones to free them up.

2. Air Cool / Air Blast Bearing

Air Blast Bearings are equipped on Air Circulation Bits. These bits have air

passage that supply air to the bearings for cooling and lubricating of the bearing.

and for cleaning of the bearing from the drilling debris.

3. Sealed Journal Bearings

Sealed Journal Bearings have very good durability and wear resistance. Instead

of rollers inside the cone there is a floating bushing.

The bushing is usually made out of special material that is highly resistant to

heat and galling (surface damage) .
