The inner surface of the end housing 1 faces the slider 10.
As shown in fig. 3-4, preferably, the inner surface is provided with not only the oil passage 1-2 but also the oil storage chamber 1-1, the oil passage 1-2 passes through all the oil storage chambers 1-1, and the oil passage 1-2 and the oil storage chamber 1-1 are distributed over more than three parts of the inner surface of the end shell 1. The inner surface of the end shell 1 is attached to the end surface of the sliding block 10, so that the oil channel 1-2 and the oil storage cavity 1-1 can be sealed and leak-proof.
Preferably, the endless loop path comprises a sliding block 10 provided with a through rolling ball hole 3, the rolling ball groups connected end to end are arranged in the rolling ball hole 3, and the rolling balls can also pass through an oil duct 1-2 or an oil storage cavity 1-1 of the end shell 1 and are contaminated by lubricating oil/grease.
As shown in fig. 2, when viewed from the cross section of the slider 10, the rolling ball components are the upper rolling ball 4 and the lower rolling ball 9, the machine part is connected above the slider 10, the upper rolling ball 4 is in pressure contact with the guide rail 5, the upper rolling ball 4 is the most stressed rolling ball, so that the amount of lubricating oil/grease is large, and the lower rolling ball 9 is in contact with the side edge of the guide rail 5 and only has a collision effect, so that the oil consumption is small, and only the oil consumption of the oil ducts 1-2 of the conventional end housing 1 is needed.

This is to maintain a minute amount of oil supply for a long period of time. The through hole 15-1 with small diameter makes the lubricating oil not flow out under the action of surface tension, and the rolling ball is blocked on most of the through hole 15-1 to prevent the lubricating oil from falling. Of course, vibration occurs when the rolling ball rolls, so that the surface tension of the lubricating oil is broken and the lubricating oil is oozed out from the through hole 15-1.
Preferably, the through-opening 15-1 abuts against the bottom of the oil reservoir 6, so that the lubricant/grease can flow through as far as possible. The middle of the bottom of the oil storage tank 6 is convex and inclined to two sides, and the lubricating oil/grease flows to two sides.

The length L of the sliding pair main body 8 is more than L (the length of the sliding block 10) -D (the diameter of a rolling ball)/2, or L is more than L (the length of the sliding block 10) -0.2 mm.
The end shell 1 enters the oil ducts 1-2 through the oil inlet of the oil injection nozzle, and the lubricating oil/grease in the oil ducts 1-2 flows into the oil storage tank 6 again. Preferably, one or more oil storage chambers 1-1 are provided therein at a position higher than the level of the nozzle position of the end housing 1 and also higher than the level of the receiving groove 7, and lubricating oil/grease can be stored in the upper oil storage chamber 1-1, and the nozzle has an oil passage 1-2 directly connected to the receiving groove 7 of the sliding sub-body 8.
When in normal use, the slide block 10 is horizontally placed, the height of the bearing groove 7 of the sliding pair main body 8 is lower than that of the oil nozzle, one or more oil storage cavities 1-1 which are higher than the oil nozzle of the end shell 1 can be connected with the bearing groove 7 of the sliding pair main body 8 through oil passages 1-2, and when lubricating oil/grease in the sliding pair main body 8 is insufficient, the lubricating oil/grease can flow into the bearing groove 7 of the sliding pair main body 8.

The upper rolling ball 4 is contacted with the arc-shaped edge 15 of the sliding pair main body 8 and can also block the through hole 15-1.
The two ends of the sliding pair main body 8 are provided with the bearing grooves 7 which protrude out of the two ends of the sliding block 10 main body, the bearing grooves 7 are inserted into the oil duct 1-2 in the end shell 1, so that oil can be conveniently filled, and the oil filling structure of the sliding pair main body 8 can be simple.
